QRMaker Pro is a self-hosted QR code platform built with PHP and vanilla JavaScript. Smart content builders, brand-matched designs, frame captions, and a personal library — all running on a single PHP file with zero database setup.
8 templates, colour presets, hex pickers, frame captions, and gradient backgrounds.
Structured forms for WiFi, vCard, Events, Email, SMS, Geo and Crypto wallets.
PNG / SVG / JPG with adjustable size and background style (white, match, transparent).
From 100px to 2000px. Preview scales proportionally and stays perfectly sharp.
Download PNG, vector-wrapped SVG, printable PDF, or push to your browser's clipboard.
Search, filter by content type, edit labels, duplicate, copy and share saved codes.
Debounced 300ms preview. Canvas-based rendering keeps preview & export pixel-identical.
Polished dual themes that follow your system preference or your manual choice.
The architecture prioritises portability. The backend is plain PHP — no Composer dependencies, no autoloaders. The frontend uses vanilla JS with hash-based SPA routing, so there's no build step.
