FAQ: Generate a QR code for print
How do I generate a QR code?
Enter a full URL above. Your QR appears instantly below. Click Download SVG for vector artwork or Download PNG for a high‑resolution raster.
What format should I use for print—SVG or PNG?
Use SVG wherever possible for true‑vector output and infinite scaling. If a workflow requires raster, download PNG at high pixel dimensions and ensure the printed module size remains large enough to scan.
What size should a print QR code be?
As a rule of thumb, keep the printed QR at least 20–25 mm on a side for typical viewing distances. Increase size for longer distances or dense content.
Which error correction level should I choose?
For most print uses, M or Q is a good balance of robustness and density. Higher correction improves damage tolerance but increases complexity.
Can I print in black & white only?
Yes. High contrast black foreground on white background is ideal. Avoid reversing (white code on dark) unless you thoroughly test.
What is the quiet zone and why does it matter?
The quiet zone is a blank margin around the QR code that helps scanners detect edges. Keep at least 4 modules of white space.
Will this work for very small QR codes?
Very small QRs can become unscannable due to print and camera limits. Prefer SVG and increase physical size to maintain scan reliability.
Should I design in CMYK or RGB?
For print, work in CMYK and proof on your target stock. Ensure adequate contrast after conversion; pure black on white remains safest.
Can I place a logo inside the QR code?
You can place a small logo in the center if you increase error correction (Q/H) and overall size. Never overlap finder patterns or the quiet zone.
How do I export for my print vendor?
Provide SVG embedded directly in your layout app or export to PDF/X with vectors preserved. If rasterized, use high‑DPI PNG and avoid resampling.
Does URL length affect scan reliability?
Longer content increases symbol density, which can reduce reliability at small sizes. If needed, use a trustworthy branded short link and test thoroughly.
What DPI should I use for PNG exports?
Export at large pixel sizes (e.g., 4096 px) and scale down in layout with image smoothing off. The effective printed size matters more than nominal DPI.
