Tools that don't phone home.

218+ utilities · 10 categories · built for the browser you already have open

Toolkit Pro started from a simple annoyance: most "free online tools" quietly upload your text or image to a server before doing anything with it — and a growing number now route that request through an AI model you never asked for, just to resize a picture or format some JSON. We built the opposite. Every one of the 218+ tools here runs as plain JavaScript, in the tab you're already looking at, using nothing more exotic than the math, string, canvas and cryptography APIs your browser ships with.

What's inside

The toolkit is split into four bins, 25 tools each: Text & Writing (counters, converters, ciphers, diff checkers), Image & Design (resizing, cropping, filters, palette and CSS generators), Calculators & Converters (EMI, BMI, unit and date math), and Dev Tools (JSON, regex, hashing, encoding, and other everyday developer utilities).

Why "no AI" is the point, not a limitation

Formatting JSON or resizing an image doesn't need a language model — it needs correct code. Doing it with plain JavaScript instead means the result is instant (no round trip to an inference server), works offline once the page is loaded, costs us nothing to scale, and — most importantly — never leaves your device. We think that's a better default for a utility site, not a compromise.

How we keep the lights on

Toolkit Pro is free to use, with no paywalled tools and no account wall. The site is supported by advertising rather than subscriptions, which is why you may see ad placements around the tools. See our Privacy Policy for details on how those ads work.
