qr code generator

How to use the qr code generator

  1. Paste the URL, text, Wi-Fi credentials, vCard, or other content the QR code should encode.
  2. Pick a size and error-correction level: L (7%), M (15%), Q (25%), H (30%). Higher correction lets the code survive damage, partial obscuring, or a logo overlay.
  3. Customize colors and (optionally) drop a center logo for branded codes — works because of the high error-correction tolerance.
  4. Preview the QR code, then download as SVG (scalable, sharp at any size) or PNG (universal raster format).
  5. Test scan with your phone camera before printing 1,000 of them.

When to use it

Use it for restaurant menus, event check-ins, business cards, Wi-Fi sharing, app-store links from posters, or any short URL that's faster scanned than typed. Alternative: many phones have built-in QR generators (iOS Shortcuts, Android Quick Settings); this tool wins for branded codes with logos and color customization.

Frequently asked questions

What is a QR code?
A 2D barcode that encodes up to 4,296 alphanumeric characters in a square matrix of black and white modules. Camera apps decode them in milliseconds. Invented in 1994 for automotive parts tracking, now ubiquitous for sharing URLs and contact info.
How much can a QR code hold?
Up to 7,089 numeric digits, 4,296 alphanumeric characters, or 2,953 bytes — but readability drops at high density. For short URLs and Wi-Fi credentials, the code stays compact and scans reliably.
What error-correction level should I use?
L (7%) for code shown on a clean digital screen. M (15%) for printed material that won't be touched. Q (25%) or H (30%) for codes that may get scratched, partially obscured, or include a center logo.
Can I add my logo to a QR code?
Yes — pick H-level error correction and overlay a logo up to ~25% of the code's area. The remaining error-correction headroom keeps it scannable. Use SVG download for crisp logo placement.
Why doesn't my QR code scan?
Common causes: too small (< 2 cm × 2 cm at typical reading distance), low contrast, blurred during printing, or content too long. The generator preview matches the actual scan target — test with a phone before mass-printing.
Are QR codes secure?
QR codes are dumb pipes — they encode whatever URL you give them. Phishing QR codes ("quishing") are a real threat. Always check the URL preview your phone shows before tapping through, especially for codes in public places.
