The Graphics Interchange Format (better known by its acronym GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability. The Animated Portable Network Graphics (APNG) file format is an extension to the Portable Network Graphics (PNG) specification. It allows for animated PNG files that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files. GIF supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. The first frame of an APNG file is stored as a normal PNG stream, so most standard PNG decoders are able to display the first frame of an APNG file. The frame speed data and extra animation frames are stored in extra chunks (as provided for by the original PNG specification).Īpple Safari, Google Chrome, Mozilla Firefox, Internet Explorer, Adobe Photoshop, Paint Shop Pro, the GIMP, ImageMagick, IrfanView, Pixel image editor, with any compression algorithm, the compression inside PNG can be configured to trade speed for compression. fastest, normal, maximum, ultraĪlso, the PNG file format has several filters which can be used to increase compression, and these filters can be applied on regions on the image.Ī built in (inside a programming language) PNG compressor will never be configured for the highest compression settings, where it takes significantly more memory (ram) and cpu time to compress image. A built in PNG compressor will almost always be on the "fast" or "normal" compression, and doesn't waste time optimizing the compression - if you want that, you're always free to write your own code or use separate png compression libraries. You can find an up to date table for APNG support in different browsers at. Comparision of different animated image formats ».It can import APNG, WebP, GIF, FLIF, and MNG animations, as well as archives of images (ZIP, RAR, 7z).Īnimated PNG files work similarly to animated GIFs but can contain more colors, partial (alpha) transparency, and other features for much greater image quality. You can also use it to edit existing APNG (change frame order, animation speed, disposal method), merge multiple APNG files, add or remove frames from animation or convert other types of animated images to APNG. If you are making an animation with transparent areas, it's possible to use the first frame as a background image for the rest of the frames. It gives you options to change frame order using drag and drop, set frame disposal (whether or not to keep the previous frame in the background), set loop count, or skip the first frame. This tool will assemble individual image files into an animated PNG file. ![]()
