MP4 Compressor, answered.

How do I compress an MP4 file? +

Upload above, review the predicted size for each of three quality levels, pick, download. Re-encoding uses H.264 + AAC, so the result plays everywhere the original did.

How much smaller will my MP4 get? +

Phone and screen recordings typically shrink 60–85% at level 2 with little visible difference. The prediction shows your exact numbers before you commit.

Does compressing reduce resolution? +

Not unless necessary — bitrate drops first; resolution steps down only at aggressive levels where keeping it would look worse.

Is there a file size limit? +

Multi-GB files are fine — processing runs server-side in a queue, and failed jobs are never billed.
