Private Video Rotator
Rotate a browser-decodable clip by a right angle and export WebM without uploading the source video.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
A bounded canvas swaps dimensions when needed, rotates its drawing context around the center and records transformed frames locally.
Practical example
Rotate a portrait clip 90 degrees clockwise, check the swapped dimensions and save the WebM result.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
