About FastWebTools

What FastWebTools is

FastWebTools is a free collection of browser utilities at fastwebtools.net. Tools include PDF merge, split, and unlock; a unit converter; a document scanner; image conversion; a WCAG contrast checker; JSON to Excel; and a YouTube revenue estimator.

Where processing happens

Many tools run entirely in your browser: the unit converter, contrast checker, PDF to Word text export, JSON to Excel, YouTube revenue calculator, and document scanner. Some image and PDF workflows process files in ephemeral edge memory and do not keep permanent copies of your uploads.

Offline use

FastWebTools is an installable Progressive Web App (PWA). Client-side tools such as the unit converter continue to work without a network connection after the app shell has been cached.
