PRIVACY

A video compressor that keeps your videos on your device

MP4 Compress is a privacy-first online video compressor. Nothing leaves your browser — here's exactly what that means.

Last updated: January 2025

What we collect

Almost nothing. We do not require an account, and we do not collect, store, or transmit your video files. Basic anonymous analytics (page views, browser type) help us improve the product.

How your videos are processed

All MP4 compression happens locally in your browser using WebAssembly. Your files never get uploaded to our servers or any third party. When you close the tab, the working files are discarded.

Tracking & cookies

We use a single, privacy-first analytics cookie to count unique visitors. No third-party advertising trackers, no fingerprinting, no cross-site profiling.

Third-party services

We use a privacy-respecting analytics provider and a global CDN to deliver this site quickly. Neither receives your video files — only standard web request metadata.

Your choices

You can disable cookies in your browser at any time without affecting compression functionality. You may also use the site in private/incognito mode.

Changes to this policy

If we ever materially change how we handle data, we will update this page and the date below. Continued use of MP4 Compress means you accept the latest version.
