Rotate & Flip Video

Rotate a video 90, 180 or 270 degrees or mirror it, with an instant no-quality-loss option for MP4 and MOV.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Rotate & Flip Video works

Lossless mode only changes the rotation flag in the file. Otherwise the picture is turned and re-encoded. Video work runs in ffmpeg.wasm, the FFmpeg toolkit compiled to WebAssembly (GPL build, loaded as a separate engine file of about 30 MB the first time, then cached).

Input: MP4, MOV, WEBM, MKV, AVI. Output: MP4, MOV.

How to use Rotate & Flip Video

1. Drop a video onto Rotate & Flip Video.
2. The first run downloads the ffmpeg engine (about 30 MB, once).
3. Set your range, format or quality options.
4. Process it (progress is shown live), then download.

Tips

• Shorter clips and lower resolutions process much faster.
• Processing speed depends on your CPU; plug in laptops for long jobs.
• Keep the tab in the foreground while encoding.

Rotate & Flip Video FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
