Video to GIF

Convert video clips into animated GIFs in the browser with trimming, size, and frame-rate controls, keeping source files on your device.

How to Use

  1. Select the video file to convert
  2. Adjust FPS and width if needed
  3. Click "Convert to GIF" button
  4. The GIF image will be downloaded automatically
  5. Verify the output file in your device's download folder.
  6. You can adjust settings and process new files immediately without any restrictions.

All processing is done in your browser, and files are never sent to a server.

Frequently Asked Questions

GIF conversion is memory-intensive. If it fails: (1) keep the source clip under 30 seconds and 100MB, (2) lower the FPS setting, (3) reduce the output width, (4) refresh the page and retry.
