Can I scan a QR code with my phone camera?

Yes. Tap Scan with camera and allow access; on a phone it uses the rear camera. The video is read on your device and never sent anywhere.

Which image files can I scan?

JPG, PNG, WebP or GIF, such as a screenshot or photo of a QR code. On a computer you can also paste an image with Ctrl+V. The image is not uploaded.

What does it show for a Wi-Fi or contact QR code?

It lays out the fields: network name, security and password for Wi-Fi, or name, phone, email and more for a contact. Links, emails and phone numbers can be opened directly.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Are my files uploaded?

No. Your files are opened and processed inside your browser and are not sent to LibraTool. Some tools first download a processing engine or AI model to your browser; that download contains no data of yours.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install. Very large files can be slow or run out of memory on a phone, so use a computer for those.

How It Works

QR codes are decoded entirely in your browser using a tiny pure-JavaScript library (~30 KB). No image is ever uploaded — even when you use the live webcam scanner.

1
You drop an image or start the webcam
For file decoding: the image is loaded into memory. For live scanning: your camera feed stays on your device — frames are captured locally and never transmitted.
2
Pixels are analyzed by the jsQR library
jsQR scans the pixel data looking for the QR code's distinctive finder patterns (the three large squares in the corners). Once found, it decodes the data matrix into text.
3
The decoded text is shown with a type hint
The tool detects whether the QR contains a URL, Wi-Fi credentials, vCard, email, etc. and labels it accordingly. You can copy or follow safe URLs directly.

Webcam scanning never sends video to any server. The camera stream lives entirely in your browser, gets read frame-by-frame, and is discarded as soon as you stop scanning.
