About this tool
Phones record sideways videos with a rotation flag that some players honor and others ignore, which is why a clip can look right on your phone and wrong on a PC. This tool rotates the actual frames and writes a normal MP4, so it plays the right way up everywhere. Mirroring fixes front-camera recordings that came out reversed.
How to use it
- Drop your MP4, MOV, WebM or MKV file into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click the button and wait a moment.
- Download the result.
Questions
