QR codes
Sizes, error correction, colours and logo.
Download
The QR code always encodes the short link, so there is no need to reprint after the destination changes. PNG and SVG are available at 256, 512 and 1024 px.
Colours and contrast
On paid plans you can choose colours, the shape of dots and corner markers, a gradient and a frame with a short caption. Too low contrast is refused — such codes scan badly.
Logo
Upload a PNG or SVG logo in “Settings → Logo for QR codes” and tick “Logo in the centre”. The logo takes at most 22% of the code, and error correction automatically becomes H.
