About Mavlo

A tool should do one job well, load quickly on any phone and ask for nothing in return. There are no accounts, no watermarks and no daily limits.

Whenever it is technically possible, the work happens inside your browser. That is why you can compress a photo or merge a contract without uploading it to someone else's server.

Each tool comes with a written explanation of how it works, worked examples and answers to common questions, so you can check the result instead of trusting it blindly. Calculators use exact calendar and unit definitions rather than rough approximations.

If you find a mistake, a missing unit or an idea for a new tool, we would like to hear about it.

The site is free to use. We may display advertising in the future to cover running costs. If we do, ads will be clearly labelled, will never sit above the tool, and this site will explain how they work in the privacy and cookie policies.
