FAQs
How does this QR code generator work?
It converts your text (URL, WiFi string, contact card, or any message) into a QR matrix in your browser, then renders a preview and lets you download a PNG.
Is it safe and private to use?
Yes. QR generation happens locally in your browser, so your content does not need to be uploaded to a server to create the QR image.
Which error correction level should I pick (L/M/Q/H)?
Use M for most cases. Choose Q or H for better scan reliability (logos/printing), and L for maximum capacity when space is tight.
What size should I use for printing?
For print, a larger PNG (often 400–600px or higher) improves scan reliability. Also keep strong contrast between foreground and background colors.
Why won’t my QR code scan?
Common issues include low contrast, too small size, not enough margin (“quiet zone”), or overly dense content. Increase size/margin or use Q/H correction.
