Types of QR Codes
All-in-One QR Code
"All-in-one QR code" usually describes a generator offering multiple content types, styling options and download formats in a single tool — the convenience of not needing several separate single-purpose QR tools — rather than a distinct kind of code.
Practically, look for: multiple content-type presets (not just plain URLs), color and dot-style customization, and export to more than one file format (SVG for print, PNG/JPG for digital use) — all from one interface rather than juggling different tools for different needs.
