Why this tool is useful
Reduce a short video's transfer size with an explicit bitrate instead of an unexplained quality slider.

Private Video Compressor
Re-encode a browser-decodable clip to a selected WebM video bitrate 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
MediaRecorder receives the local canvas stream and applies the selected target bitrate; the report compares input and output bytes.
Practical example
Re-encode a short presentation clip at 1 Mbps, compare its byte size with the source and download 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.
