Privacy

There is no backend. No upload endpoint, no database, no analytics, no cookies, no account. Your files are opened by your browser and processed on your device.

Verify it yourself

Don't take this on trust. It takes about ten seconds to check, and the instructions work equally well on any site making the same claim.

  1. 1. Open your browser's developer tools and select the Network tab.
  2. 2. Open any tool on this site and run it on a file.
  3. 3. Watch the requests. Your file is not among them.

What does get requested

Being precise, because "nothing leaves your machine" deserves the fine print:

  • The page itself, its JavaScript, and the self-hosted fonts. All from this domain.
  • For the video and audio tools, the ffmpeg WebAssembly engine (about 31 MB), also from this domain. It is cached after the first use.
  • For Audio to text, the Whisper model weights (about 39 MB) are downloaded from the Hugging Face CDN on first use, then cached by your browser. This is the one request that goes to a third party, and it is a download of the model, never an upload of your audio.

What is stored on your device

One localStorage entry recording whether you prefer the light or dark theme. Nothing else, and it never leaves your browser.

The practical consequence

Because nothing is uploaded, the limit on file size is your device's memory rather than someone's upload cap. There is no queue, no daily allowance, and nothing to sign up for.
