Convert video to GIF or animated WebP — in your browser

Drop a video, trim the part you want, and Tinier converts it to a GIF or an animated WebP locally on your device using ffmpeg. Nothing uploads. No signup. Pick the frame rate, size and colors, watch the real progress, and download. GIF for maximum compatibility, WebP for a file 3–10x smaller.

GIF or animated WebP — which should you pick?

GIF is the universal animated format. It plays in PowerPoint, email, old chat clients, everywhere — but it is capped at 256 colors and the files are heavy because GIF was never designed for video. Animated WebP keeps far more color, compresses 3–10x smaller at similar quality, and every modern browser opens it. The one catch is that some older software cannot read WebP yet. Tinier lets you export either, so you choose compatibility or size per clip.

How to make a smaller GIF

A GIF's size depends mostly on motion, frame rate, dimensions and color count. Trim to just the seconds you need — every extra second is more frames. Drop the frame rate to 10–15 fps; the eye rarely misses it in a short loop. Shrink the longest side to 320 or 480 px for chat and docs. Fewer colors (64 or 128) helps flat content like screen recordings. If it is still too big, switch the output to animated WebP for a step-change in file size.

Why convert video in the browser instead of on a server?

Most online converters upload your video to their server, convert it there, and send the result back — your clip sits on someone else's hardware until they decide to delete it, and the round-trip adds real time. Tinier does the conversion locally with ffmpeg-wasm and your video never leaves your device. Privacy here is structural, not a checkbox in a privacy policy. The trade-off is honest: the engine downloads once (about 31 MB) and heavy clips lean on your device's memory, so very large videos convert faster on a laptop than on an old phone.

Frequently asked questions about converting video

Does my video get uploaded to a server?

No. The conversion runs in your browser with ffmpeg compiled to WebAssembly. Your video never leaves your device. You can disconnect your internet after the page loads and it still works.

Should I export GIF or animated WebP?

GIF plays everywhere, including PowerPoint and old chat clients, but it is limited to 256 colors and the files are large. Animated WebP is 3–10x smaller at similar quality and every modern browser supports it, but some older software cannot open it. Pick GIF for maximum compatibility, WebP for a much smaller file.

What video formats can I convert?

MP4, MOV, WEBM, MKV, AVI and FLV. Formats the browser cannot preview directly (like MKV or FLV) still convert — Tinier reads them with ffmpeg and falls back to numeric trimming when a live preview is not possible.

Why is my GIF so large?

GIF compresses video content poorly — it stores indexed frames, so file size grows with motion, frame rate, size and color count. Lower the fps, shrink the size, or reduce colors to make it smaller. For a dramatically smaller file, export animated WebP instead.
