Why use Toolzy?

Toolzy is a growing collection of free online tools built for speed and privacy. Most online tools upload your files to a remote server. Ours do the work directly in your web browser using modern JavaScript, so your PDFs, photos and text never leave your device.

Private by design

Merging a PDF, compressing an image or formatting JSON all happens on your own computer or phone. Nothing is uploaded, stored or shared, which makes the tools safe for confidential documents.

No sign up, no limits, no watermarks

Every tool is free to use as often as you like. There are no accounts, no daily limits and no watermarks on your files.

Works on any device

The tools work in Chrome, Safari, Edge and Firefox on Windows, Mac, Android and iPhone. Once a page has loaded, most tools keep working even if your connection drops.
