QR Code Generator

Virtually anything that can be expressed as text: a website URL, an email address, a phone number, plain text, WiFi credentials, a vCard contact, or a short message. Most QR scanner apps detect the content type automatically and take the appropriate action (open a browser, compose an email, connect to WiFi, etc.).

Static QR codes — the kind this tool generates — never expire. The data is encoded directly in the pattern itself. The only way a static code "breaks" is if the URL it points to goes offline or changes. Dynamic QR codes (which route through a redirect server) can expire, but those are a different product.

Yes. Pick any foreground and background color using the color pickers. The only requirement for reliable scanning is sufficient contrast — a dark foreground on a light background works best. Avoid light-on-light or dark-on-dark combinations.

For business cards and small stickers, 200-300px is usually enough. For posters and signage meant to be scanned from a distance, go 300-500px. The general rule: the farther the scanner, the larger the code needs to be. Always test a print at actual size before a full run.

QR codes store data as bytes, so UTF-8 encoded text (including emoji and non-Latin scripts) works. However, the more data you encode the denser the pattern becomes, which can reduce scannability on low-end cameras. Keep Unicode payloads short for best results.

The most common causes are insufficient color contrast (e.g., light gray on white), printing too small for the scanning distance, or placing the code on a curved or reflective surface. Try increasing the size, switching to black-on-white, and printing on a flat matte material.

This tool generates standard QR codes without logo overlays. The error correction level (M) can recover about 15% of damaged data, so a small centered logo may still scan — but it is not guaranteed. Dedicated QR-with-logo services handle this more reliably.

A static code encodes the final URL or text directly — it is permanent and free. A dynamic code encodes a short redirect URL that a third-party service controls, allowing you to change the destination later and track scan analytics. This tool generates static codes.
