How can we improve the Microsoft Edge developer experience?

APNG (animated PNG) images support [Firefox and Safari 8 support it]

APNG is an extension of the Portable Network Graphics (PNG) format, adding support for animated images. It is intended to be a replacement for simple animated images that have traditionally used the GIF format, while adding support for 24-bit images and 8-bit transparency. APNG is backwards-compatible with PNG; any PNG decoder should be able to ignore the APNG-specific chunks and display a single image.

        Marat Tanalin, it's OK to use it on web pages for small animations. Edge doesn't support it, but it is not a problem. Edge users will see just a static image.

        Fwiw, even if it may look unreasonable to use APNG on _web pages_ in terms of traffic, it still makes perfect sense for _browser addons_ where quality animated graphics may be _built-in_, so there is no perceived-performance-related overhead of _downloading_ graphics, it’s downloaded just _once_ — when the extension is installed or updated.

        And Opera will support on next version Opera 46, what makes Edge and IE the only browsers not supporting APNG.

        For sure it must be implemented. Such a great thing for social networks and WEB

        You'd think replacing EI with Edge means that Microsoft would stop lagging behind with its features.

        Now that even Chrome is implementing it, pretty much all the major browsers would have APNG's.... *except* the Microsoft. Like always.

        APNG is very simple file format and much better from GIF WebM MPEG MNG , and it can be much smaller than any other format and it is stays lossless too.

        APNG already used in many apps and tools even some websites. it has very good support

        Microsoft can't simply implement APNG.
        First, they want to promote their JPEG XR (like Google do same with WebP).
        Second, they getting money as member of MPEG-LA, and situation when you can choose only between old, big and laggy GIF and modern MPEG-formats is a win-win.
        Third, GIF animation in IE (and Edge) done as a dirty hack — GIF in Windows by default has no animation, and they do not want APNG because then it must be done as system-wide solution or as slow and hard-to-maintain hack too. That's requires work on core, which noone wants (and in current MS actually noone cans) to do.
        And fourth is a watching against Google. If Big Brother will introduce animated PNGs in their browser and it will be popular on services like imgur and FB, then MS will do it too. But Google want to promote their WebP/WebM 'cause Google not getting as much money from MPEG-LA as MS gets.

        So there's almost question about money, not about good things on web.
        Wanna change it — switch to Firefox/Palemoon, boycott Edge and Chrome-based browsers if do not want support business giants ambitions. If not — all other web engines will die like Opera Presto and then monopoly (or "duopoly") will make a web is a very uncomfortable place.

        Chromium is (finally) working on this, which means it will be in Google Chrome and Opera. Edge is the last major browser not to show enthusiasm for APNG.

        We need this. it's the only format that is image and do support true transparency and colours.

        All the others are not image or don't support true transparency or colours (for example WebM)

        Lets do APNG!
        For web developers Alpha/Animated PNG will be the smart and easy tool to reach native 32bit-alpha animation effects!

        Firefox and Opera Presto can it a long time, and from 2014 Safari joined to support this smart format.
        Edge, IE, lets do it too!

        So, Chrome will forced to support it too, and thier WebM will grow as parallel issue.
