QR code generator

What it does

A QR code generator encodes a link, a block of text, Wi-Fi credentials or a contact card into a scannable image. Everything is generated in the browser, so the data never goes to a server and there is no account or expiry. You can set the size, the error correction level and the colours, see the code update as you type, and download a PNG for screens or an SVG for print. The encoded data is shown as text so you can check exactly what a phone will read.

How to use it

1. Choose what to encode: a website link, plain text, a Wi-Fi network or a contact card.
2. Fill in the fields. For a link, keep it short; shorter data makes a simpler, more forgiving code.
3. Pick the error correction level and, if you need brand colours, a dark foreground on a light background.
4. Download the SVG for print or the PNG for screens, and test it with a phone before it goes to the printer.

How to read the result

The status badge says "Scannable" when the data fits in a QR code at the chosen level. The character count underneath is what matters for density. At level M, a 20-character URL fits in a 25 by 25 module code; a 300-character vCard needs 69 by 69 modules and has to be printed larger or scanned from closer.

The print size figure is a rough minimum at arm's length. A code with 40 characters shows about 2.5 cm; the 160-character sample contact card about 5.5 cm. Scale up for posters, where people scan from further away: as a rule the code should be at least a tenth of the scanning distance.

The encoded data block shows the raw string. For Wi-Fi it reads WIFI:T:WPA;S:Office Wi-Fi;P:secret;; and for a contact it is a VCARD block. If a phone shows something unexpected after scanning, this is where to look.

Add UTM tags to a printed link so scans show up separately in analytics. Print and web assets that match are part of the brand work in our website design and development service.
