How does a video become a GIF?
A GIF is a series of still frames shown one after another and looped. Unlike a video, it carries no sound and uses a limited palette of colors per frame. That makes it simple and supported nearly everywhere, but also means GIFs get large quickly as they get longer or wider.
To make one from a video, a tool samples frames from the clip at a fixed rate, shrinks them, and packs them into a looping image. Fewer frames and smaller dimensions keep the file manageable, which is why GIFs usually work best for short moments.
When a GIF is the right choice
GIFs are handy for short, silent illustrations: a quick demonstration of a button click, a reaction clip, a bug that happens in a few seconds, or a small animation for a chat message or document. They autoplay and loop without any player controls, which is exactly why people choose them over a video link.
If you need sound, a longer clip or the best possible quality, a normal video is a better format. For long sources, cut the section you want first with Trim Video so the GIF only covers the moment that matters.
How to make a GIF with this tool
- Drag a video onto the upload area, or click to select one.
- There are no sliders or time fields on this page. The tool uses fixed settings: 10 frames per second and a width of 480 pixels, with the height scaled to match.
- Click Run. The first time, the ffmpeg engine (roughly 30MB) downloads, then the conversion runs.
- Check the preview, then click Download. The file is named after your video with "-gif" added.
The conversion runs in your browser with ffmpeg.wasm, so your video is not uploaded anywhere.
Keeping the result a sensible size
This tool converts the whole video, not a selected section, and there is no setting for length. A long source will produce a very large GIF and take a long time to process, and a browser may run out of memory partway through. Trim your video down to a few seconds beforehand.
The fixed 10 frames per second means fast motion can look a little choppy compared with the original. That is the cost of keeping file sizes reasonable.
Because the output width is set to 480 pixels, a video that is smaller than that will be enlarged, which does not add detail. For very small sources, the GIF may look soft. If the file still seems too large for where you want to share it, a shorter clip is the most effective fix.
