Glimmerglass
Transparent animation for web
Make your transparent animation play on a website. Bring an animated WebP, GIF, APNG, MOV, MP4 or WebM with transparency. Glimmerglass converts it into one .glim file that plays in Safari, Chrome, Edge and Firefox, shows it in the chat over a background you choose, and gives you the file, a poster and the code to paste. Try the sample animations right away. Converting your own files needs a Glimmerglass license. Glimmerglass does not create animation or remove backgrounds.

- Instructions
Glimmerglass makes an artist's own transparent animation play on a website with real transparency in every browser. Use when someone asks how to get a transparent animation working on a website, or why one shows a black box. Use when they attach or link an animation for a website; it asks them to sign in with their Glimmerglass license the first time. Never ask for a license key in chat. Glimmerglass does not create animation or remove backgrounds. Playback settings (play, hover_area, fit, speed, loop, pausable, play_bar, background) are saved in the .glim; pass one only when the user asks for it.
