GIF Maker

Turn a sequence of images into an animated GIF — perfect for reactions, demos, and product showcases. Configure frame delay and output width. All processing happens in your browser via ffmpeg.wasm.

How to make a GIF from images

  1. Pick the image frames in playback order. JPG, PNG and WebP all work.
  2. Set a frame delay — 100 ms ≈ 10 fps; 40 ms ≈ 25 fps (smoother but larger).
  3. Set the output width — keep it small (320–480 px) to keep file size sane.
  4. Press Build GIF, wait for ffmpeg.wasm to finish, then download.

Common use cases

Frequently asked questions

My GIF is huge. How do I shrink it?

Lower the width, raise the frame delay (lower fps), or use fewer frames. For motion-heavy content, an MP4 is often 10× smaller — see GIF to MP4.

Why does my GIF look posterised?

GIF is limited to 256 colours per frame. A palette pass keeps colour balance close to the source; large colour gradients still get banding.

Are HEIC photos supported?

Not directly here. Convert iPhone photos first with the HEIC to JPG tool, then feed the JPGs into the GIF Maker.
