Most everyday computer jobs don’t need a download or an account. Making a QR code for a flyer, counting the words in an essay, or creating a strong password takes a few seconds when the right tool is already in your browser.

That is the idea behind PotatoTools, a free collection of simple online tools and calculators. You open a tool, use it, and get back to work. No sign up is needed.

What you can do with it

• Turn a link, WiFi network or contact card into a scannable code with the free QR code generator, then download it as PNG or SVG.
• Create a strong random password in one click.
• Count the words and characters in your writing.
• Test your typing speed and track your progress.
• Work out an exact age, or convert height between feet and centimeters.
• Crop images, or convert CSV files to JSON for data work.

Because the tools run in your browser, there is nothing to install or update. The QR code generator, for example, builds codes on the page itself, with no account and no scan tracking.

Who it is for

Students checking an assignment’s word count. Teachers putting a QR code on a handout. Small business owners making a menu or event flyer. Developers who need a quick data conversion without opening a code editor.

If you often search for a quick tool to finish one small task, bookmark PotatoTools and keep it one tab away.
