. PNG file extension.
The PNG extension is a file format used to store images without loss of quality. This is the most popular format photos on the Internet, specially designed for use on the Web.
What's in PNG files
A file with a PNG file extension is a file Portable Network Graphics. The format uses lossless compression and is generally considered an alternative to GIF. But unlike , PNG files do not support animation.
The PNG format has both grayscale and full-color photographs, and transparent layers are supported. PNG compression usually better than that, which is used in GIF. JPG is sometimes superior to PNG, but the compression can cause artifacts in images with text or around high-contrast areas.
How to open a PNG file
To open PNG files, you can use any Internet browser or graphics editor. Both Windows and Mac OS platforms have built-in mechanisms for viewing such images. Png program- View Windows photos the default is often used to open PNG files because it system program Windows. But there are many other ways to view them.
All browsers (eg Chrome, Firefox, Internet Explorer etc.) will automatically view PNG files you open on the Internet, meaning you don't have to download every PNG file you want to view onto your computer. You can also use your browser to open PNG files already on your computer using the combination Ctrl keys+ O. Most of these programs also support drag-and-drop, so you can simply drag the PNG file into the browser to open it.
PNG conversion
Image files can be converted different ways eg convert to and from png using various programs And online services. For example, this can be done by the Png editor - Photo Converter.
An image file that is stored in the Portable Network Graphic (PNG) format. Contains a bitmap of colors and uses lossless compression, similar to a file, but without restrictions on copying. Typically used to store web image graphics.
The PNG format (pronounced .png) was created in response to the format's limitations, primarily to increase color support and provide a patent-free image format. In addition to this, while the files
One of the main tasks facing designers of new sites is fast loading browser pages. And since not all users like minimalistic design, we have to look for a compromise between beautiful design with graceful graphic elements and the speed of the web resource. Previously, in order to reduce the weight of images, website developers used either GIF or JPG. Nowadays, layout designers are increasingly using images in PNG format. Let's try to figure out together why this happens.
Why was the PNG format invented?
The abbreviation that is the name of this type of graphics is formed from the first letters of the following English words: portable network graphics, which can be translated as “movable graphics for use on the network.” The PNG format was specifically invented to eliminate the disadvantages of compression using the simpler GIF algorithm, which was slowly beginning to become obsolete. In addition, it can to some extent be used to replace the much bulkier TIFF, which is used mainly for editing.
What is the PNG format?
Today, two versions of this algorithm are widely used. In the first case, 8-bit is used, and in the second, 24-bit. Photos in PNG-8 format, compared to the GIF version, are slightly better and lack the ability to create animation. Although it can contain a maximum of 256 colors, this algorithm Widely used to create graphic text, logos, illustrations with sharp edges and pictures with gradient transparency. In cases where this is clearly not enough, developers use the 24-bit PNG format, which has a lot of additional benefits, such as:
- Improved negating any loss of quality.
- The ability to use alpha transparency provides 256 different levels of transparency.
- The presence of gamma correction, which allows you to automatically adjust the brightness of the image when playing back in different programs.
- Possibility of using about 16.7 million color shades.
All this together contributes to the use of PNG24 for compressing any images containing transparent areas, drawings with a lot of colors and clear image boundaries.
Development trend
Despite the fact that the spread of the PNG format is still hampered by older browsers, as well as insufficient and incomplete support for the capabilities of this algorithm in new versions, PNG is very promising for web graphics. Compared to GIF, it has three main advantages: alpha channels, gamma correction, and 2D interlacing (a method of progressively displaying an image). And compared to JPEG, it has no quality loss. Note that the PNG format was invented on January 4, 1995. 18 years have passed since then, and it has become the leader in use on websites, pushing GIF into second place.
Most user applications (for example MS Paint) today have adopted it as the standard for saving files “by default”. Probably, if not for the animation and quirks of the old Internet versions Explorer, GIF would have given way to its competitor even earlier.

Raster graphic format PNG emerged as a kind of maidan of free developers against the technological oligarchy, acquisitiveness and thirst for profit that were stifling the development of the Internet.
In the mid-nineties of the last century, the First Internet Revolution was in full swing. Consortium worldwide network W3C, as a result of a bloodless coup, removed the legally elected (by bribing the electorate) Temporary Representation in the person of Microsoft and Netscape. The latter were unable to agree on standards and brought the young digital civilization to the brink of a browser war.
There is an urgent need to introduce universal unification of Internet technologies. However, the GIF graphics format that existed at that time had a small but significant drawback– he had a commercial license, including data compression technology.
As usual, no one wanted to pay, therefore, in order to avoid chaos on the World Wide Web, when the sites of one developer cannot be viewed on the browsers of another, a group of volunteer programmers created the PNG specification, which turned out to be no worse than GIF, and in some respects had significant advantages.
Technical features of the PNG format
In general, if you look closely, PNG differs from GIF about the same way MS Office differs from LibreOffice. At the core raster graphics compressed, indexed color palette. However, the PNG developers took into account the errors of GIF and managed to eliminate new technology from the oppressive problems of the past.
- PNG data compression scheme provided recovery original image completely lossless regardless of compression level.
- Higher level of data compression.
- It was allowed to use an unlimited number of colors in the image. This made it possible to ensure the quality and realism of the picture almost at the level of the JPEG photographic format.
- Support for multi-level transparency of layers.
- The PNG format allows you to save all intermediate stages of image editing and restore any step without loss of quality.
There were attempts to create versions of this format with the possibility of animation, but they were no longer in demand - at the beginning of the 21st century, the license expired and the GIF graphics format became free for use for any purpose.
Scope of application PNG
Portable Network Graphics roughly translates to "portable network graphics." Even in the name of the project, there is a noticeable imitation of GIF - “graphic format for exchange over networks.”
To disavow the dark past, the creators of PNG spread the recursive acronym “Ping is Not a GIF” on the Internet.
Ping is the British pronunciation of PNG, in American English it sounds more like P-n-ji, for a Russian-speaking observer - peenge.
In fact, the revolutionary graphics packaging format turned out to be very good and today is the most popular for preparing images for publication on websites, blogs and in social networks thanks to its outstanding qualities.
- Cross-platform – read equally well by all types modern browsers and graphic editors.
- Has low weight high quality Images.
- Easily compressed in a wide range without loss of quality.
However, when posting photos on sites for viewing on screens computer monitors, especially on small displays mobile devices, users will not notice any difference between a PNG and a JPEG photo. More precisely, to notice the difference you need to either look closely or be a professional photographer.
For websites, the light weight of images is more important so as not to slow down the loading of web pages.
If we take into account the statistics that, on average, visitors spend only a few seconds on websites, and the content is not studied in detail, but is superficially scanned with a quick glance, then the quality of the PNG image turns out to be optimal.
Advantages of PNG over JPEG
In the process of repeated compression and editing of the image in JPEG files become distorted, color halos appear, and pixel blocks may fall out.
If you need to publish a very clear diagram on a website page, with legible small details, infographics - here PNG shows significantly top scores than JPEG, which is optimal for packaging images in which the main requirement is realism - photographs of natural landscapes, animals, people.
Possibility of creating transparent layers makes the PNG format indispensable for developing logos, icons, symbols, and buttons.
PNG has a function for storing metadata - date, time, place where the image was created, information about the author, copyright holders, etc. This is useful to remember when you are going to publish a picture borrowed from the Internet. To prevent Google from identifying a duplicate, you need to remove metadata from the file (using a graphic editor).
Free online image converter to PNG
On this site you can easily convert almost any image into PNG format, and you can set the color depth from 1-bit to 64-bit, as well as set the compression level. 
Please note that in order to maintain transparency in the resulting image, you need to use depth with RGBA colors. In this case, the letter A means alpha channel, i.e. transparent.
PNG optimization
Not all programs do PNG with minimum size file. Therefore, before publishing a picture on the site, it is recommended to optimize it. For these purposes, you can use various utilities, or use our online optimization service. Just select an image and click "Optimize".
