Which error-correction level should I use?

M (15%) is a reasonable default for most uses; go up to Q or H if the code will be printed small, placed on a curved or textured surface, or partly covered by a logo, since higher levels tolerate more damage.

Can I put a logo in the middle of the QR code?

This tool doesn't overlay a logo image, but choosing a higher error-correction level such as Q or H leaves enough redundancy that a small logo added afterward in an image editor often still scans.

Can this generate a Wi-Fi or contact card QR code?

You can paste a Wi-Fi or vCard payload string in by hand and it will encode correctly, but the Wi-Fi QR code generator and similar dedicated tools build that payload's exact field syntax for you.

Is the text I encode sent to a server to build the QR code?

No, the QR pattern is computed by a JavaScript library running in your browser tab, so the URL, message or any other text you type is never transmitted before the code is drawn.

Turn text or a URL into a QR code you can style

This tool encodes whatever text or URL you type into a QR code, redrawing it live as you change the size, error-correction level, margin or colors. It covers the everyday case of linking a printed flyer or business card to a page, but since it just encodes raw text, it also works for a Wi-Fi payload, a vCard or plain notes. The encoding runs through a JavaScript library in the page itself, so the text going into the code is never sent to a server first.

How to use the QR Code Generator

Type or paste the text or URL you want encoded into the editor.
Pick an output size from 160px up to 800px.
Choose an error-correction level: L, M, Q or H, trading code density for damage tolerance.
Set the margin and pick dark and light colors for the code, if the default black-on-white doesn't fit.
Download the result as a PNG for screens or an SVG for print at any size.

Error correction lets a scanner still read the code if part of it is damaged or obscured, at the cost of a denser pattern for the same data: L recovers about 7% of the code, M about 15%, Q about 25% and H about 30%.

The tool encodes exactly the text you give it, with no built-in field structure, so for a Wi-Fi network's SSID and password specifically, the dedicated Wi-Fi QR tool builds the correctly escaped payload for you.
