The complete guide to QR Code Generator
Last updated June 1, 2026QR codes encode text, URLs, contact information, Wi-Fi credentials, and other data into a scannable 2D matrix. Convertify's QR Code Generator creates high-resolution QR codes that download as PNG or SVG, with customization options for size, error correction level, foreground color, and background color — without any sign-up or API key.
Error correction in QR codes is a critical setting often overlooked: it determines how much of the QR code can be damaged or obscured while still scanning correctly. Higher error correction (Level H) makes the code more damage-tolerant but larger. For codes printed on paper, Level M is standard. For codes that will be partially covered by a logo, use Level H.

Step-by-step: how to use QR Code Generator
- 1
Enter the content
Type or paste a URL, phone number, email address, plain text, or any string up to ~4,000 characters. For URLs, include the full address including https://.
- 2
Customize (optional)
Set size (pixels for PNG, or scalable for SVG), foreground color, background color, and error correction level (L/M/Q/H). A live preview updates as you type.

Download
Download as PNG (for printing, presentations, websites) or SVG (for scalable, print-quality use in InDesign, Illustrator, or Figma).
Real-world scenarios
Restaurant and bar menus
A QR code linking to a PDF menu or online ordering system goes on table cards and window decals. Download as SVG for crisp printing at any size, colored to match your brand.
Business cards and marketing materials
Encode a contact vCard (name, phone, email, company) so scanning the QR code adds the person to contacts automatically. Or link to a LinkedIn profile or website — a single scan is faster than manual typing.
Wi-Fi guest access
Encode Wi-Fi credentials (SSID, password, encryption type) as a QR code posted in a guest room or office lobby. Guests scan and connect without typing a complex WPA2 password.
Event tickets and access control
Generate unique QR codes per ticket (each encoding a unique ticket ID) for event entry systems. Download in batch (URL + ticket number appended) and print on tickets.
Troubleshooting and edge cases
My QR code isn't scanning.⌄
Common causes: (1) Too high a data density — try shortening the URL with a link shortener (bit.ly, t.ly). (2) Error correction too low combined with printing imperfections — switch to Level M or H. (3) Too small — QR codes need to be at least 2cm × 2cm for reliable scanning. (4) Low contrast — ensure high contrast between foreground and background (black on white is most reliable).
I want to put a logo in the center of the QR code.⌄
Set error correction to Level H (30% of modules can be damaged and the code still scans). Place the logo over the center at no more than 30% of the code's area. The error correction compensates for the obscured modules.
The QR code PNG looks pixelated when printed.⌄
PNG is resolution-dependent. Use the SVG download format for print materials — it scales to any size without pixelation. In Photoshop/GIMP, use the PNG at 300+ DPI (choose 1200×1200px minimum for business card use).
