If you've been around PDF files often, you know that sometimes they can be quite heavy with images or other graphics. Fortunately, there are now many ways to compress any type of file, including PDF documents.
In this article I will tell you a couple of ways to reduce PDF size files. if you have Adobe Acrobat(not free), then it is much easier to do this, but we will only use free ways.
Method 1 - SmallPDF.com
This is the easiest way to make your PDF file smaller. Using this free service You can also convert PDF to: Word, PTT, JPG. In general, the functionality is very extensive, but we will return to our goal.
So, go to the website smallpdf.com. Next, select the language at the bottom of the screen.
Next, click on “ PDF Compression».
Now you need to either drag your document to the appropriate area, or select it in the standard way.
Then we wait a few seconds until the file is uploaded to the server and compression takes place. Upon completion, you will receive the following message (see screenshot below).
To download an already reduced PDF file, click the " You can save the file" By the way, the service works with cloud storage Google and DropBox, which is very convenient. You can upload files from the clouds, as well as move already compressed documents to them.
As you can see in the screenshot below, using this online service we were able to reduce the file size from 5.46 MB to 3.1 MB. Pretty good compression, and it's free
Among other online services, I would also recommend using pdfcompressor.com/ru/ or convertio.co/ru/compress-pdf/. I especially liked the last service, if you select it high degree compression, the document size will decrease by 15-20%, although there is no significant loss in quality.
Method 2 – PDF Compressor Program
Wonderful free program for compressing documents in PDF format. You can download it on the official website pdfcompressor.org. We install and start working with the program. First you need to upload the file, to do this, click on the “ Add file"or simply drag the PDF into the central area of the window.
Then click on the button “ Start Compression" After 10-15 seconds we will get the result.
The result did not console me, since my document was compressed by only 1 KB. But if you work with files larger than 20 MB, then PDF reduction occurs by 30-40%.
Compression using PDF Compressor is good because the document does not lose quality. It is also useful that in this program you can work with PDF documents in batch mode, compressing 100 or more files at a time.
Method 3 – Free PDF Compressor
Free and easy to use program. You can download it at freepdfcompressor.com. After installation, go directly to compression.
Upload the document by clicking on the " Browse" in the first line. In the second line we indicate the path where the compressed PDF file will be saved.
Next, select the compression format. Of the five presented, I recommend installing “ Printer..." In this mode, compression occurs with minimal loss of quality (purely my observation).
Now all you have to do is click on the " Compress"and wait until the program finishes processing each page of your document.
Question about reducing file size in pdf format often set by an active computer user. This is due to the large weight of the scanned images. Because of this, the document takes up hundreds of megabytes on disk. Let's look at the problem in more detail.
Using Adobe Reader
You can reduce the document size using free version Adobe programs Acrobat Reader. The compression function is only available at checkout paid subscription. The utility is installed without any problems, so let’s get straight to work.From home menu go to the “File” tab. Click on “Open” and select the document. IN in this example We will use a textbook weighing 69.9 MB. It consists entirely of scanned pages printed edition. You can also open a document by clicking on it in file manager. Go to the menu shown in the screenshot.
Leave the default values in the called window. Select a location to save the compressed pdf. The example file now weighs 33.3 MB. The compression took about two minutes. The quality of the images has deteriorated. This may not be noticeable on a website or computer. However, after printing, the illustrations will be fuzzy or completely blurry. The disadvantage of this method is that there is no flexible setting for an advanced user.
If installation is required additional parameters, then the optimizer will help. Open the document we need. Click on the button shown in the illustration below.
There are few settings, but they look difficult to master. Let's define the main ones. They are located in the left menu “Images”. Downsampling determines the resolution of images. To the right of the parameter you can set ppi (pixels per inch). Highly not recommended for printing. It is recommended when placing illustrations on the site. Below you can set the compression type. ZIP is used for simple images with a predominance of one color. JPEG - for any images. Its improved version is JPEG2000.
After setting, select a location to save the file. Let's compare the quality of the optimized document and the original. Left - original file, on the right - compressed.
Changes in quality are invisible even when the image is enlarged three times.
Using third party software
For the role free analogue PDF Compressor will do.
Intuitively clear interface and the light weight of the program will appeal to any user. In the upper left part of the window, you must click the “Add Files” button to open the document. You can also drag the file directly into the program's work area.
To optimize, click “Start Compression”. The button is located at the top center. First you need to set the compression parameters by clicking the “Compression Settings” button.
After opening the settings menu, you will be notified about purchasing a license. She is needed for fine tuning compression. Click “Continue” and check the boxes in the “Compression” and “Optimization” tabs. Close the window and click “Start Compression”.
During the compression process, the weight of the example textbook decreased from 69.9 MB to 56.9 MB. Let's compare the quality. On the left is the document before optimization, on the right is after.
The result is worse than Adobe Acrobat Reader. There is now noticeable distortion in the compressed file. The advantage of the program is that you can compress the file absolutely free. Consequently - worst quality and larger size. The utility logo is also added to the first page.
Using WinRAR
WinRAR is a free program with the option to purchase a license. Designed to place files in an archive and then compress them. The quality does not change. The original can be retrieved from the archive at any time.The utility work area shows file system your computer. Select the folder to create the archive. Click on “Add”. The button is on the left top corner. Here is the archive settings menu.
We are interested in the “Compression method” drop-down list in the “General” tab.
Their names speak for themselves. High-speed, less time-consuming, also has a low compression ratio. Maximum has the opposite characteristics.
Documents are added from the “Files” tab.
The file from the example was compressed in a few seconds. The file weight has changed from 69.9 MB to 68.3 MB. Conclusion: WinRAR does not work well with pdf files. The advantage of the program is that the original is preserved unchanged.
Using the online service ILovePdf
A convenient solution is web services for working with pdf files. ILovePdf can not only edit the contents of a file, but also reduce its size.
We start by clicking the big red “Select PDF files” button. An explorer will open where we specify the path to the pdf document.
After selecting it below, the compression settings will appear. They don't need any comments. Let's leave the recommended parameters. At the very bottom there is a “Compress PDF” button. Let's click on it.
After the compression process we get to new page and press the big red button again.
In the screenshot above we were also informed about changes in document weight. Instead of 69.9 MB, the textbook now weighs 55.9 MB. The result is similar to the result PDF applications Compressor. The difference is that you don’t need to download or install anything. Let's compare the quality. On the left is the optimized document, on the right is the original.
A slight loss of quality is noticeable; it does not affect the perception of information.
Using the SmallPdf online service
This service allows you to download files from Google Drive or DropBox. From a computer, documents are sent through Explorer or by dragging a file into a browser window.
Click on the big red button. To reduce the file size in pdf format, you don't need to click anything. It happens immediately after loading. Then download the document by clicking on the “Download file” button.
From the service, the document can be sent to Google Drive or DropBox (adjacent buttons). The illustration shows the volume of the compressed document. The file size has changed from 69.9 MB to 59.2 MB. Slightly more than the previous service. Let's check the quality. On the left is the compressed pdf, on the right is the original.
SmallPdf was able to compress the file with virtually no loss of quality. The downside of the service is the lack of compression settings.
To conclude, archivers do not work well with PDF documents, and best method compression is online services And standard tool Adobe.
In this tutorial we will learn how to compress a PDF file different ways and with different quality (respectively different sizes PDF file)
Our task: reduce the size of an existing PDF file in order to send it by mail or if we simply need a smaller document size.
What we have in stock: the actual PDF files themselves or the file that needs to be reduced in size.
What we get at the end:
In our case, I suggest using online services for working with PDF files (that is, all manipulations with PDF files will take place on the websites of the services we need).
From the large abundance of services and sites, I would recommend 2 of them, with the help of which we will reduce our PDF files to minimum size with maximum compression or up to “decent” compression but maintaining normal quality photos in a PDF document.
So, I present 2 services for working with PDF files: and . In principle, one service would be enough (SMALLPDF.COM), but the PDF-DOCS.RU service has something that I will talk about a little later in this lesson;)
SMALLPDF.COM
Let's start with the SMALLPDF.COM service. By clicking on the link above we will see something like this:
This service has an intuitive interface, in my opinion, it won’t be difficult to figure it out, and you won’t be able to get lost in the functions. Therefore, in our case, this is an excellent solution to our mini-problem.
Let’s say we have a “compress PDF” folder and it contains all the files or one PDF file that needs to be reduced in size (I have 1 PDF file in the folder):
To compress required file PDF, click the “Select file” button:
After selecting the PDF file we need, the file selection window will close and the service will begin manipulating the PDF file. The next thing we will see is the process of preparing and compressing the PDF file:
After passing the “100% Loading” stage, the page will refresh and we will see a block with the result of compressing our PDF file “big_file.pdf”:
From this data we learn that our original file “big_file.pdf” is compressed by 71% ( good result) and that now it “weighs” 2.84 MB, and was originally 10.14 MB. Below we are offered a link to download the already modified file:
Click “Download PDF” and the download of the compressed PDF file will begin:
Finally, in our “compress PDF” folder there are 2 files - an uncompressed file “big_file.pdf” and a compressed PDF file “small_file.pdf”:
With this service for compressing PDF files “SMALLPDF.COM” the lesson is completed, let’s move on to the next service with its distinctive capabilities “PDF-DOCS.RU”.
PDF-DOCS.RU
So it goes to . At the time of writing this lesson “Compressing PDF files” home page this service looked something like this:
Why did I choose this resource to solve our problem: in this service we can achieve higher coefficient PDF compression file compared to SMALLPDF.COM, but also the quality of photos and pictures in final file PDF (compressed) will be noticeably worse accordingly.
Let's start using the service. What we have at the initial stage: 1 PDF file in “raw”, uncompressed form:
First, we need to indicate to the service the PDF file that we want to compress. Click on the “Select file” button:
As a result of this, a new window will open in which we will specify the path to the PDF file. In our case, this is the “compress PDF” folder and the file located in it “big_file.pdf”. Next, we need to set the compression level of the PDF file; for this, there is a special field in the “PDF-DOCS.RU” service:
We click on this field (I highlighted it in the figure above), we are asked to choose from three options the degree of compression of the PDF file:
In our case (for maximum PDF compression) we use the item “ best compression" Now all parameters for compression are configured, click the “Forward!” button. and the service will begin downloading our source file and compressing it:
After clicking the button, the service will begin its work and a message will appear while the work is being completed:
After some time, after the “PDF-DOCS.RU” service has completed all necessary work above the compression of the PDF file, we are informed that the compression has been successfully completed:
Based on the data presented, we see that our compressed PDF file now weighs only 1.7 MB. This, in my opinion, is a very good result in terms of the quality of the drawings in the PDF file.
Now we need to download our compressed PDF file. To do this, click on the link below in the “Download file:” field. In our case, the link to the file will be called “new-314_big_file.pdf”, click on this link to download the file:
Clicking this link will begin the process of downloading the PDF file. In some cases, depending on the browser and settings you are using, clicking on the download link may cause it to open in the browser. If the file opens in a browser, simply save it to your computer.
As a result of our manipulations to compress the PDF file, we have 2 PDF files in the “compress PDF” folder:
As we can see, the source file weighs only 1.7 MB, which is very convenient for sending by email or uploading to a server.
Now many computers already have hard disks ranging in size from hundreds of gigabytes to several terabytes. But still, every megabyte remains valuable, especially when we're talking about O fast loading to other computers or the Internet. Therefore, it is often necessary to reduce the size of files to make them more compact.
There are many ways to compress a PDF file to the right size, so you can then use it for any purpose, such as sending it via email in a matter of moments. All methods have their pros and cons. Some weight loss options are free, while others cost a fee. We will look at the most popular of them.
Method 1: Cute PDF Converter
The Cute PDF program replaces a virtual printer and allows you to compress any PDF documents. To reduce weight, you just need to configure everything correctly.
It is worth remembering that a decrease in quality entails file compression, but if the document contained any images or diagrams, they may become unreadable under certain conditions.
Method 2: PDF Compressor
Until recently, the PDF Compressor program was just gaining momentum and was not so popular. But then, too quickly, it received a lot of negative reviews on the Internet, and many users did not download it precisely because of them. There is only one reason for this - the watermark in the free version, but if this is not critical, then you can download it.
File with initial size The program compressed just over 100 kilobytes to 75 kilobytes.
Method 3: Save PDF at a smaller size using Adobe Reader Pro DC
Program Adobe Reader Pro is not free, but it does a great job of reducing the size of any PDF document.
The method is very fast and quite often compresses the file by almost 30-40 percent.
Method 4: Optimized file in Adobe Reader
For this method, you will again need the program. Here you will have to tinker a little with the settings (if you want), or you can just leave everything as the program itself suggests.
Method 5: Microsoft Word
This method may seem clumsy and incomprehensible to some, but it is quite convenient and fast. So, first you need a program that can save PDF document V text format(you can search for it among the Adobe line, for example, Adobe Reader or find analogues) and Microsoft Word.
That's it in three simple steps you can reduce the size of a PDF file by one and a half to two times. This happens due to the fact that DOC document saved in PDF with the weakest settings, which is equivalent to compression through a converter.
Method 6: Archiver
Most the usual way compress any document, including a PDF file, using an archiver. For work it is better to use 7-Zip or WinRAR. The first option is distributed free of charge, but the second program expires trial period asks to renew the license (although you can work without it).
The PDF file is now compressed and can be used for its intended purpose. Sending it by mail will now be much faster, since you won’t have to wait long for the document to be attached to the letter, everything will happen instantly.
We have considered the most best programs and ways to compress a PDF file. Write in the comments which method was the easiest and fastest for you to compress the file, or suggest your own convenient options.
