What is QR Code Generator?

Generate downloadable SVG QR codes for URLs, text, Wi-Fi notes, or contact snippets.

Generate SVG QR codes
Download scalable output
Create codes for URLs or plain text

How to use it

Enter the exact URL or text to encode.
Generate the QR code and inspect the SVG output.
Download the SVG and place it with clear contrast and sufficient quiet space.
Scan the final rendered asset on multiple target devices before publishing or printing.

Quick example

Example input

https://datahub.ac.cn/tools/

Expected output

An SVG QR code using medium error correction

A valid QR image can still lead to the wrong or unsafe destination. Verify the encoded text before distribution.

Best use cases

Create SVG QR codes for URLs and short text.
Prepare scalable codes for documentation and print layouts.
Test destination text before publishing a QR asset.

Reference standards and behavior

ISO/IEC 18004 specifies QR code symbology, and DENSO WAVE documents the four-module quiet zone. This page does not certify print quality or destination safety.

Notes

The page generates a 320-pixel SVG with medium error correction and a four-module quiet zone.
Long content creates denser codes that need more display or print area.
Scanning reliability depends on contrast, size, quiet zone, print quality, and camera conditions.

FAQ

Which error-correction level is used?

The SVG is generated with level M error correction.

How much quiet space is included?

The generator includes a four-module white quiet zone on every side.

Can I print the downloaded SVG?

Yes, but preserve the quiet zone, contrast, and square proportions, then scan the final printed output.

Why does a long value create a dense code?

More encoded data requires more modules and therefore more physical or screen area for reliable scanning.

Does generating a QR code verify the destination?

No. Check the exact encoded URL or text before distribution.
