About Helpje
Helpje is a collection of free online tools that run directly in your browser. File converters, calculators, generators and text tools — all in one place, with no registration and no installation.
Privacy first
Most of our tools process data locally — your files and text are not sent to any server. If a tool requires server-side processing, we always state that clearly.
Who is it for?
For anyone who needs to quickly calculate, convert or generate something — pupils, students, freelancers and small businesses.
