Why animated WEBP files cause trouble
Many websites now serve animations as WEBP instead of GIF because the files are lighter. When you save one of those reactions, stickers or product animations, you get a .webp file, and that's where problems start. Some messaging apps, email clients, presentation programs, forums and older image viewers don't play animated WEBP, or show only a still picture.
GIF is the format practically everything understands. Converting the WEBP keeps the animation and makes it work in places like Outlook newsletters, PowerPoint or Keynote slides, help desk tickets, Discord or Slack messages and older phones.
Keeping the animation intact
The tool reads the WEBP frame by frame and rebuilds the same sequence of frames as a GIF. Up to 300 frames are handled. You can keep the original size or shrink the longest side to 320, 480 or 720 pixels, which is often a good idea: GIF files are usually heavier than WEBP, and a smaller size keeps the result easy to send and quick to load.
Turn on repeat for a loop that never stops, the usual choice for reactions and stickers, or leave it off so the animation plays once.
Things to know before converting
Reading an animation frame by frame needs Chrome, Edge or Firefox. Safari can't do it yet; if you open the page there, it tells you instead of producing a broken file. On an iPhone, a desktop browser is the easiest way around it.
GIF shows at most 256 colors per frame. Cartoons, stickers, text animations and UI recordings look clean. Animations with photographic gradients may show some banding or grain compared with the WEBP, because WEBP can show many more colors. If you only need a still picture, WEBP to JPG or WEBP to PNG is the better route.
Common situations
You saved a funny reaction from a website and your group chat shows it as a frozen picture. You want to add a short product animation from an online store to a slide, and the presentation program only animates GIF. A newsletter tool or an email client rejects the .webp extension. A forum, a wiki or a bug tracker asks for GIF attachments. In all of these, the content is fine; only the format is wrong.
Designers also convert WEBP exports back to GIF when a client's older system or ad platform needs GIF. If the result is too heavy for the place you're posting, convert again at 320 px, which usually brings the size down a lot.
Private and free
The conversion happens in your browser. The WEBP file is never uploaded or stored, there's no sign-up and no watermark on the GIF, and it's free with no daily limit.
