The classic phone-video accident
A video that plays sideways usually carries a rotation hint some players ignore. Instead of relying on metadata, this tool physically rotates every frame and writes a normal upright MP4 that plays correctly everywhere: old TVs, presentations, editing software.
Frequently asked questions
Which direction do I pick?
If heads point right, rotate 90° left. If heads point left, rotate 90° right. Upside down: 180°.
Does rotating lose quality?
One high-quality H.264 re-encode (CRF 23) happens; visually transparent for phone footage.
Is my video uploaded?
No. The rotation runs in your browser via WebAssembly FFmpeg.
Is there a limit on files or length?
No. Your own device does the work, so there are no queues, caps or accounts.
