A way to compress PDF files on Mac OS X

PDF documents generated by the operating room Mac system OS X is noticeably larger in size than files with the same content created by Adobe Help Acrobat. If you are a Mac OS X user and want to reduce the size of the PDF file you create, do the following:

  1. Open the TextEdit application, then click on “File” in the program menu, and then select “Print”.
  2. In the lower left corner of the window that opens, you will see a button called PDF. Click on it, and then on the line “Compress PDF” in the drop-down list. The result is a more compact PDF file.

Archiving a file

To ensure that the document takes up less space on your computer, you can archive it using one of the archivers, for example, 7Zip or WinRAR. Both programs are quite popular, but the first is distributed free of charge, and you will have to pay to use the second beyond the limited trial period.

To compress a document using 7Zip, click on the file right click mouse, then with the left button of the manipulator, first click on the line 7Zip, and then on the inscription “Add to “file_name”. Then the archive will be created automatically.

If you want to set certain parameters before archiving, select the “Add to archive” line. Then a window like the one in the screenshot below will open.

By using an archiver, you can significantly reduce the size of a document, as well as create an archive consisting of several files, compressed and combined with each other. This will make it much easier to store and transmit them via email. Just before sending an archived PDF file, make sure that the recipient also has an archiver installed, otherwise he will not be able to open the archive.

Note: Adobe Acrobat and Adobe Reader are not the same thing. Reader is free, but its feature set for editing PDF files is extremely limited, so you can only reduce the size of documents in Acrobat. However, Adobe Acrobat is a paid program. And if you don’t have it and don’t want to buy it, use other options for compressing PDF documents that are not associated with it.

If you work with PDF files, you probably know that they can be large due to the images and graphics they contain. Fortunately, you can compress PDF files without even losing quality, thereby reducing its size. In this article, I will try to show you several ways in which you can reduce the size of your PDF file.

Method one - online converters

The easiest way to make your PDF file smaller is to use a free online tool called SmallPDF.com. The site is great (not filled with spam ads, etc.) and it does a good job of keeping the size down large files PDF. It is very convenient that you can use it anywhere and anytime operating system, and even supports new feature HTML 5 drag and drop.

Go to the website and click on Compress PDF. Then click on Drop PDF here Choose file and find the desired PDF file on your computer to compress. Afterwards, the service automatically begins its procedure.

He was able to take a 95.7 MB file from me and cut it down to 45.7 MB. This is a fantastic result, isn't it? Then click download compressed file.

Another online tool I use to compress PDFs is Neevia Compress PDF. It has many functions: high compression/low image quality or low compression/high image quality, etc.

The second way is using a free program

PDF Compressor - free program, which you can download for Windows XP/Vista/7/8, which allows you to quickly and efficiently reduce the size of one or more PDF files. You can download it from the link http://www.pdfcompressor.org

It supports lossless compression, so you won't see any reduction in quality in your PDF. It also supports encrypted PDF documents and can handle multiple or even thousands of PDF files simultaneously.

The third method is Adobe Acrobat PDF Optimizer

Starting with version 7 of Adobe Acrobat, there is a new feature in the Advanced menu called PDF Optimizer.

Now you are taken to a screen that has a whole bunch settings!

Click the Audit space usage button on the right top corner to get a detailed list of each component of a PDF file and how much space it uses.

As you can see, you can do different actions to reduce the size of a PDF file, including optimizing or scaling images, adjusting fonts, adjusting transparency, removing objects, and cleaning up the PDF file.

In the Images section, for example, you can resize and compress images to save space. This is really useful, especially if your images have really a high resolution. If you don't need to print the PDF, you can reduce the quality and pixels per inch. You only need 72 pixels to view on screen.

Look at all the settings and change them to suit your specific PDF file.

Hopefully one of the above methods will give your PDF file a reduced size that you can attach to an email or website post. If you use another method not mentioned above to shorten PDF files, please let us know in the comments. Thank you.

Video materials:

In this lesson 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).

Of 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 is intuitive clear interface In my opinion, it won’t be too difficult to figure it out, and you won’t be able to get lost in the functions either. 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):

In order to compress the required PDF file, 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 compression ratio of PDF 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 indicate 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 see original file weighs only 1.7 MB, which is very convenient for sending by email or uploading to a server.
