Xian's Tools provides two companion QR tools:

• QR Code EncoderQR Code Encoder: turn text or a URL into a QR image.
• QR Code Decoder: read the contents of a QR code in an image.

Both run in your browser. The content you enter and the images you select are not sent to a processing server.

Generate a QR code

1. Open QR Code Encoder.
2. Enter a URL or text, such as contact details or written connection instructions.
3. The QR code updates as you type, with no separate generation button.

• Include the URL scheme, as in https://example.com, so scanners can recognize it as a link.
• Keep the content short. More data produces a denser code, which may be harder to scan at small print sizes. A shortened URL can help with very long links.
• Test before printing with several phones, especially before a large print run.
• Chinese text is supported, along with other text you enter.

Common uses

• Add a portfolio or personal website link to a business card or résumé.
• Put a registration link on an event poster.
• Attach short written instructions to a physical item.

Read a QR code from an image

1. Open QR Code Decoder.
2. Click Select File and choose an image or screenshot containing the code.
3. Read the result and click Copy to ClipBoard to use it elsewhere.

If recognition fails

If the tool displays Something Wrong~, try the following:

• Use a clear image containing the complete code, ideally near the center.
• Avoid heavy filters or compression that blur the pattern.

If the code occupies only a small part of the image, use Image Cropper to isolate it before trying again.

When decoding an image is useful

• You received a QR image on your computer and do not want to scan it with a phone.
• You want to inspect the destination before opening it.
• You need to copy a long piece of text stored in the code.

Check unfamiliar links

A QR code can hide a phishing URL. Decode an unfamiliar code first and inspect the domain before visiting it. Avoid entering account credentials or payment details on an untrusted destination.
