All tools are client-side. No login required.

How to use

Enter your text or URL in the input box.
Pick a size (in pixels), margin and error correction (ECC).
Click Generate to preview the QR. Click Download to save as PNG.

What is error correction?

QR codes can still be read when partially damaged. ECC controls that tolerance: L (low), M (medium, default), Q, and H (highest). Higher ECC increases QR density.

Tips

For print, choose a larger size (≥ 512px) and higher ECC (Q/H).
Keep contrast high: dark QR on light background works best.
Always test your QR using multiple devices before sharing/printing.
