About toolcan

toolcan is a growing collection of 546 practical online tools, calculators, converters, generators, and everyday utilities, gathered into one tidy nest. The goal is simple: when you need a quick answer, the tool should load instantly, do the job, and get out of your way.

Built client-side first

Wherever it's possible, every tool runs entirely in your browser. Your inputs are processed on your own device and never uploaded. That choice keeps three promises at once:

• Private, what you type stays with you. Nothing is sent to a server.
• Fast, there's no round-trip to a backend, so results are instant.
• Reliable, no servers or databases to break, so tools just keep working.

toolcan stands on open-source software such as PDF.js, pdf-lib, qpdf, and SheetJS. The open-source licenses page lists every component and its license.

What you won't find here

• No accounts or sign-ups.
• No uploading your data to “process” it, tools run in your browser.
• No tracking by us, we keep only an anonymous per-tool open count.

How it stays free

toolcan is free to use, with no paywalls. The website shows no ads today and sets no ad cookies. If that changes, our privacy page will say so first.

A note on accuracy

Our tools aim to be correct and genuinely useful, but results are estimates and shouldn't be treated as financial, legal, or medical advice. For anything important, double-check the numbers with a qualified professional.

Trademarks

Excel, Photoshop, Windows, PowerShell, Visual Studio Code, macOS, IBM i, AS/400, Docker, Git, Linux, and QR Code are trademarks of their respective owners. toolcan isn't affiliated with or endorsed by them; the names appear only to describe what a tool or cheat sheet covers.
