How to Make a QR Code Without Downloading an App

Search "free QR code generator" and the results are a minefield: sites that generate a code fine, then require an account to actually download it at usable resolution; "free" generators that quietly create a tracking/redirect link instead of encoding your actual URL directly, so the QR code stops working the moment their service goes down or decides to paywall it; apps that want a phone number and permissions for something that's fundamentally just an image.

What a QR code actually is

It's not magic, and it's not something that needs a server round-trip. A QR code is a direct, deterministic encoding of text (usually a URL) into a grid of black and white squares, following a public, open specification. Generating one is pure computation — text in, image out — with no account, no tracking redirect, and nothing that can "expire" or stop working later, because the code encodes your actual content directly, not a link to someone else's shortener.

Why the redirect-link version is the real risk

A QR code that encodes a tracking/shortener URL instead of your real destination directly means the code's usefulness depends entirely on that third-party service staying online and not deciding to paywall or sunset the redirect. Print a thousand flyers with one of those, and if the service disappears, so does the destination — permanently, with no way to fix already-printed codes. A code that encodes your real URL directly has no such dependency.

QR Code Generator generates real, scannable codes instantly in your browser — no account, no redirect link, no dependency on anything staying online later.
