About Toolito
Last updated:
Little tools, big results. Toolito is a self-service laundromat for files: drop your images and PDFs in a machine and take them home lighter, converted, folded or sorted. Every machine is free, day or night.
Four of the five machines run entirely on your device, so your files never leave it. Only the dryer, which compresses PDFs, uses our server — and it empties itself after every load. The details are in the Privacy Policy.
Built with open source
Toolito stands on the work of many open-source projects. Thank you.
