# QR Code Generator

Updated: 2026-10-03

The QR Code Generator encodes your URL or text directly into a QR code image. Choose 256 to 1024 pixels, one of four error correction levels (L/M/Q/H) and foreground and background colors, then download a PNG. The QR code contains exactly what you typed — no short links or redirect services — so it never expires and cannot be tracked.

## How to use the QR Code Generator

1. Enter a URL or text in "Content".
2. Choose the size and error correction level; use 1024 for posters.
3. Adjust the colors if needed — keep strong contrast (dark on light scans best).
4. The preview updates live; press "Download" for the PNG.

## FAQ

### Will the QR code expire?

No. This tool creates static QR codes: the URL is stored in the pattern itself and never passes through our server, so it works as long as your URL does.

### Can I use it commercially?

Yes. You can use the generated QR codes on business cards, posters, packaging and other commercial materials.

### Why won't my QR code scan?

Usually the contrast is too low, the image is too small or the print is blurry. Use a dark foreground on a light background, print at least 2 × 2 cm and keep a quiet margin around it.

### Can I add a logo?

The tool does not add logos. If you add one yourself, choose error correction H and keep the logo under 20% of the area.
