About Abzario

Abzario was built with one simple goal: small everyday tasks — working out a percentage or an investment return, counting words, generating a QR code — should never require installing software or creating an account.

There are currently 71 tools across 17 categories, and the list keeps growing. Every tool is responsive, mobile friendly and available in both light and dark mode.
