QR Code Generator

How to use it

1. 1Enter the text or URL the code should carry.
2. 2Choose the error-correction level and the output size.
3. 3Check the self-scan result, then download PNG or SVG.

Limits worth knowing

• A QR payload is capped by the standard (about 4,296 alphanumeric characters); this tool refuses payloads the encoder cannot fit instead of producing a corrupt code.
• Very long payloads make very dense codes — scan distance suffers.
• PNG output is rasterised at the chosen size; SVG output scales losslessly.
• There is no tracking pixel and no redirect — the payload is exactly the text you typed.

Error correction is not decoration

Reed–Solomon error correction lets a QR code survive damage and partial obstruction. That is why codes printed on lime label stickers still scan: enough modules survive unread for the maths to reconstruct the rest. For a sticker destined to peel, print Q or H; for a logo-embedded QR, print H and keep the logo modest.

The self-scan check in this tool reads the rendered PNG back — if the payload is too long for the chosen level, the error-correction level auto-selection will refuse rather than lie to you.

PNG or SVG

SVG is the right answer for print and for anywhere the code may be scaled: one path, infinitely sharp. PNG at 512 px is fine for screens. Do not upscale a small PNG; render a larger one instead.
