QR Code Generator
Generate QR codes from links or text, pick size and error-correction level, then download a crisp PNG. Rendered locally via a small bundled library — no tracking images, no API.
Choosing error correction
The four levels trade capacity for robustness: L is smallest and decodes fastest, M is the everyday default, Q/H survive scratches or logo overlays (H allows covering up to ~30% of the code). The rendering library loads once from a public CDN (qrcode by soldair) and then runs entirely in your browser — the generated matrix never leaves your device; only the one-time script fetch needs connectivity.
How to use QR Code Generator
Type or paste the target — URL, plain text, Wi-Fi credentials, contact details — and the QR code renders live. Pick an error-correction level: L fits the most data, H survives up to 30 percent damage and leaves room for a logo overlay. Copy the SVG markup or download a PNG right-sized for your use.
Keep the quiet zone (the white border) intact when embedding — scanners fail most often because the code touches other artwork. Dark on light scans far more reliably than inverted colors, and URL payloads benefit from being as short as possible for a cleaner, larger module grid.
Frequently asked questions
What error correction level should I pick?
Level H tolerates 30 percent damage and suits placing logos over the code. Level M balances size and robustness for plain links and is the sensible default.
How much text fits in one QR code?
Up to roughly four thousand alphanumeric characters at high version numbers, but scannability drops quickly — keep the payload short and let redirects expand it.
Are the generated QR codes free to use?
Yes. Codes are drawn as SVG and PNG locally with no watermark, license or tracking service. The pattern encodes exactly your text and nothing else.
Do the codes expire?
No. The code is a plain image of your content. It stops working only if the target content itself disappears, exactly like any other print of the same string.
