About this tool
Videos shot with the phone lying sideways land on computers and TVs rotated the wrong way, and some older camcorders even record upside down. No desktop editor is needed for this: the tool offers rotate 90° right, rotate 90° left, rotate 180°, horizontal mirror and vertical mirror - pick one and get a correctly oriented, universal MP4.
An honest note: rotating a picture means rearranging every pixel, which requires decoding and re-encoding. The shortcut some tools use - writing rotation metadata only - is frequently ignored by chat apps, web players and TV boxes, so the video looks straight on your phone but sideways everywhere else. This tool does the real rotation, so the result is correct on every device; encoding runs at CRF 20, visually very close to the source.
Everything happens locally in your browser: the video is never uploaded. After a 90° turn the frame dimensions swap (width becomes height) - pair with the Video Compressor afterwards if you also need a smaller file.

How to use

Frequently asked questions
- Why does rotating have to re-encode the video?
- Rotation rearranges pixels, which requires decode plus re-encode. The metadata-only shortcut some tools use is ignored by many players, chat apps and TV boxes - the video looks right on your phone but stays crooked everywhere else. This tool performs true rotation so the file is correct on every device.
- Is there a quality loss?
- Re-encoding uses CRF 20, visually very close to the source at normal viewing. High-bitrate camera originals may even end up noticeably smaller, which is normal.
- Which option fixes my sideways phone video?
- Play the preview: if the image needs to turn clockwise to look upright, choose 90° right; counter-clockwise means 90° left; upside-down means 180°. Unsure? Rotate once and check the preview - each run is quick enough to try again.
- Which formats work, and is my video uploaded?
- MP4, MOV, MKV, AVI, WebM and other common videos are accepted; output is MP4. Nothing is uploaded: processing runs entirely in your browser memory after a one-time ~31 MB engine download that is cached for offline use.
