Frequently Asked Questions

Everything you need to know about universal in-browser video transcoding.

Yes! Apple iPhones record video in QuickTime MOV format by default. You can drag and drop your MOV file into Vexelloom, select MP4, and download a universally compatible MP4 video in seconds.

Yes! Select GIF as your target format. You can use the trimming controls to capture the exact funny or memorable moment, adjust the speed (e.g. 1.5x or 0.5x), and even enable Reverse or Boomerang effects.

No. Because Vexelloom operates locally in your web browser using HTML5 Canvas and WebAssembly rather than running on paid remote servers, there are zero file size limits, no daily conversion caps, and no subscriptions.
