The FFmpeg engine (~25 MB) downloads on first use and is cached by your browser. The video is re-encoded to match the new resolution.

How to use

  1. Drop a video file or click to select an MP4, WebM, or MOV.
  2. Pick a resolution preset (720p is the default) or choose "Custom" and enter exact dimensions.
  3. Click "Resize video" and download the result.

Frequently asked questions

What resolution should I pick?

720p (1280×720) is the sweet spot for most uses — sharp on any screen, small file size. Pick 1080p for full-HD, or 480p/360p to shrink files for sharing.

Will quality drop when I resize a video?

Scaling down involves re-encoding so some quality loss is expected, but at 720p or higher on typical footage it is barely visible. Scaling up beyond the original resolution adds no real detail.

Can I make the video larger (upscale)?

Yes — enter custom dimensions larger than the original. However, upscaling stretches pixels and often looks blurry. Use it only when a specific resolution is required by a platform.

What is the maximum file size?

Up to 2 GB on desktop; mobile browsers may struggle above 500 MB. The video stays on your device — nothing is uploaded — so the limit is your device memory.
