Why use SnagATool?

SnagATool is a collection of free online tools built for one purpose: helping you get small jobs done fast. Whether you are a freelancer creating an invoice, a student checking a word count, a bride planning a wedding budget, or a developer generating a QR code, there is a tool here that does exactly what you need — and nothing you do not.

Every tool on this site runs entirely in your web browser using JavaScript. That means your files, text, and numbers never leave your device. When you compress an image or count the words in a document, nothing is uploaded to a server, stored in a database, or shared with anyone. It is private by design, and it is also why the tools are so fast: there is no waiting on uploads or server queues.

There is no account to create and nothing to install. The tools work on phones, tablets, and desktop computers, and they are free to use as often as you like. We keep the lights on with advertising, which is why you will see a few clearly labeled ad slots around the site — the tools themselves will always stay free.

Bookmark this page and come back whenever you need a quick calculator, converter, or generator. New tools are added regularly, so check back often.
