QR Code Generator
About this tool
Creates QR codes for URLs, text and Wi-Fi. Module placement uses the qrcode-generator library, and text is encoded as UTF-8 so non-Latin text scans correctly. https://scottools.com becomes a 25 × 25 module code.
Wi-Fi mode builds WIFI:T:WPA;S:name;P:password;; so phones join without typing the password. Error correction L/M/Q/H recovers up to 7/15/25/30% damage; higher levels make denser codes.
Codes are drawn black on white so they scan even in dark mode. Download PNG (256/512/1024 px) or SVG, which scales without blurring. Nothing goes through a server, so the code never expires.
FAQ
Do the QR codes expire?
No. The content is in the code itself, with no redirect server.
Which error correction level?
M for most uses; Q or H if a logo covers part of it or it may get damaged.
PNG or SVG for print?
SVG scales without blurring, which is best for print.
