QR Code Generator

Generate a QR code from any text or URL instantly, entirely in your browser.

FreeBrowser-basedInstant

Higher levels tolerate more damage or dirt on the printed code, but produce a denser, more detailed pattern.

Your files are processed locally in your browser and are not uploaded to our servers. The QR code is generated entirely in your browser using JavaScript — nothing you type is ever sent to a server or stored anywhere.

How to use QR Code Generator

Type or paste any text or URL, pick an error-correction level, and a QR code renders instantly below. Download it as a crisp PNG for digital use or as a scalable SVG for print. Everything is generated entirely client-side in your browser using a hand-written encoder — no server round-trip ever happens, so what you encode is never sent anywhere or seen by anyone but you.

Key features

  • Live preview that regenerates as you type or change settings
  • Four selectable error-correction levels (L, M, Q, H) with plain-language explanations
  • Download as PNG for digital use or SVG for crisp scaling and print
  • Automatic quiet-zone margin included in every download for reliable scanning
  • Shows the resulting QR version and module dimensions for transparency
  • Works entirely offline after the page loads, with no server round-trip

Practical use cases

  • Sharing a WiFi password or contact card by having someone scan a code instead of typing it
  • Linking a printed flyer or business card to a website or portfolio
  • Adding a QR code to product packaging that links to more information
  • Generating a QR code for a restaurant menu or event page

Limitations

  • Very long text at a high error-correction level may not fit and will show a clear error rather than a broken code
  • Only encodes plain text/byte-mode data — no specially optimized numeric mode or structured vCard/WiFi formats beyond what plain text naturally supports

Frequently asked questions

What's the difference between the error-correction levels?
Error correction lets a QR code still scan correctly even if part of it is damaged, dirty, or obscured. L recovers from roughly 7% damage, M roughly 15%, Q roughly 25%, and H roughly 30%. Higher levels are more resilient but pack more data into the same space, producing a denser-looking code.
Can I put a URL in a QR code?
Yes. A URL is just plain text as far as the encoder is concerned, so pasting a full https:// link works exactly the same as any other text — most phone cameras will recognize the result and offer to open it as a link.
Why is there white space around the QR code?
That border, called the quiet zone, is a required part of the QR standard, not decoration. Scanners use the clear space around the pattern to detect where the code starts and ends, and a code cropped too tightly can fail to scan reliably — this tool always includes it in both the PNG and SVG downloads.
Does this track what I generate?
No. The entire QR code is built locally in your browser with no server involved, so there is nothing to transmit and nothing for anyone, including this site, to log or see.
