Before you rely on this

The image is drawn by the public api.qrserver.com service, so what you enter — Wi-Fi password included — is sent there. In print, a QR code fails to read if each module is too small or the four-module quiet zone is missing — and people cannot see where the encoded URL leads before opening it.

Tool Overview & Key Purpose

Turn a website link, plain text or Wi-Fi login (network name and password) into a QR code, recolor the code and background, and download it as a 300×300 PNG.

Step-by-Step Usage Instructions

1STEP 1

Choose one of the three tabs: URL, Text or Wi-Fi.

2STEP 2

Enter the link or text, or on the Wi-Fi tab enter the network name (SSID) and password.

3STEP 3

Pick the code (foreground) and background colors; the preview updates right away.

4STEP 4

Download the PNG or copy the encoded text. Save settings you reuse to the history.

Pro Tips & Key Considerations

Ensure high visual contrast; dark code on light background works best.The image is drawn by an outside service (api.qrserver.com), so what you type — including a Wi-Fi password — is sent there. Avoid sensitive data.
