Rotate or flip a video — perfect for fixing footage shot sideways or upside down on a phone. Runs entirely in your browser.

Optimize for your platform

工作原理

Phones sometimes save video with the wrong orientation, leaving it sideways or upside down. This rotates or flips the actual frames with FFmpeg in your browser.

  1. 1
    FFmpeg.wasm loads once
    The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is cached afterwards.
  2. 2
    You pick a rotation
    90° left/right, 180°, or mirror horizontally/vertically — with a live CSS preview so you can confirm before processing.
  3. 3
    FFmpeg transposes the frames
    The transpose/flip filter re-orients every frame; the audio is copied through untouched.
  4. 4
    You download the fixed video
    The correctly-oriented MP4 is offered for download and previewed in-page.

Fix a sideways clip without uploading it — the rotation happens entirely on your device.
