Question 1

What is a QR Code?

Accepted Answer

QR Code (Quick Response Code) is a 2D barcode that can store URLs, text, contacts, WiFi credentials and other data. Phone cameras read the code by pointing at it, automatically opening the content.

Question 2

Can I use custom colors?

Accepted Answer

Yes — pick any color for the dots and any color (or transparent) for the background. To make sure the code stays readable, keep a good contrast: dark dots on a light background.

Question 3

Does a center logo affect scanning?

Accepted Answer

The QR standard has built-in error correction, so a small logo (up to ~30% of the area) usually scans fine. We recommend a square image with an opaque background for better visibility and always testing the scan before printing.

Question 4

Which formats can I download?

Accepted Answer

You can download as PNG (great for web and WhatsApp), SVG (vector, perfect for print and logos) or JPG (smaller, no transparency).

Question 5

Is my text/URL sent to a server?

Accepted Answer

No. All QR Code processing and generation happens locally in your browser. No data is sent to ToolboxHub or third-party servers.

Question 6

Is there a usage limit?

Accepted Answer

No. Generate as many QR Codes as you want — no signup, no watermark, no limit. It even works offline after the page loads.
