## What it does

Pick the exact clip with the trim handles, then balance quality against file size with the fps, width, palette and dithering controls. GIF grows fast — 480px wide at 10 fps is the sweet spot for most clips — and the size readout updates every run so you can tune it until it's right.

Everything — demuxing, decoding, scaling, encoding — runs inside your browser using the hardware-accelerated WebCodecs API. Nothing is installed and nothing is uploaded.

## Limits

Does not download videos from websites and does not convert between video codecs.

## FAQ

### Why is there no file size limit or queue?

Because there is no server involved. Upload-based converters shuttle your video to their machines, so they meter and queue you. Here the conversion runs on your own hardware — a 500 MB video starts converting the instant you drop it.

### What happens to the audio track?

GIF has no sound, so the audio track is simply dropped. The tool reminds you of this on every conversion.

### Is my video uploaded to a server?

No — and you can verify it. Open your browser's DevTools Network tab while converting: there is no upload request, because the pipeline (decode, resize, encode) runs entirely on your machine via the WebCodecs API. Our servers cannot see your files; there is no upload path to send them through.

### Is there a watermark or a file size limit?

No watermark, ever. There's no hard file size limit either — a single conversion is capped at 60 seconds of video to keep memory in check, and you can trim a long video into ranges.

### Why is this faster than online converters for big files?

Upload-based converters spend most of their time transferring your file and waiting in a queue. Here a 100 MB video starts converting immediately, using your browser's hardware-accelerated video codecs.

### Which browsers are supported?

Any browser with the WebCodecs API: recent Chrome, Edge, Safari and Firefox. If H.264 encoding isn't available, the tool automatically falls back to the royalty-free VP9 codec in a WebM file and tells you.
