QR Code Scanner
Decode one or many QR codes from an image.
What does the QR scanner do?
The freeimgtool QR scanner takes an image containing one or more QR codes and returns the text encoded inside each one. If the code holds a URL, you can open it directly from the result panel. The detector is OpenCV's QR module, which finds and decodes QR codes from screenshots, posters, receipts, or printed materials. Multiple codes in the same image are all decoded.
No mobile app is needed. Drop an image into the page and you get the contents in less than a second. The same image is returned with green boxes drawn around every code found, which is useful for proving where a code was located in a printed sheet.
How to use it
- Click the upload box and pick an image (up to 5 MB).
- Click Scan QR.
- Copy the decoded text or click Open link.
- Optionally download the annotated image with green boxes around every code.
Why use this QR scanner
Phone QR apps are everywhere but they require pointing a camera at a screen, which is awkward when the QR is already on your laptop. Most online scanners want a webcam. This tool works on images that already live on your disk: a screenshot of a slide, a downloaded poster, a forwarded photo of a flyer. Quicker, and you keep both hands on the keyboard.
Who uses it
Office workers who got a QR in a slide deck or PDF. Marketers checking campaign codes before they print. Students decoding classroom links. Developers verifying their generated QR codes point to the right URL. Anyone who does not want to install another QR reader app on their phone.
Frequently asked questions
Is it free?
Yes. No signup, no daily limit on normal use. Display ads support the site.
What is the maximum upload size?
Five megabytes per image. A typical screenshot or phone photo is well under that. If the file is larger, compress it first with the image compressor.
Why did it find zero codes?
The QR is probably blurry, too small, or rotated past the detector's tolerance. Try cropping closer to the code or re-taking the photo with better light.
Can it scan multiple QR codes in one image?
Yes. Every detected code is shown separately with its own copy and open buttons.
Does it support barcodes?
Not yet. The current build is QR-only. Barcode (EAN, UPC, Code128) is on the roadmap.
Is the link checked for safety?
No. The tool only decodes the text. Before opening any QR URL, look at the link and decide whether you trust the source of the image.
Will my image be stored?
Uploads are kept only long enough to return the annotated image link and are removed automatically. Privacy policy has the details.
Can I scan a QR from my webcam?
Not in this tool. Use your phone's built-in camera for that case. This tool focuses on QR codes that already exist as image files.
