Browser Workflow
Compress video for smaller sharing and upload
Files stay in your browser during processing. That makes the flow faster for students, office users and mobile visitors who want a direct tool on the same page.
The output is saved as MP4 with a smaller video bitrate. Browser compression can be slow for very large videos.

Choose your file and start the workflow.
Before you upload
Shrink screen recordings and assignment clips in the browser
Moodle, Google Classroom, and WhatsApp choke on 200MB phone screen recordings. This tool re-encodes in the browser for lighter sharing — not cinema-grade colour grading. Expect longer processing on old phones; plug in power for clips over a few minutes.
For official exam proctoring uploads, read the portal rules first. Some require original resolution — compression may disqualify the file even if size fits.
Works well for
Typical student and creator clips
- 10-minute lecture screen captures
- Demo videos for freelance clients on slow links
- Trimmed gameplay or tutorial drafts before YouTube upload
When not to use
Limits to know
- 4K wedding footage — use desktop editor
- Portals that forbid re-encoding
- Clips with DRM or protected streams
After compression
Play the full clip once before sending
Scrub to the middle and end — audio sync issues show up there first. If slides become unreadable, export a lower resolution from the source app instead of crushing bitrate further.
