Compress an MP4 Online
To compress an MP4 online, upload the file here, select high, medium or low quality, and download the smaller MP4 — the entire job runs in your browser, on any device, with nothing to download or install. One video costs one credit, and new accounts get three for free.
MP4 is the most common video container, but the size of an MP4 depends entirely on how it was encoded — two files with identical content can differ tenfold. Re-encoding at a controlled quality level reclaims that wasted space while keeping the video in the same universally compatible format.
How it works
- 1
Upload your MP4
Select or drag in the file, up to 500 MB. Other formats like MOV or MKV are accepted too, so you do not need to convert anything beforehand.
- 2
Choose high, medium or low
High preserves near-original quality, Medium balances size against sharpness, and Low produces the smallest file. Pick based on where the video is going.
- 3
Download the smaller MP4
Processing finishes in the cloud and your compressed file is ready to save. The result plays anywhere the original did — same format, lighter weight.

Frequently asked questions
How does MP4 compression actually work?›
The video inside your MP4 is re-encoded at a lower bitrate, meaning fewer bits are spent per second of footage. Modern encoders spend those bits intelligently, so a well-compressed file can look nearly identical at a fraction of the size. The container stays MP4, so compatibility with players, phones and websites is unchanged.
Is there a file size limit for uploads?›
Yes, 500 MB per file — large enough for most everyday MP4s, including lengthy screen recordings and phone footage. If your file exceeds that, trim it into sections first or reduce its resolution, then compress each part. The 500 MB ceiling applies per upload, not per account.
Is this MP4 compressor really free?›
Creating an account gives you 3 free credits, and compressing one MP4 costs 1 credit — so your first three files cost nothing. After that you can buy a one-time credit pack on the pricing page whenever you need more. There is no subscription, trial countdown or watermark trap.
Will compression change my MP4 format or resolution?›
No. The output is still an MP4 at the same resolution and frame rate — only the bitrate drops. If you want a different format, use the converter tool, and if you want smaller dimensions, the resize tool scales the video down. Combining resize plus compression yields the smallest possible files.
