QR Generator

What is QR Generator?

Generate QR codes for URLs, plain text, Wi-Fi credentials, contact cards, and any string up to about 2k characters. Choose foreground + background colours and error-correction level, live preview updates as you adjust. Download as PNG for print or screen use. Running entirely in your browser means the QR data never leaves your device.

Common use cases for QR Generator

• Printing a Wi-Fi QR code for a café or co-working space.
• Embedding a vCard in a business-card design.
• Linking a restaurant menu PDF from a table sticker.
• Auto-opening an Instagram profile from a poster.
• Sharing an event RSVP URL on printed invites.

Common pitfalls and how to avoid them

• Scanner cannot read the code — Increase the module size (print larger) or bump error-correction to "High" to survive surface damage and reflection.
• Logo obscures the data — Keep the logo to ≤20% of the total area and use error-correction level Q or H so the reader can reconstruct missing modules.
• Wi-Fi QR does not auto-join — Check the format string: WIFI:T:WPA;S:<name>;P:<pass>;;. iOS 16+ and Android both honour this when the camera scans it.

When should I use QR Generator?

QR Generator creates new codes. To read an existing QR code (from image or camera), use QR Scanner. For barcodes (EAN, UPC, Code128), use Barcode Generator.
