Output sizes are estimates. Vidsize tries to stay under your target; results can vary.

The number shown before compression is an estimate, not a promise. Some targets may be unreachable, and a finished file can still exceed the target.

Private by design

Compression happens on your device without uploading your video or creating an account. It works offline, and the original file is not deleted. Ads and the optional rewarded ad require a connection.
