Processing
Browser on your device

Step-by-step instructions

  1. Select video files.
  2. Set output format and maximum width.
  3. Wait for conversion and save the results.

Limits and considerations

GIF output uses the first 15 seconds at 10fps without audio. First-run download is about 32MB; processing is limited to 3 minutes per file. Support depends on the codec, not just the extension.

50MB per file · up to 20 files · 150MB total input. Available capacity depends on device memory and browser support.

What if video conversion takes too long?

Use Cancel to stop processing. Retry with a shorter or smaller video.
