Make an MP4 smaller
Bring the size of an MP4 down without turning it into something else. The video is re-encoded at a higher compression level and you decide how hard.

Frequently asked questions
How much smaller will it get?
It depends entirely on what the original was. Footage straight off a phone or a screen recorder is usually carrying a lot of waste and can lose half its size or more with nothing visible changing. Something already compressed once has much less to give, and pushing it harder shows.
What happens to the quality?
Anything that re-encodes the video costs a little quality, and this page tells you when it does. Trimming on a keyframe and removing the sound do not re-encode at all, so those come out identical to the original.
Is anything uploaded?
No. The video engine runs inside your browser, so your files are read on your device and never leave it. There is no account, no upload and no watermark.
Is it really free?
Yes. No sign-up, no trial, no watermark and no limit on how many videos you put through it. The site is paid for by ads.
