About Zentools

Zentools is a collection of free online tools built to be quick, clear and easy to use. We add new tools regularly, covering image editing, PDF utilities, calculators, unit converters, text utilities and developer tools.

What we care about

Tools should open fast, work on a phone, and do one job well. Where it is technically possible, files are processed in your browser and are not uploaded to our servers.

How we pay for it

Zentools is free to use and is supported by advertising. Ads help cover hosting and let us keep building new tools.
