How QR Mint works
QR Mint builds every code with a compact QR Code encoder that runs entirely inside your browser — the same Reed–Solomon error correction and masking logic used by professional QR libraries, just with no server round-trip. Type a link, Wi‑Fi network, contact, or note; the preview updates live; hit Mint PNG or Mint SVG to download. Nothing you enter is ever sent anywhere — close the tab and it's gone.
Choosing an error-correction level
QR codes carry their own repair data, so they can still scan even if part of the code is scuffed, glared, or partly covered by a logo. Higher levels (Q, H) survive more damage but need a denser, larger code for the same content — L or M is plenty for a clean screen or sticker; go higher for anything printed small, laminated, or likely to get scratched.

How QR codes actually work
Modules, finder patterns, and Reed–Solomon error correction — the anatomy of a QR code, explained from the pixel up.
Error correction levels explained: L, M, Q, H
What each level actually tolerates, how much bigger the code gets, and how to pick the right one for print vs. screen.
How to share Wi‑Fi with a QR code
The WIFI: payload format, what phones do when they scan it, and the security tradeoffs worth knowing before you print one.
QR code design tips that still scan
Colors, contrast, logos, and quiet zones — how far you can push the look of a code before a scanner gives up on it.
FAQ
Is this really free, with no sign-up?
Yes. QR Mint doesn't have accounts, limits, or watermarks — mint as many codes as you like.
Do my QR codes expire?
No. Every code QR Mint generates encodes your actual content directly (a "static" QR code) — there's no redirect service in the middle that could go offline or expire.
PNG or SVG — which should I use?
SVG is a vector file that stays crisp at any size — best for print, posters, and anything you might resize later. PNG is a fixed-size image — simplest for slides, docs, and the web.
Does anything I type get uploaded?
No. Every code is built and rendered locally, in your browser's own memory. QR Mint has no backend that ever sees your links, Wi‑Fi password, or contact details.
