Free Online QR Code Generator & Scanner

A very warm welcome to you! These days, QR codes are used everywhere — whether you want to share a website link, view a shop's menu, share your contact details, or provide information about an event. A QR code stores information in a small square pattern that can be quickly read by a camera or scanner.

For your convenience, SahiTool provides both a QR Code Generator and a Scanner in one place. You can create a new QR code from any text or URL and download it as a PNG image. Also, if you already have an image containing a QR code, you can upload it and easily read the hidden information by decoding it. By the way, if you want to convert any of your photos into a document, be sure to try our Image to PDF Converter.

What Is a QR Code Generator and Scanner?

A QR Code Generator converts any information you provide — such as a website address or a written message — into a special black-and-white square pattern. This pattern is designed so that any QR reader can quickly understand it.

A QR Code Scanner does exactly the opposite. It examines an image containing a QR code and extracts the hidden text or link for you. Having both features available in one workspace makes your work much easier.

How to Create a QR Code (Using the Generator)

1. First, click the QR Generator tab.
2. Enter your website link (URL) or any text you want in the input box.
3. Next, click the Generate QR Code button.
4. Your QR code will be generated and displayed in the preview area. Take a moment to check it.
5. Now, click Download QR PNG to save the image to your phone or computer.

Here is a small tip: whenever you create a QR code for a website, make sure to enter the complete URL. Also, scan it once to check that it works before printing it on a card, poster, or pamphlet.

How to Scan a QR Code from an Image

1. First, open the QR Scanner tab.
2. Select the image containing the QR code from your device.
3. Wait a moment for the image preview to appear.
4. Now, click the Scan QR Code button.
5. Once decoding is complete, the information contained in the QR code will appear in the Scan Result section.
6. You can easily copy this information by clicking the Copy Result button.

Keep in mind that scanning speed and success depend on the quality of your image. If the image is blurry, too small, or contains a damaged or partially cut-off QR code, scanning may be difficult. Always use a clear and sharp image. If you have a scanned document in PDF format and want to extract its text, you can also try our Scanned PDF to Text Online tool.

What Kind of Data Can You Put in a QR Code?

You can enter almost any text into our QR generator — such as your website address, a short message, contact information, product details, or any other text.

However, keep in mind that the more characters a QR code contains, the denser its pattern becomes. A denser QR code can sometimes take longer to scan. So, try to keep the information short, clear, and concise.

Which Images Can the Scanner Read?

Our scanner supports image formats that your browser can easily open, such as PNG and JPEG files.

For better results, always choose a high-quality image with good lighting and a clearly visible QR code. If your image is too large and you want to reduce its size, you can use our Image Compressor to make it smaller.

How Does This QR Code Generator Work?

When you enter text and click the button, a JavaScript QR library converts your information into a QR pattern. The entire process takes place directly in your browser and is usually completed in less than a minute.

This tool uses High Error Correction. The benefit is that even if your printed QR code gets slightly dirty or scratched, a scanner may still be able to read it correctly.

Once the QR code is generated, it appears on your screen, and you can download it as a PNG image with just one click.

How Does This QR Code Scanner Work?

When you select an image, your browser reads its pixels. Our QR decoder examines those pixels, recognizes the QR code pattern, and extracts the hidden data.

If the image is very large, our tool automatically adjusts it to a suitable size before scanning, helping reduce the impact on your browser's performance.
