Why vector formats matter for print
Raster images (JPG, PNG) are made of pixels. When you enlarge a PNG QR code beyond its original resolution, the edges blur and the code becomes unreadable. Vector formats (SVG, PDF, EPS) are made of mathematical curves — they stay perfectly crisp at any size, from a 2cm business card to a 3-metre banner.
Professional printers and designers expect vector files. Sending an SVG or EPS means the printer can place the QR code at exact dimensions without any quality loss, and your designer can adjust colors inside their layout software without requesting a new export.
genqrfree.com is one of the few free QR generators that offers true vector SVG, PDF, and EPS exports — not raster images embedded inside a PDF container. This matters for offset lithography, large-format printing, and packaging artwork where quality standards are strict.
Frequently Asked Questions
What file format should I use for printing QR codes?
Use SVG, PDF, or EPS for professional printing — these are vector formats that scale to any size without pixelation. PNG is acceptable for small prints and digital use at 300 DPI or higher.
What resolution do I need for a print QR code?
For offset or digital print, aim for at least 300 DPI at the intended print size. genqrfree.com lets you download PNG up to 2000×2000px, which is 300 DPI at roughly 16cm × 16cm. For larger prints, use SVG.
What is the minimum print size for a QR code?
The recommended minimum is 2cm × 2cm for short-distance scanning (business cards). For posters scanned from 1m+, use at least 5cm × 5cm. For banners at 2–3m, aim for 10cm × 10cm or larger.
Can I use a white QR code on a dark background?
Yes. Use the color picker to set a dark foreground and light or transparent background, or invert to white foreground on a dark background. Ensure at least 70% contrast between the two colors.
Do I need to add a quiet zone (white border) for printing?
Yes. The QR code standard requires a quiet zone of at least 4 modules wide on all sides. genqrfree.com includes this automatically in all downloads.
Is genqrfree.com free for commercial print use?
Yes. All downloads — including SVG, PDF, and EPS — are free with no watermark, no license fee, and no account required.
