qr-code-generator
Type or paste any text or URL to generate a QR code instantly. Adjust error correction, size, and colors, then download as PNG or SVG.
Pixels per module (the code's individual black/white squares) — higher means a larger, crisper image. Turn this up before printing or scaling the code up significantly.
Most scanners need strong contrast to read reliably — keep foreground and background far apart in brightness. Plain black on white is the safest choice.

// PNG vs. SVG export
PNG is a fixed-resolution raster image — simplest to drop into a doc or slide, but it'll look blurry if scaled up significantly. SVG is a vector format that stays crisp at any size, which matters if the code is going on a poster, a banner, or anywhere it'll be printed larger than a business card.
Error correction lets a QR code still scan correctly even if part of it is damaged, dirty, or obscured — the tradeoff is that higher levels pack less usable data into the same size, producing a denser code.
