Frequently Asked Questions

Do these QR codes expire?

No — these are static QR codes that permanently encode your data into the image. They work forever, as long as the link or content you encoded remains valid.

Can I put a logo in the center of the QR code?

Yes — use Error Correction Level H (30% tolerance) when adding a logo. This allows the logo to cover up to 30% of the code area while remaining scannable. Always test before printing.

What is the best error correction level to choose?

Level M (15%) for standard use. Level H (30%) if you plan to overlay a logo. Higher levels make the code denser — fine for digital, but harder to scan from a small printed size.

What is the difference between PNG and SVG output?

PNG is a fixed-resolution pixel image — best for web sharing and digital displays. SVG is infinitely scalable without quality loss — best for print (banners, posters, business cards). Always download SVG if you plan to print at large sizes.

Why does my QR code fail to scan?

Common causes: low contrast between foreground and background colors, code too small (under 2cm/0.8in when printed), the encoded URL is too long making the code overly dense, or a damaged/low-quality print.

Can I encode Wi-Fi credentials in a QR code?

Yes — switch to Wi-Fi mode, enter your network name (SSID) and password. When someone scans it, their phone automatically connects — no typing required. WPA2 and WPA3 networks are both supported.

Detailed Guide

A QR Code in 5 Seconds, No Account Required

QR codes appear on restaurant menus, product packaging, event wristbands, business cards, and government documents worldwide — because they're the most reliable way to move someone from a physical surface to a digital destination without typing.

This generator produces static QR codes that encode your content permanently into the image. Enter your URL, Wi-Fi credentials, or text, customize the look, and download as a print-ready SVG or web-ready PNG. The code you create today will still scan in 10 years — as long as your destination URL is still live.

How QR Codes Actually Work

A QR (Quick Response) code is a 2D matrix barcode that encodes data as a grid of black and white square modules. Unlike barcodes, which store data horizontally, QR codes store data both horizontally and vertically — up to 7,089 numeric or 4,296 alphanumeric characters.

The encoding process:

Your input text is converted to a binary bit-stream using one of QR's encoding modes: Numeric, Alphanumeric, Byte, or Kanji
Reed-Solomon error correction codes are generated and interleaved with the data — this is why QR codes scan even when partially damaged or covered by a logo
The binary data fills the QR matrix, starting from the three Finder Patterns (the large squares in three corners that camera apps use for orientation detection)
A mask pattern is applied to distribute dark and light modules evenly and avoid long uniform runs that could confuse scanners

Error Correction Levels:

Level	Recovery Capacity	Best For
L (Low)	~7%	Clean digital displays
M (Medium)	~15%	General printing
Q (Quartile)	~25%	Outdoor signage, dirty surfaces
H (High)	~30%	Logo overlays, damaged labels

Higher error correction = more redundant data = denser (more squares) QR pattern. Level H allows covering up to 30% of the code with a logo and still having it scan reliably.

SVG vs. PNG:

SVG: Vector format, scales to any size without pixelation. Print on banners, posters, billboards at any DPI. Always choose SVG for print.
PNG: Raster pixel format. Perfect for web, email, and digital sharing where exact dimensions matter.

Real-World Use Cases

Restaurants and cafés: Encode your online menu URL. Guests scan the table QR code and see the latest menu — no reprinting laminated cards when prices change.

Event organizers: Link QR codes on tickets...
