How this generator works

Create custom QR codes in your browser: set content, colors, shape and logo, then download PNG or SVG. No account needed.

How to use it

Enter a URL or text in the content field.
Adjust colors, module shape and, optionally, a center logo.
Choose error-correction level and output size.
Download PNG (good for screens and simple print) or SVG (vector, better for scaling).

PNG vs SVG

PNG is a raster image: fine for the web, messaging apps or a fixed print size. SVG is vector: it scales cleanly and suits posters or further editing.

Center logo

A logo covers part of the code. This tool forces high error correction (H) when a logo is present. Prefer a simple logo with strong contrast and keep margin around it.

Privacy

The QR is generated in your browser (canvas). Content and logo are not uploaded to a Caprini server to generate the code. Only the language preference is stored on your device.

Practical tips

Keep strong contrast between modules and background.
Leave margin (quiet zone) around the code.
Scan with your phone before printing many copies.
For large prints, prefer SVG or a high-resolution PNG.

FAQ

Do I need an account? No. The tool is free and works without signup.

Does the QR expire? No. It is a static image. It only changes if you change the encoded URL or text.

Why does it not scan well with a logo? The logo reduces usable area. Shrink the logo, improve contrast, or try without a logo.
