Quick tips

Pick the right settings the first time

  1. Error correction

    Level L recovers up to 7% of damage, M ≈ 15%, Q ≈ 25%, H ≈ 30%. Use H if you’ll print on stickers or merchandise.
  2. Size

    512×512px is enough for most screens. For print at A5+, use 1024×1024px or the SVG download.
  3. Contrast

    Keep at least 50% contrast between foreground and background, or scanners will struggle in low light.
  4. Test it

    Always scan with two different phone cameras before going live.

FAQ

Frequently asked

What is the smallest QR code I can print?
For reliable scanning, print at minimum 2 × 2 cm (about 0.8 in). Add 10× the QR width as the scan distance — a 2 cm code scans from about 20 cm. Use error correction level H if it will be printed on textured material or behind glass.
Which error correction level should I pick?
L recovers up to 7 % damage and is fine for clean screen displays. M (15 %) is a good default. Q (25 %) is right for stickers and merchandise. H (30 %) is the right call any time the QR may be partially obscured, scratched, or printed on fabric.
Can I add a logo to the middle of the QR code?
Yes — keep the logo under 25 % of the QR width and stick to level Q or H error correction. The QR specification reserves enough redundancy that a small centered overlay does not break scanning.
Do dark mode QR codes work?
They work as long as the contrast ratio is at least 4:1 between foreground and background, and the foreground is the darker of the two. Inverted (light QR on dark) is allowed by the spec but some older scanners struggle — test with two phones before going live.
PNG or SVG — which should I download?
Use SVG for anything that will be printed: it scales to any size without artifacts. Use PNG for digital use where you want a fixed pixel size, or when uploading to platforms that reject vector formats.
Do QR codes expire?
Static QR codes (which this generator produces) never expire — they encode the URL directly. Dynamic QR codes (offered by paid services) route through a tracking server and can be edited later, but they expire if you stop paying.
