Questions
Does Video Compressor upload my video?
No. Videos are compressed locally in your browser tab and are never uploaded to Utilumo.
Why is the compressed video not always smaller?
Some inputs are already efficient. Output size depends on source codec, motion, resolution, selected quality, and browser encoder behavior.
Can I remove audio while compressing?
Yes. Turn on Mute output before exporting to discard audio tracks in the compressed MP4.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
