Your selected video is processed in this browser tab. It is not uploaded to a conversion server.
Ready.
Privacy-first compression
Many video compressors require an upload. This page is designed around the opposite expectation: process the selected file locally and be honest about browser limits.
Best settings and limits
Best first try
Balanced at 720p is the safest first pass. Use stronger compression when the file must be much smaller.
When this may fail
Local processing depends on browser memory and CPU. Large files can fail even though no upload is happening.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
Frequently asked questions
What makes this compressor private?
The video you choose is processed inside the browser tab instead of being uploaded to a server.
Is this the same engine as the main compressor?
Yes. This page serves the privacy-focused search intent using the same compression capability.
Can I use it for sensitive files?
The tool is designed to avoid uploads, but you should still use your own judgment about device and browser security.
