What are WebM and GIF files?
WebM (.webm)
WebM is an open, royalty-free video format designed for the web. Browser screen recorders often save WebM, but iPhones and many editors handle MP4 better.
GIF (.gif)
GIF is a classic image format limited to 256 colours, best known for short looping animations, memes and reactions. Its colour limit makes it a poor choice for photos.
Tips for the best GIF results
- Keep GIFs short (under 10 seconds) and around 480 px wide; higher frame rates and widths increase size quickly.
- For phones and social media, MP4 (H.264 + AAC) is the safest choice for video and MP3 for audio.
- Very large files (over 1 GB) may exceed browser memory on phones; trim them or use a computer.
- Bookmark this page or install the app to convert WebM files offline next time.
Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this WebM to GIF converter processes everything on your own device using FFmpeg compiled to WebAssembly — the same engine used by professional video tools. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.

GIF preserves the quality of your source file exactly — though it cannot restore detail already lost in the original WebM.

Yes. Drop multiple files and download them individually or together as a ZIP.

What is the difference between WebM and GIF?
WebM (WebM Video) is lossy (vp8/vp9/av1) and best for web embedding and screen recordings, while GIF (Graphics Interchange Format) is lossless (256 colours) and best for memes, short animations and simple graphics.
Why does the first conversion take longer?
The FFmpeg WebAssembly engine (about 30 MB) is downloaded once and cached. Later conversions start immediately.
