Printing & Quality Guidelines
Follow these ISO/IEC 18004 recommendations to ensure instant, frictionless scans:
Maintain strong contrast: ensure dark foreground elements on a clean light background.
Observe the Quiet Zone: leave at least 4 modules of blank white margin around the QR code.
Test before bulk printing: scan the physical printed sample on both iOS Camera and Android Google Lens.
Use vector SVG for print production: SVG scales infinitely without pixelation on large signage or menus.
100% Client-Side Privacy Guarantee
QR Studio never stores, tracks, or analyzes your input payload. All matrix math, Reed-Solomon error correction encoding, and image rendering occur directly in your browser.
Frequently Asked Questions
How much text can I fit inside a single QR code?›
Standard QR codes can store up to 7,089 numeric characters or 4,296 alphanumeric characters (or approximately 2,953 bytes of UTF-8 text) at low error correction. However, for fast scanning with smartphone cameras, we recommend keeping text under 500 characters.
Does scanning a text QR code require internet access?›
No. The entire message is stored within the code itself. The scanner decodes the message instantly in complete offline mode without sending any requests over the internet.
What happens when someone scans a plain text QR code?›
Most smartphone cameras will display the text in a banner card with a "Copy Text" button. Specialized barcode scanners will type the characters into whatever software application currently has cursor focus (keyboard wedge emulation).
Can I include special characters or symbols?›
Yes! QR Studio supports full UTF-8 character encoding, including symbols, accents, and non-Latin scripts (such as Hindi, Arabic, Japanese, or Cyrillic).
