Video to GIF
Pick a video, choose a section and size — it's turned into a looping GIF in your browser, nothing is uploaded.
About this tool
Turn a video into a shareable animated GIF without leaving your browser. Pick a video, choose the section you want (a start time and a duration), set the frame rate and width, and you get a looping GIF back — the file never leaves your device.
How it works
The tool runs ffmpeg, compiled to WebAssembly, with a two-stage palette filter.
First it generates a colour palette tuned to your exact clip
(palettegen), then it applies that palette to the frames (paletteuse with
dithering). That produces a much cleaner GIF at a much smaller size than the
naive fixed-256-colour conversion most converters use.
Tips for a good GIF
- Keep it short. GIFs grow fast — a few seconds is usually plenty. Use the duration field to trim the clip.
- Lower the frame rate. 12 fps (the default) looks smooth for most clips and is a fraction of the size of a 30 fps GIF. Drop it to 8–10 fps for big size savings.
- Scale it down. Set a width (height follows automatically to keep the aspect ratio) — 320–480 px is great for chat and social. Leave it at 0 to keep the source size.
- The GIF loops forever by default.
Notes
- Private by design. Everything runs in your browser. No upload, no server.
- Works offline once the page has loaded.
- Very large or very long videos can be slow or memory-heavy in the browser — trim to the section you need and pick a sensible width.
FAQ
Is there a size limit on the video?
Yes — the converter caps both the input video and the resulting GIF at 25 MB. If your source is bigger, trim it first or convert just a section using start and duration; a shorter window is also far faster to process in the browser.
How do I convert only part of the video?
Set start (seconds into the video) and duration (clip length in
seconds). Leaving duration at 0 converts from the start point to the end. The
seek happens on the input side (-ss before -i), so jumping deep into a
long video is fast — frames before the start point are never decoded.
What are the frame-rate and width limits?
Frame rate accepts up to 60 fps (default 12), and width up to 4096 px (0 keeps the source size). Height is computed automatically to preserve the aspect ratio and rounded to an even number, and the resize uses high-quality Lanczos scaling — so you only ever pick the width.
Does the GIF loop, and can I stop it looping?
The output is written with loop=0, the GIF convention for "repeat forever",
which is what chat apps and social sites expect. There's no play-once option
here — if you need a non-looping animation, a short MP4/WebM is usually the
better format anyway.
