Frequently Asked Questions
How much smaller will my video be?
Depends on the compression level. Light: 20-40% smaller. Balanced: 40-60% smaller. Maximum: 60-80% smaller. Results vary based on the source video.
Will there be quality loss?
Some quality reduction is inherent in compression. Light mode preserves the most quality. For most viewers, Balanced mode is visually indistinguishable from the original.
What output format is used?
The compressed video is saved as WebM format, which is supported by all modern browsers and most media players.
Is there a file size limit?
No hard limit, but very large videos (over 500MB) may be slow to process since everything runs in your browser.
