QR Code Generator

How to use

Enter the text or URL you want to encode. As you type, the QR code appears instantly. Adjust the size, foreground and background colors, and error-correction level to match your needs, then download the result as a PNG (for screens) or SVG (for print). No sign-up, no watermark, no limits.

How QR codes work

A QR (Quick Response) code is a two-dimensional barcode that stores data in a grid of black and white squares. A scanner reads the pattern and decodes it back into the original text or URL. Unlike a traditional barcode, a QR code holds data both horizontally and vertically, so it can store far more information in a compact space.

The three large squares in the corners are finder patterns — they tell the scanner where the code is and how it's oriented, so it reads correctly from any angle. The rest of the grid encodes your data plus error-correction bits, which let the code be read even when partially damaged.

These are static QR codes: the data is encoded directly in the pattern. That makes them permanent and free to generate, but it also means the destination can't be changed after the code is created. When you need an editable, trackable code, the Dynamic tab creates a short redirect link instead — the printed pattern stays the same while you re-point it whenever you like.

Worked example

Say you run a café and want a QR code linking to your digital menu at https://example-cafe.com/menu. Paste that URL into the field. Set the size to 512px for a crisp table-tent print, keep the foreground black and background white for maximum contrast, and set error correction to High (~30%) so the code still scans if a coffee ring smudges one corner. Download the SVG so it stays sharp when your printer scales it up. Test it with your phone camera before sending it to print — always test before a production run.

Tips and common mistakes

• Always test before printing at scale. Scan the code with a few different phones. A code that looks fine on screen can fail in print if contrast or size is off.
• Keep strong contrast. Dark foreground on a light background scans best. Inverted (light on dark) codes often fail, and low-contrast color pairs are unreliable.
• Don't make it too small. For print, a QR code should be at least 2 × 2 cm (about 0.8 inch). Smaller codes are hard for cameras to focus on, especially from a distance.
• Leave the quiet zone. QR codes need a margin of empty space around them to scan reliably. Don't crop right to the edge or place text/graphics too close.
• Put one on anything you print for money. A payment URL typed by hand off a paper bill is a typo waiting to happen. Generate a code for your payment link, download the PNG, and drop it into the invoice and receipt generator — the client scans instead of transcribing, and you get paid sooner.
• Raise error correction if you add a logo. Covering part of the code with a logo removes data; High error correction compensates so it still scans.
