How to Compress an MP4 — 4 Steps
Our compressor uses FFmpeg with H.264 encoding to reduce file size while keeping the video sharp and watchable.
Upload your MP4 or video file
Select your video up to 100 MB. MP4, MOV, WebM, MKV, and AVI are all accepted.
Choose a compression preset
Use Balanced for the best quality-to-size ratio (recommended), Fast for maximum size reduction, or Quality for near-lossless output.
Confirm and compress
Check the authorization box and click Compress MP4. Processing time depends on file length and preset.

Frequently Asked Questions
How much will my MP4 be compressed?
Typical results are 40–70% size reduction on the Balanced preset. The exact saving depends on your source codec and bitrate.
What is the output format after compression?
All presets output MP4 with H.264 video and AAC audio — the most universally compatible container for uploading anywhere.
Which preset should I use for YouTube or TikTok uploads?
Use Balanced for the best quality-to-size ratio. Most upload size limits on YouTube (256 GB), TikTok (287 MB), and Instagram (650 MB) are generous enough that Balanced is sufficient.
Will compression affect video resolution?
No. The Balanced and Quality presets preserve your original resolution. Only the bitrate is adjusted to reduce file size.
What is the maximum file size for compression?
The maximum upload size is 100 MB and the maximum duration is 10 minutes.
