Free QR code generator — create QR codes online

Looking for a QR code generator that stays private? This free QR code generator is a full QR code maker for links, WiFi, contacts, and more. Whether you search for qrcode generator or QR code generator, you can create QR code files in your browser and download PNG or SVG with no account and no watermark.

QR code generator with logo

Need a QR code generator with logo? Upload your brand mark, tune logo size and margin, and pick a higher error-correction level so scanners still read the code. Style modules with custom foreground and background colors, rounded dots, corner shapes, or a transparent background for overlays.

WiFi, vCard, and more QR types

Use WiFi mode to encode network name, password, and security so guests can join without typing. Also create URL, text, email, phone, SMS, and vCard contact codes from the same QR code maker — a practical way to create QR code assets for print, packaging, and digital campaigns.

PNG and SVG downloads

Export PNG for social posts and slides, or SVG for print and design tools. This free QR code generator keeps generation on your device — your links, WiFi passwords, and logos are not uploaded to ImgTask servers.
