QR code generator
Make a QR code for a link or text
Runs in your browser. Nothing is uploaded.
How it works
A QR code stores text or a link as a grid of squares that a phone camera can read. Enter your link, choose your colours, and download it as a PNG for the web or an SVG for print. It’s made in your browser. Always scan it with a real phone before printing lots of copies.
Your text is turned into a grid of dark and light squares, with spare data so it still scans if slightly damaged.
We use medium error correction, so a code can still scan when slightly damaged. Longer text makes a denser code, which is harder to scan when small.
We warn you if your colours are too close, or if the code is light on dark.
Worked example. Enter a link, then download the code as an SVG for print or a PNG for the web. Scan it with your phone before printing lots of copies.

What this tool doesn’t cover
- A code holds about 2,900 bytes at most, and short text scans best.
- These codes are fixed. You can’t change the link after printing.
Questions
Do these QR codes expire?
No. The link is stored in the code itself, so it works for as long as the link does.
Should I use PNG or SVG?
Use SVG for print, as it stays sharp at any size. Use PNG for the web.
Why won’t my code scan?
The usual causes are low contrast, too small a size, or too much text.
How do I make a QR code for a link?
Paste the link and download the image. The code is made in your browser, and it holds the link itself.
What size should a printed QR code be?
At least 2 cm wide for reading up close. Make it larger for posters, at about a tenth of the scanning distance.
