A growing library of free, browser-based utilities for everyday tasks — built for everyone, from developers to construction workers.
Our mission
“Fast, free tools that respect your time and your privacy.”
The web is full of tool sites that make you sign up, show you ads, or upload your files to a third-party server. Handy Online Tools does none of those things. Every calculation, conversion, and generation happens locally — in your own browser tab.
How we work
Private by design
Every tool runs entirely in your browser. The data you enter — files, numbers, text — never leaves your device.
No friction
No account, no email, no paywall. Open the page, use the tool, close the tab. That's it.
Works everywhere
Fully responsive and installable as a Progressive Web App on desktop, iOS, and Android — works offline too.
Free, forever
Handy Online Tools will always be free. It's a utility site, not a subscription product.
What’s available
Age, loan, GST, percentage, paint, bricks
Weight, temperature, unit, URL, length
Brick & mortar, paint coverage, measurements
Hash, Unix timestamp, URL encoder/decoder
Word to PDF, text case conversion
QR codes, checksums, and more
Built with
Handy Online Tools is built with Next.js, styled with Tailwind CSS and DaisyUI, and installable as a Progressive Web App (PWA). We use a single privacy-respecting analytics signal for page views — see the Privacy Policy for details.
