Design & download
Colours, logos and frames without breaking scannability, plus which file format and size to download for print or screen.
Can I download my QR code as SVG, PDF or another vector format? Video
Yes. Open the code, click Download, and pick SVG in the Save as... dialog. JPEG, PNG and PDF are there too. Paid plans and the free trial get all four.
How do I add a logo to my QR code without breaking it?
Open Add Logo on the QR Design step, pick a preset or upload a file under 2 MB, and set the size. Error correction jumps to H so the code still scans.
How do I change the colours, dot style and corners of a QR code?
Everything lives in the wizard's QR Design step: Themes for a one-click look, QR Code Style for dot pattern and colours, Corners for the three eyes.
How do I add a "Scan me" frame or label to a QR code?
Open Frame on the QR Design step, pick one of 20 frames, then set the colours and type your own text in CTA Text. Frames come through in every download format.
How do I export a print-ready PDF or a CMYK file?
Open Download, pick PDF and a page format from A4 to A0. CMYK is a JPEG-only option — SVG and PDF have no colour-mode switch.
Which size and resolution should I download for print or screen?
512 px for screens, 2048 or 4096 px for print, and SVG for anything a printer will scale. PNG and JPEG offer 512, 1024, 2048 and 4096 px.
Can I download a QR code with a transparent background?
Yes, in PNG and SVG. Tick Transparent background in QR Code Style before you save the code. JPEG always flattens to white, and the PDF page is white.
What do error correction and pattern density do?
Error correction sets how much damage a code survives; density sets how many modules it is drawn with. Both live in Advanced on the QR Design step.
How do I download a QR code again after creating it?
Open My QR Codes, use the row menu's Download, and pick a format in Save as... You can download the same code as often as you like, in any format.
