About these tools

UnitWiz, Scientific Calculator, Age Calculator, QR Maker, and Image Resizer are everyday tools for tasks that come up constantly. UnitWiz covers length, weight, temperature, speed, data size, and more across metric and imperial systems. The Scientific Calculator handles trigonometry, logarithms, powers, and roots with a running history. Age Calculator gives you exact years, months, and days to the day, plus your next birthday. QR Maker generates downloadable PNG codes for any URL, Wi-Fi network, email, or contact card.

Image Resizer deserves a special note: photos are resized and compressed entirely in your browser. Your images are never uploaded to a server at any point in the process.

Common questions

• Are my images uploaded when I resize them?
  No. Image resizing and compression happen locally using the browser's Canvas API. Your photos stay on your device throughout the process.
• What can the QR code encode?
  QR Maker supports URLs, Wi-Fi credentials (SSID, password, encryption type), email addresses with optional subject and body, and vCard contact information. The generated code can be downloaded as a PNG.
