Your files stay on your device
Nearly all PDF, image, video, text and calculator tools do the work inside your browser, so we never receive the file. The few tools that need our server, such as DNS checks, minifiers and AI tools, say so on the page.
Downloads you can verify
Every download says where it comes from. Files we host are checked before they go live and show a SHA-256 checksum, so you can confirm your copy is intact.
No account, no payment
Every tool works without signing up. An account is optional and only saves your favourites and history. Nothing on this site costs money.
