QR Code Generator

Type a URL or any text, get a scannable QR code back, download it as a PNG. No account, no tracking pixel embedded in the code, no "scan to see an ad first" redirect layer that some free QR generators quietly insert — what you type is what gets encoded, directly, and rendered in your browser.

What's actually worth knowing about error correction levels

QR codes bake in redundancy so they still scan even when part of the code is damaged, dirty, or partially obscured — that's what the L/M/Q/H levels control. L recovers from roughly 7% damage, H recovers from roughly 30%. Higher correction makes the code visually denser (more small squares) for the same data, which is exactly why H is the level to reach for if you're planning to put a logo in the middle of the code — the logo is deliberately obscuring part of the pattern, and higher error correction is what keeps the code scannable despite that.

Why some QR codes fail to scan and others don't

The most common real-world cause isn't the code itself — it's contrast and quiet zone. QR scanners need a clear margin of blank space around the pattern (the "quiet zone") to find its edges; cropping a QR code too tightly, or placing it directly against a busy background with no margin, breaks detection more often than actual data corruption does. Low contrast — a light grey code on white, or a code printed too small for the scanning distance — is the other common failure mode, and neither has anything to do with the encoded content being wrong.

A URL, not a search query

The most common actual mistake: encoding a URL without the https:// scheme. Some scanning apps handle a bare domain fine and try to guess; others don't, and the phone opens a web search for the literal text instead of navigating to the site. Always encode the full URL including the scheme, and test-scan it with an actual phone before printing it anywhere permanent — a QR code on a poster or a product label is expensive to fix once it's already printed.
