How does it work?

The text is encoded into QR symbols using the qrcode library running locally in your browser — the payload never leaves the page. The output is a 1024px PNG.

Higher error-correction levels (Q, H) add redundancy so the code survives logos or damage, at the cost of a denser pattern.

What are the edge cases and limits?

  • Input is limited to 1,000 characters; longer payloads make dense codes that phones struggle to scan.
  • Non-ASCII text is encoded as UTF-8; most modern scanners handle it, but very old ones may not.
  • PNG output matches the live IT Tools download contract; the previous local SVG output is no longer the primary result.
