Resize Video

Change a video’s resolution in your browser — no upload, no watermark.

How it works

  1. Select a video — it stays on your device.
  2. Pick a target resolution (1080p, 720p, 480p or 360p).
  3. Click Resize — the video is rescaled in your browser, keeping its aspect ratio.
  4. Your resized MP4 downloads automatically.

Frequently asked questions

Is my video uploaded anywhere?
No. Resizing runs entirely in your browser with ffmpeg.wasm; the file never leaves your device.
Will it stay in proportion?
Yes. Width is scaled automatically to preserve the original aspect ratio at your chosen height.
What format do I get back?
A standard MP4 (H.264/AAC) that plays everywhere. Larger clips take longer since processing happens on your device.
