What the code is for
Type the address on the left. Whatever is in that box is exactly what a phone opens — no
shortener, no redirect.
How much damage it can take
A tougher code survives a scuff, a fold or a logo. It costs dots, so it has to be printed
bigger.
The file
How many pixels across
PNG opens anywhere. SVG stays sharp at any size, from a business card to
a banner.
Privacy
Made in this tab. No link is wrapped, shortened or counted, so nobody can switch off a
code you have printed.
A QR code is not private. Anyone who scans it reads everything in it.
