WebM to GIF converter

WebM clips — screen recordings, exported animations — into shareable GIFs, converted on your device.

One video — MP4, MOV, WebM, MKV… · converted on your device, nothing is uploaded

No size limit · files are processed on your device and never uploaded · how it works

On phones this converts instantly with nothing to download. On desktop it uses FFmpeg (31 MB, once — saved on this device) for the best palette and dithering.

Advanced settings (optional)
GIF options
Frame rate

12 fps reads smooth for screen recordings and clips; 8 halves the size; 20+ only for fast motion.

Width

GIF size grows fast with pixels — 480 px suits chat and docs; keep original only for small sources.

Trim: start at

Seconds into the video (e.g. 4.5). Empty = from the beginning.

Trim: length

Seconds to keep (e.g. 6). Empty = to the end. Short loops make the best GIFs.

Look

Smooth blends colours (photo-like video); Crisp dithers in a pattern — smaller files, sharper flat graphics.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

This page opens the Video to GIF converter with WebM input in mind — trim and size it, then download the previewed file.

This is a pre-set view of the Video to GIF. Every option in the toolbar can still be changed.

Frequently asked questions

Where do WebM files come from?

Browser screen recorders, OBS, Discord clips and web exports. Some apps and documents refuse WebM — GIF pastes anywhere, which is usually why you are converting.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
