Compress MP4 files

MP4 is the most common video format, and also one of the heaviest when exported at high bitrate. CompressEasy Desktop re-encodes your MP4 files to a smaller, still-sharp MP4 — locally, in batches, with nothing uploaded.

Use the free CompressEasy Desktop app for macOS and Windows to compress MP4 offline.

Available in the free desktop app

Video, PDF and PowerPoint compression run fully offline in the CompressEasy desktop app for Windows and macOS — no uploads and no file-size limits.

How it works

  1. Open CompressEasy Desktop and drag your MP4 files in.
  2. Choose High quality, Balanced or Maximum compression.
  3. Save the optimized MP4 wherever you want.

Smaller MP4, same playback

A high-bitrate MP4 carries far more data than the eye needs. Re-encoding at an optimized CRF keeps playback smooth while cutting file size substantially.

Optional resolution downscale

For very large clips, the Balanced and Maximum presets can cap resolution (e.g. to 1080p or 720p) for even smaller files when full resolution is not needed.

Local and unlimited with Pro

Compress as many MP4s as you like in the desktop app. The free plan covers everyday use; Pro removes the daily limit for heavy batches.

Frequently asked questions

Will the compressed MP4 play everywhere?

Yes. Output uses H.264 video and AAC audio in an MP4 container, which plays on virtually every device and platform.

Can I compress several MP4s at once?

Yes. Drop a whole batch and the app processes them one after another automatically.

Is it really offline?

Yes. FFmpeg is bundled in the app, so MP4 compression runs entirely on your computer with no upload.
