(The other 4 conversion tools -apng2webp, gif2webp, gif2apng and webp2apng - were available since summer.)
Check out these 3 animated pictures (actually 2, because I cannot upload a .webp as an image apparently - despite the png extension, it is a WebP).
I bet you can't. That's because the companies behind the 3 most widely used internet browsers are unable to reach a consensus about what file format should web designers use for simple animations. There is GIF, but that is limited to 256 colors, the compression is not stellar and it does not support full alpha. Then there is animated PNG introduced in Firefox years ago. Adopted by Opera, but who cares now, right? Chrome did not want to lag behind, but for reasons unknown to me and apparently many others, instead of adopting animated PNG, they created their own format WebP. Firefox (of course) refused to adopt WebP. Internet Explorer (as always) plays dead and does not care about innovation, so neither animated PNG nor WebP is supported.
Here, webp2gif and apng2gif come to help you. If you decide to use for example WebP as the primary format for your graphic assets, you can use webp2gif to quickly generate GIF alternatives for all WebPs.
The tool(s) can scan all files in a folder and convert them. There are ways to skip already converted files so you can re-run the same command after you have made changes to your animations and it will convert just the changed/added files. It can also skip all non-animated images.
Either command line switches or hacky renaming tricks can be used to adjust the behavior of the tool. More info on the home page (or just ask in this thread).
Converts animated images in PNG or WebP format to GIFs for those conservative Internet Explorer visitors to your website/blog.
Open to suggestions.
Command line tool, so nothing to see here.
Using the Application
You can either use it from a command line or you can drag and drop files or folders on it.
Rename it, put it on the desktop and drag and drop folders with animations on it.
All issues are still unknown.
