Note that the functionality of this page is deprecated. Adobe has announced that it will stop supporting Flash Player at the end of 2020, so SWF files will be unable to load for conversion. Browser vendors may move to phase it out quicker. This page may stop working earlier than that depending on what browser you are using. Animators and developers may want to consider other options for authoring animations. Check out OpenToonz or Synfig, both of which can export PNG sequences that can be built into Animated PNGs on the home page.
This SWF conversion page may be deleted by 2020 or earlier.
Flash developers/animators can now use APNGs to play their animations on iPhones and iPads natively in full true color with a high quality framerate. Just add your .SWF files as images in the WebApp and generate some APNGs with the SWF-to-APNG functionality! Being a multi-frame bitmap format, these animations will, of course, lose the ability to run any code and vector scalability. Some animations may experience some
warping since the animation is being rasterized to fixed frames.
Why convert from Flash to make APNGs? Flash has been an industry leading animation technology for decades with many years of existing content of amazing quality built. Leveraging the deep feature set will also allow developers to build new breathtaking animations. The APNG format allows animations to play on mobile devices such as iPhone, iPad and devices running other supported browsers such as Firefox.
Very old AS2-based files(Flash 8 and below) will need to be converted to a non-ancient version before they will work here. This is because the AS3 system needs to be able to manipulate their timelines. If this is the case, load your animations into Flash Professional and re-save them in the latest format.
If your animation is based on code rather than a pure timeline animation, it may produce unpredictable results.
