Frequently asked questions
How much smaller will my video get?
It depends on how the original was encoded — screen recordings and phone videos often shrink 50–90%. The compressor re-encodes with tuned H.264 (MP4) or VP9 (WebM) presets; pick High for near-original quality, Standard for the best balance, or Small for the smallest file.
Is my video private?
Compression is real re-encoding work, so it runs as an isolated server job over TLS and your files — input and output — are deleted automatically after processing. Nothing is shared or retained beyond your workspace retention window.
What are the limits?
Videos up to 20 minutes. Upload size follows your plan: 10MB on free accounts, 100MB on Pro, and 500MB on Enterprise. A one-time Week Pass also unlocks the 100MB limit for 7 days.
Which output format should I pick?
MP4 (H.264) plays everywhere and is the safe default. WebM (VP9) usually compresses slightly better at the same quality and is great for the web, but older devices may not play it.
Only need part of the video? The lossless trimmer cuts without re-encoding — or add AI subtitles.
