# About Converterrr

> Converterrr makes file conversion fast, private and pleasant. Most conversions run in the browser, so files never leave the device.

Modern browsers can run the same engines as professional tools through WebAssembly and WebCodecs. Converterrr packages them into one converter for images, video, audio, documents, eBooks, spreadsheets, presentations, archives and fonts. When a conversion genuinely needs a server, it runs in an isolated sandbox that exists only for that job, and the result is deleted on a published schedule. Developers get the same engines through an API.

## Principles

- **Private by default.** If a file can be converted on the device, it is. The cloud is only used when the browser can't do the job, and the user is told when that happens.
- **Delete, don't hoard.** Files are kept only as long as needed to download them, then deleted automatically.
- **Honest pricing.** Browser conversions are free; credits pay for cloud work, and the cost is shown before it's spent.
- **Built on open source.** FFmpeg, libvips, ImageMagick, Pandoc, LibreOffice and others do the heavy lifting.
- **Calm software.** No ads, no pop-ups, no dark patterns.
