Free QR Code Generator: Encode URLs, Text & Wi-Fi into Scannable Codes
A QR code generator turns a URL, plain text, Wi-Fi login, or contact card into a square, scannable matrix barcode. Type your content, pick foreground and background colors and an error-correction level (L, M, Q, or H), then download a crisp SVG or a PNG. The codes are static — they never expire and need no subscription — and everything runs 100% in your browser, free, with no upload.
How to generate a QR code
- Type or paste your content into the box: a full URL, plain text, a Wi-Fi string, or a vCard.
- Set the Foreground and Background colors with the pickers or by pasting a HEX value — keep the foreground dark and the background light.
- Choose an Error Correction Level; M (15%) is the default and suits most printing and screen use.
- Drag the Size slider from 128px to 1024px and leave Include Standard Margin on to keep the quiet zone.
- Click Download SVG for print or Download PNG for quick web use — the preview updates live as you change any setting.
What is a QR code and how does it work?
A QR (Quick Response) code is a two-dimensional matrix barcode invented by Denso Wave in 1994 and standardized as ISO/IEC 18004 (current edition 2024). Unlike a 1-D barcode that stores data in one direction, a QR code packs data both horizontally and vertically into a grid of black and white modules. The three large squares in the corners are finder patterns that tell a scanner the code's orientation; smaller alignment patterns keep it readable on curved surfaces.
Symbols come in 40 versions, from 21×21 modules (version 1) to 177×177 modules (version 40), growing by four modules per side. Each version supports four Reed-Solomon error-correction levels — L, M, Q, and H — which let a scanner rebuild data even when part of the code is scratched, smudged, or covered by a logo.
"The four levels of error correction (L, M, Q, H) allow recovery of 7%, 15%, 25%, and 30% of the symbol codewords, respectively."— ISO/IEC 18004, QR Code bar code symbology specification
This tool renders codes with the qrcode.react library, which automatically picks the smallest version that fits your content at the level you choose. The optional quiet zone (the blank margin around the code) is on by default — without it many cameras cannot tell where the code begins.

Edge case · PNG looks blurry when printed large
The on-screen preview canvas is capped at about 200px for layout, and the PNG download is captured from that canvas — so a PNG can look soft when scaled up for print. The SVG download exports at the full size you set (up to 1024px) and is resolution-independent. For business cards, packaging, or billboards, always choose Download SVG.
QR error-correction levels and capacity reference
Recovery rates are fixed by ISO/IEC 18004. Capacities below are the maximums at the largest symbol (version 40) for that level — higher correction means fewer data characters fit, because more of the code is spent on redundancy.
| Level | Recovers | Max numeric (v40) | Best for |
|---|---|---|---|
| L (Low) | 7% | 7,089 | Clean digital screens; least dense code |
| M (Medium) | 15% | 5,596 | Default — business cards, flyers, menus |
| Q (Quartile) | 25% | 3,993 | Small center logo overlay |
| H (High) | 30% | 3,057 | Outdoor, rugged surfaces, large logos |
For reference, version 40-L also holds up to 4,296 alphanumeric characters or 2,953 bytes of UTF-8 text.
The download gotcha most QR tools never mention
On this tool the PNG and SVG are not the same resolution. The visible preview is a <canvas> capped at Math.min(size, 200) pixels, and the PNG is read straight off that canvas with canvas.toDataURL() — so even if you set the size slider to 1024px, the PNG file is roughly 200px wide. The SVG, generated separately with qrcode.react's vector renderer, uses your full chosen size and scales cleanly to any dimension.
Practical rule: use PNG only for small on-screen or chat use, and SVG for anything printed or resized. Static codes also have a real privacy edge over "dynamic" paid codes — a dynamic code routes every scan through a vendor redirect that can log the scanner, change the destination later, or break if the subscription lapses.
Runs 100% in your browser
Your content never leaves your device. The QR code is drawn locally in JavaScript and both downloads are built in the browser — no uploads, nothing leaves your device. I tested this generator with URLs, multi-line vCards, and Wi-Fi strings across all four error-correction levels, at sizes from 128px to the 1024px maximum, in both PNG and SVG. The SVG export held up sharp when scaled for print, while the PNG stayed at the on-screen preview resolution — reach for SVG whenever quality matters.
Frequently asked questions
Is this QR code generator free?
Yes — 100% free with no signup, no scan limits, and no watermarks. The codes are static, so you can use them on business cards, packaging, menus, and websites for personal or commercial work without any fee.
Does it run in my browser or upload my data?
It runs entirely in your browser with the qrcode.react library. Your content is never sent to a server, and both the PNG and SVG download happen on your device, so the tool works offline once the page loads.
Do these QR codes expire?
No. These are static codes with the data encoded directly into the pattern — there is no redirect server and no subscription, so the code keeps working as long as the destination stays valid.
Should I download PNG or SVG?
Choose SVG for printing — it is a vector and stays sharp at any size. On this tool SVG exports at your full chosen size up to 1024px, while the PNG is captured from the ~200px on-screen canvas, so use SVG whenever quality matters.
