How to share and print a QR code

A QR code is just an image, so sharing it is easy — the trick is keeping it crisp and high-contrast so it scans every time, on screen and on paper.

Share it digitally

1. In Scan QR Code Master, open the code under My Codes and tap Share.
2. Send it through Messages, email, or any app, or save it to Photos.
3. Drop it into a slide, social post, or email signature at a size where the squares stay sharp.

Print it so it always scans

• Export at high resolution — a blurry or pixelated print won't read.
• Keep a white 'quiet zone' margin around the code; don't crop it tight.
• Print dark-on-light with strong contrast; avoid busy backgrounds behind it.
• Size for distance — bigger for posters, and always test the final print with a phone.
