The QR image is rendered on our server from the data you enter, then sent back to your browser — it is not stored, logged, or used for anything else.
About QR codes
A QR (Quick Response) code stores data as a grid of black and white squares that a camera can read in a fraction of a second. Unlike a barcode, which only reads in one direction, a QR code packs data in two dimensions and adds redundant information so it can still be read when part of it is dirty, torn, or poorly lit — that redundancy is the error-correction level you choose above.
The code you build here is static: everything you type is encoded directly into the pattern itself, with nothing stored on a server and nothing that can expire or be redirected later. That also means it can't be edited after the fact — if the underlying URL or Wi-Fi password changes, you'll need a new code.
Why some QR codes fail to scan
The most common causes are a missing quiet zone (the plain border around the pattern), foreground and background colors without enough contrast, and printing the code too small for its density. A denser code — more data, or a higher error-correction level — needs more physical size to stay reliably scannable.
Frequently asked questions
What is error correction, and which level should I pick?
A QR code carries redundant data so it can still be read even if part of it is dirty, torn or poorly lit. Level L recovers from about 7% damage, M about 15%, Q about 25%, and H about 30% — but higher levels also pack the same data into a denser, larger-looking symbol. M is a reasonable default for a screen; use Q or H for anything that will be printed small or handled a lot.
Why does the QR code change size depending on what I type?
A QR symbol comes in 40 fixed sizes ("versions"), and the generator always picks the smallest one that fits your text at the error-correction level you chose. Longer text, or a higher error-correction level, both push it toward a bigger, more detailed symbol.
Why won't my QR code scan?
The most common causes are: too little white space around the edge (the "quiet zone" — keep the margin at 4 modules or more), foreground and background colors that are too close in contrast, or a logo/margin so small the code was cropped. If in doubt, scan it yourself before you print or publish it.
PNG or SVG — which should I download?
PNG for screens, slides, and anywhere a fixed-size image is fine. SVG for print or any design tool, because it stays crisp at any size — a poster-sized QR code from a PNG can turn blurry, an SVG never does.
Does a Wi-Fi QR code expose my password?
Anyone who scans it can join the network, the same as if you'd told them the password out loud. It's meant for handing to a guest, not for posting somewhere public.
Is this the same as a "dynamic" QR code from a tracking service?
No. This produces a static code — the data you entered is encoded directly into the pattern, permanently. A dynamic QR code instead points to a short redirect URL that a service can repoint later and use to log scans. Static codes never expire and never phone home; they just can't be edited after the fact.
