Генератор QR-кода

A QR code is a two-dimensional barcode that stores text, a link, contact details or a short note as a grid of black and white squares that any phone camera can read. The more data you encode, the denser the grid becomes.

This generator turns whatever you type into a scannable code, and lets you control the error correction level, the foreground and background colors and the size of the quiet zone, the empty margin that scanners need around the code.

Error correction adds redundancy so a code still scans when it is partly dirty, damaged or covered by a logo. The levels are L, M, Q and H, recovering roughly 7, 15, 25 and 30 percent of the code respectively. Higher levels are more robust but make the code denser, and M is a good default.

Download the result as an SVG for print and anything that must scale without blurring, or a PNG for websites, documents and email. SVG stays razor-sharp at any size because it is vector based.

If a code will not scan, the usual culprits are low contrast, a missing quiet zone, or too much data at a high error correction level. Keep it dark on light, leave the margin, and shorten long text where you can.

These are static QR codes: the data is encoded directly into the image, so a printed code cannot be repointed later. If you need to change the destination after printing, encode a short redirect URL that you control and update where it points. Everything is generated in your browser, so nothing you type is uploaded.
