SEO Experiments tool
QR Code Generator.
Build QR codes for URLs, WiFi credentials, contact cards, email links, SMS, phone numbers, geo coordinates, calendar events, and plain text. The preview uses the same domain endpoints as production exports.
Payload builder
Choose a format or edit the final payload directly. For print, use ECC Q or H and keep high contrast.
Server engine supports byte-mode QR versions 1-10. Keep payloads concise for reliable scanning and smaller codes.
Output settings
These controls update the same SVG and JSON endpoints you can use from other pages or scripts.
Fast presets
Load examples without changing your design work.
Batch endpoint builder
Paste one payload per line to create reusable SVG endpoint URLs. This does not upload or store anything.
