⬇ Download GIFHow to make a GIF from images
- Pick the image frames in playback order. JPG, PNG and WebP all work.
- Set a frame delay — 100 ms ≈ 10 fps; 40 ms ≈ 25 fps (smoother but larger).
- Set the output width — keep it small (320–480 px) to keep file size sane.
- Press Build GIF, wait for ffmpeg.wasm to finish, then download.
Common use cases
- Product demos on a landing page or in a README.
- Tutorial screenshots stitched into a quick walkthrough.
- Reaction GIFs built from 4–8 hand-picked frames.

常见问题
- How many images can I combine?
- Most browsers handle 200+ frames comfortably. Very long sequences may run out of memory on mobile devices.
- Why is the first run slow?
- ffmpeg.wasm is about 25 MB and is downloaded once, then cached. Subsequent runs reuse the cache.
- Are my images uploaded?
- No. ffmpeg.wasm runs entirely inside your browser via WebAssembly.
