Convert files without uploading them

How it works

  1. 1. Add your file

    Drag it in or pick it from your device.

  2. 2. Pick a format

    Choose what you want to convert it to.

  3. 3. Download

    Your browser does the work and gives you the new file.

Private by design

Conversions run on your own device with standard browser technology (Canvas, Web Workers and WebAssembly).

  • Your files are not uploaded to a Convertolo server.
  • File names and contents are never sent to analytics.
  • Some features do need the internet, for example checking a license key with our payment provider, Gumroad.
