About QR Code Generator — Free Online Tool

QR Code Generator encodes a URL, a Wi-Fi network, a contact card or plain text as a QR code, and downloads it as PNG or SVG. SVG is the one to take if the code is going on anything printed, because it stays sharp at any size.

The text you enter is encoded directly into the symbol, so the code works offline and forever: there is no short link in the middle that could expire, no redirect service, and no tracking of who scanned it. A Wi-Fi code carries the network name and password in the standard format phones already understand, so a guest joins by pointing a camera at it.

The code is drawn in your browser. The URL, password or contact details you type are never sent anywhere, which matters most for the Wi-Fi option — that payload contains your network password in plain text.

A Wi-Fi code for guests to scan instead of typing a password, a menu or price list link for a table card, contact details on a business card, and a link to a form or review page on printed material.

When to use it

A printed QR code is the shortest path from a physical surface to a digital action: a menu, a payment page, a Wi-Fi login a guest does not have to type by hand. These codes are static, so the data lives in the image itself — there is no redirect service in the middle that can expire, start charging, or log your scans.

How it works

Your input is assembled into the payload string the relevant specification defines (a WIFI: string, a vCard 3.0 block, a mailto: URI), then encoded at the error-correction level you choose and rendered as both a PNG bitmap and an SVG.

Choosing an error correction level

L recovers about 7% damage, M 15%, Q 25%, H 30%. Higher correction spends more modules on redundancy, so the pattern gets denser and has to be printed larger. M suits screens and clean print; choose H if a logo will sit over the middle or the code will be handled and scuffed.

The quiet zone is not decoration

The specification requires four modules of blank margin on all four sides. Crop it to make the code fit a layout and many scanners stop recognising the code at all. If space is tight, shrink the code rather than trimming its border.

Why the SVG matters for print

A QR code is geometry, not a photograph. The SVG stays mathematically exact at any size, so a code blown up for a poster keeps crisp module edges. An enlarged PNG gets soft edges, and soft edges are what make a scanner hesitate.

Step-by-Step Tutorial

How to Use QR Code Generator in 4 Easy Steps

Follow this simple guide to process your files in seconds directly inside your browser tab.

01

Provide Input for QR Code Generator

Paste your payload, code snippet, or string into the QR Code Generator editor workspace. A QR code is a two-dimensional barcode defined by ISO/IEC 18004. It holds up to 2,953 bytes in a grid of light and dark modules, with Reed-Solomon error correction so it still reads when part of it is dirty or covered.

02

Configure Formatting & Validation Rules

Select indentation preferences, minification, encoding options, or validation rules. A printed QR code is the shortest path from a physical surface to a digital action: a menu, a payment page, a Wi-Fi login a guest does not have to type by hand. These codes are static, so the data lives in the image itself — there is no redirect service in the middle that can expire, start charging, or log your scans.

03

Run In-Browser Engine

The engine executes QR Code Generator locally in your browser with microsecond latency and zero server transmission.

04

Copy or Download Output

Copy the sanitized, formatted, or generated output directly to your clipboard or download it for your project.
