Video Compressor
Shrink video files with H.264/VP9 compression right in your browser. Pick a platform (WhatsApp, Insta, YouTube Shorts…) or tune it yourself.
How Video Compressor works
MP4, MOV, WEBM, MKV, AVI — all supported. Nothing is uploaded.
High quality (CRF 20) → Balanced (26) → Small (30) → Very small (34).
Fits into WhatsApp's 16 MB limit, Gmail's 25 MB, and most upload portals.
Frequently asked
What is CRF?+
Constant Rate Factor — H.264's quality knob. Lower = better quality + larger file, higher = smaller file + more visible compression.
Will it work on my iPhone videos?+
Yes. MOV files from iPhones convert cleanly to compressed MP4 that plays everywhere.
How much smaller will my video be?+
Depends on source, but 50–90% reduction is typical. A 100 MB clip usually lands around 15–40 MB in Balanced mode.
