Your input never leaves the browser. The QR pattern is computed in JavaScript and rendered to an SVG/canvas before download.

No watermark. No login. The downloaded QR is yours to use commercially.

Frequently asked questions edit

A QR (Quick Response) code is a two-dimensional barcode that any modern phone camera can read. The pattern of black and white squares encodes text — usually a URL — which the scanning app then opens, dials, or displays.
SVG for anything printed (posters, business cards, packaging) because it stays sharp at any size. PNG for screens, emails, social media, and apps that don't accept SVG. Both are produced by this tool.
QR codes contain redundant data so the code still scans even if part of it is damaged. L recovers up to 7%, M up to 15%, Q up to 25%, H up to 30%. Use H if you want to place a logo over the centre; use M for everyday use.
Scanners need strong contrast between dark and light modules. Keep the foreground dark and the background light; do not invert them (most cameras refuse to read a light-on-dark QR). Avoid colours that are too close in luminance.
Yes. Pick Wi-Fi, enter your SSID and password, choose the encryption type, and generate. iOS, Android and most camera apps connect automatically when the code is scanned. The credentials are encoded inside the QR — anyone with the image can read them.
No. The QR pattern is calculated entirely in your browser by a small JavaScript library. Your URL, contact, Wi-Fi password, or any other input never leaves your device. The download is generated locally too.
A general rule of thumb: at least 2 cm (0.8 in) across for handheld scanning, and 10× the scanning distance in cm for billboards. Smaller is fine if scanners get close, but always test with a real phone before mass-printing.
This tool produces clean SVG and PNG without a built-in logo overlay. To add a logo, generate at high error-correction level (H), open the SVG in a vector editor (Figma, Illustrator, Inkscape), and place your logo in the centre covering no more than 25% of the area.
