Preview

For reliable scanning, keep strong contrast and test the final QR code before printing or publishing it.

What this tool does

Generate a QR code directly in your browser for a website link, plain text, email address, phone number or Wi-Fi network. Choose the image size and colors, preview the QR code, then download it as a PNG without sending the encoded content to ToolsDiary.

QR codes are a convenient way to move short pieces of information from a printed page or one screen to another device. A larger image does not increase the amount of data stored in the code, but it can make the code easier to print cleanly. Strong contrast between the QR pattern and its background is important for reliable scanning.

Useful for

  • Create a QR code for a website or landing page.
  • Share short text, email addresses or phone numbers in a scannable form.
  • Generate a Wi-Fi QR code so guests can copy network details more easily.
  • Download a PNG QR image for print, presentations, signs or digital content.

How to use it

  1. Choose the type of information you want to encode.
  2. Enter the required text, URL, contact detail or Wi-Fi information.
  3. Choose the QR image size and colors, then select Generate QR code.
  4. Test the preview with a QR scanner and download the PNG when it scans correctly.

Practical tips

  • Keep the background light and the QR pattern dark for the best scanning reliability.
  • Test printed QR codes at the actual size you plan to use before producing a large batch.
  • Use a complete URL including https:// when generating a website QR code.
  • The encoded content is processed locally in your browser and is not sent to ToolsDiary.

Frequently asked questions

Does ToolsDiary store the content I put in the QR code?

No. QR generation happens in your browser. The text or link you enter is not sent to ToolsDiary.

Can I generate a QR code for Wi-Fi?

Yes. Enter the network name, password and security type. You can also mark a network as hidden when needed.

Why will my QR code not scan?

Low contrast, a very small printed size, blur, heavy cropping or too much encoded text can reduce reliability. Try black on white, a larger size and shorter content.

Can I download the QR code?

Yes. The generated QR code can be downloaded as a PNG image.

Can I use a custom color?

Yes, but dark foreground and light background colors are the safest choice. Always test the result after changing colors.
