Frequently asked questions
These answers focus on professional print quality. For quick generation, use the homepage.
How do I generate a QR code?
Go to the homepage, enter a full URL, and download SVG or PNG.
What size should I print?
At least 20–25 mm on a side for typical uses; increase when scanning at distance or using dense data.
Should I use SVG or PNG?
Use SVG for vector workflows. Use PNG only when raster is required, exported at high pixel dimensions.
What error correction level should I pick?
M or Q works well for print. H adds robustness but increases density.
What is the quiet zone?
A rim of white space around the QR; keep at least 4 modules to improve scan reliability.
Should I design in CMYK or RGB?
Design for print in CMYK and proof on your target stock. Ensure strong contrast post‑conversion.
Can I place a logo inside the code?
You can, if you increase error correction (Q/H) and overall size. Avoid finder patterns and the quiet zone.
How do I package files for the print vendor?
Embed SVG directly or export to PDF/X with vectors intact. If rasterized, supply high‑DPI PNG without resampling.
Do long URLs reduce scan reliability?
Longer content increases density. Use a reputable short link when space is tight, and test at actual size.
What PNG size should I export?
Export at large pixel counts (e.g., 4096 px) and scale in your layout with image smoothing off.
