About MARZ.tools

MARZ.tools is a free directory of 122+ small, single-purpose tools spanning 9 categories — calculators, developer utilities, text and content tools, SEO helpers, crypto/DeFi math, and AI prompt tools, with image and document tools on the way.

Every tool is built to run entirely in your browser. There's no account to create, no file upload to a server, and no usage limit — you open a tool and it works, using your device's own processing power instead of ours.

The site is supported by ads rather than subscriptions, which is what keeps every tool free with no caps. We keep ad placements out of the way of the tool itself, and none of them run above the fold.

MARZ.tools is actively growing — new tools are added regularly. If there's a tool you'd like to see, or something on the site that doesn't work the way it should, we'd like to hear about it on the contact page.
