Privacy policy

Last updated September 6, 2026

The short version

Your video is never uploaded, never stored and never seen by anyone but you — compression happens inside your browser. The site does count page views using a cookieless analytics service, which sees which page you looked at but nothing about your file. There are no accounts, no advertising and no data sold to anyone.

Your video files

When you select a video, your browser reads it from disk into its own memory and passes it to FFmpeg compiled to WebAssembly, which runs inside the page. The compressed result is produced in that same memory and offered back to you as a download.

No part of your video is transmitted over the network. This site has no upload endpoint and no storage to receive it. Nothing about the file — its name, size, duration, contents, or the settings you chose — is recorded, logged or transmitted. When you close or reload the tab, the in-memory copy is discarded.

You can verify this yourself: open your browser's developer tools, switch to the Network tab, and compress a file. You will see the site's own assets and the FFmpeg WebAssembly binary being fetched, and no request carrying your video.

Analytics

The site loads a cookieless analytics script from api.panalytics.money, an analytics service I run myself on my own server, so I can see whether anybody is using the tool and which guides are worth writing more of. No analytics company is involved and the counts are not shared with anyone.

What it records

  • The page URL you visited
  • The referring site, if any
  • An approximate country
  • Browser and device class
  • Aggregate counts of the above

What it does not do

  • Set cookies
  • Build a cross-site profile of you
  • See anything inside the compressor
  • See your file, its name or its size
  • Sell or share data with advertisers

If you would rather not be counted, any content blocker or your browser's tracking protection will stop the script, and the compressor works exactly the same without it. Nothing on this site depends on analytics loading.

Cookies and local storage

This site sets no cookies of its own and requires none to function. Your browser will cache the site's files and the roughly 30 MB FFmpeg WebAssembly binary in its normal HTTP cache so the second visit is fast — that is ordinary browser caching, it stays on your device, and clearing your browsing data removes it.

Server logs

The site is a static file server behind a reverse proxy. Like any web server it processes the usual request metadata — IP address, requested path, user agent — in order to answer requests. These are not used to build profiles, are not combined with anything else, and are not shared. No request ever contains video data, because your video is never sent.

Third parties

The site makes no third-party requests at all. The only request that leaves this domain goes to api.panalytics.money for the analytics script described above, and that server is mine too. Every other asset — the FFmpeg WebAssembly cores included — is served from this domain, which is also required by the cross-origin isolation headers the tool needs. There is no advertising network, no tag manager, no session recorder and no A/B testing service.

Children

The site is not directed at children and collects no personal information from anyone, of any age.

Changes and contact

If this policy changes, the date at the top of the page changes with it. The site is operated by Kyllian — see the about page for who that is and how to get in touch.
