QR Scanner

Upload a screenshot, photo, or saved poster to decode a QR code locally in your browser.

Scan source

Use image upload or live camera scanning.

Choose or drop a QR image

Drag and drop an image here or click to choose a file.

Choose image

Running in compatibility mode for this browser. Scanning still works, but detection may be slower than Chromium.

How it works

Choose a clear image, let the browser decode it locally, and copy the result once the code is found.

• Best for QR screenshots, menu photos, payment posters, and links.
• The scan stays on your device.
• Replace the image whenever you need a different file.

Tool introduction

What QR Scanner does

The QR Scanner reads QR codes from uploaded images so you can decode a link or text without using a camera app or a separate mobile scanner.

Your data is processed in your browser where possible. We do not intentionally store your files or input on our server.

Privacy and processing

How your input is handled

The QR Scanner reads the uploaded image in your browser and does not need a remote scan service.
The decoded text stays on your device unless you copy or share it yourself.
Always confirm the destination before opening a decoded link from an unknown image.

How to use QR Scanner

1Open the ChlatWork QR Scanner.
2Choose or drop an image that clearly shows the QR code.
3Wait for the browser to read the image and decode the result.
4Copy the detected text or open the link if it is a URL.
5Replace the image and scan again if the first file is not the one you need.

Why people use this tool

It is useful when a QR code already exists in a screenshot, saved photo, or shared poster image.
It keeps the scan local in your browser instead of sending the image to a remote server.
It works well for support cases, saved receipts, menu screenshots, and shared documents.
It is faster than retyping long links from a picture.
It is mobile friendly, so you can test QR images from a phone or tablet.

Practical use cases

A support team scans a screenshot of a payment QR sent by chat.
A cafe scans a saved menu poster before reusing the destination link.
A worker decodes a QR inside a photo that was forwarded in a group chat.
A student checks the link from a QR included in class notes or slides.
A seller verifies a QR on a product photo before printing new labels.

Output verification checklist

Test at least one real sample before sharing or printing.
Open the output on another device or app to confirm compatibility.
Check names, numbers, dates, and links for typing mistakes.
Keep the original file or text until the final output is accepted.

Tips and limitations

Use a clear image with the QR code filling most of the frame.

Avoid blurred or cropped photos because the scanner needs the full code pattern.

If the code is tiny, zoom in or crop the image before scanning.

Test the decoded link before sharing it further.

If an image contains multiple QR codes, scan one at a time for the cleanest result.

Common mistakes to avoid

Uploading a blurry image where the QR squares are too soft to detect.
Cropping off part of the QR code and leaving the finder corners incomplete.
Scanning a decorated image where the code is too small or covered by graphics.
Assuming the first decoded link is correct without checking the destination.

FAQ

Can I scan a QR code from a screenshot?

Yes. Screenshots, saved images, and photos all work as long as the QR code is clear enough for the browser to detect.

Do I need to upload the image to ChlatWork?

No. The scanner is designed to work in your browser, so the image is processed locally on your device.

What if the QR code is not found?

Try a clearer image, crop closer to the code, or make sure the picture is not blurry, rotated badly, or covered by design elements.

Can it decode links and text?

Yes. QR codes can contain links, plain text, and other short data, and the scanner will display the decoded value.
