Why QR codes still matter
QR codes are the fastest way to share a URL between devices — from desktop to phone, from a poster to a passerby, or from a business card to a contact. Since 2020, every modern phone camera reads QR natively. Perfect for sharing a wallpaper you found on your laptop with your phone in one scan.
Pro tips
- Keep contrast high — dark foreground on light background scans fastest.
- For business cards and print, generate at 1000×1000 or larger for print sharpness.
- Test the QR by scanning it before printing — some very short URLs may fail if the QR is too small.
Frequently asked questions
Do QR codes expire?
No. The URL is encoded directly into the pattern, so the code works forever — as long as the link itself stays live.
Are custom colors safe to use?
Yes, as long as you keep strong contrast — dark pattern on a light background. Scanners struggle with light-on-dark or low-contrast combinations.
What can I encode besides URLs?
Plain text, phone numbers, email addresses — anything under about 2,000 characters. URLs are the most common because every phone camera opens them instantly.
