MP4 Compressor
Shrink an MP4 so it fits email, chat or a slow upload. No account, no watermark.
The download link expires 1 hour after you download. Nothing is added to your file.
Drop an MP4 (up to 100 MB) and get a smaller MP4 back. On Balanced, a 60.6 MB 1080p MP4 at phone-camera bitrate (an animated test film) came out at 9.5 MB, 84% smaller, same resolution. Pick a size to fit under, 10, 25 or 50 MB. No account, no watermark.
Why use MP4 Compressor?
Fits where you need it
Fit under 10 MB for a chat app, 25 MB for an email attachment, or 50 MB. We size the bitrate from the video's length.
Stays an MP4
The result is an H.264 MP4 with AAC sound that plays on phones, browsers, TVs and in every editor.
Then get the words
Turn the same MP4 into a transcript in one click. The first 30 minutes are free.
