About ToolPeg

ToolPeg is a pegboard of small, fast tools for the things people look up every day: converting units, counting words, working out dates, making passwords and QR codes, and shrinking images.

Private by design

Every tool runs in your browser. Text you type and files you choose are processed on your device and never uploaded to us. The site is supported by ads; see our privacy policy.

Accuracy

Unit conversions use exact legal definitions where they exist (1 inch = 2.54 cm, 1 pound = 0.45359237 kg), and every formula is covered by automated tests.
