QR Code Generator: how to use it (and choose the right settings)

What this tool does

The QR Code Generator encodes a link or any text into a QR code you can download as a PNG image or an SVG vector. These are static codes: the data is baked into the image itself, so there's no account, no tracking redirect, and nothing that can expire. The whole thing runs in your browser.

How to use it

1. Open the QR Code Generator.
2. Type or paste a link or text — the code updates live as you type.
3. Pick an error-correction level (Medium is a good default).
4. Click Download PNG or Download SVG.

What error correction does

QR codes include redundancy so they still scan when partly dirty, damaged, or covered. Higher levels add more redundancy at the cost of a denser code:

• Low (7%) — most data per size; use for clean digital displays.
• Medium (15%) — the usual default balance.
• Quartile (25%) — more robust for print.
• High (30%) — best when you'll overlay a logo or expect wear.

PNG or SVG?

• PNG — a ready-to-use image for documents, slides, and the web.
• SVG — a vector that scales to any size with perfect sharpness; ideal for posters, packaging, and professional print.

Tips for codes that scan reliably

• Keep the quiet zone (the white border) — don't crop right to the edge.
• Maintain strong contrast; dark code on a light background scans best.
• Print large enough for the scanning distance, and test before you publish.

Your data stays private

The code is generated locally with a small library bundled into the page — nothing you enter is sent anywhere. That means it works offline and is safe for private or internal links.

FAQ

Is my data sent anywhere?

No. Generation is entirely in-browser; your text never leaves the page.

Do these codes expire?

No — they're static, so the downloaded image keeps working indefinitely.

PNG or SVG?

PNG for everyday use; SVG when you need to scale or print large without losing sharpness.
