The short answer
Why use QR Scanner?
Browser APIs can handle many small file and device jobs without another upload step. The tool also shows a clear message when a permission or format is unavailable.
QR Scanner focuses on decoding a QR code from a file or camera image. The task uses browser storage, permissions, cryptography, or clipboard features. Sensitive values are not added to analytics.
The selected file stays in this browser tab and is released when you leave the page. Permissions and supported features differ by browser. Camera, clipboard, screen capture, and geolocation require HTTPS and a user action.
What QR Scanner does
Give it the input it needs
Drop, choose, or paste a supported file into QR Scanner. Decoding a QR code from a file or camera image. The source stays on your device; we work on a copy.
Run the small job locally
QR Scanner is for decoding a QR code from a file or camera image. The preview is the place to decide if the setting went too far. The original file is not overwritten.
Useful controls
Main controls: The value, permission, filename, password, or mode required by the selected utility. Working limit: File tools use the 50 MB image or 100 MB document limit; device tools depend on browser permissions. Watch the preview at full size before you save. A current desktop browser usually has more memory than a phone.
Download or copy the result
Export is a downloaded file, copied value, live preview, decoded text, or browser dialog. The download is a new file. Keep the original until you have opened the copy once.
Where QR Scanner fits
These are ordinary jobs where the focused controls save time. They also show where a full editor or a manual review may still be the better choice.
One-off tasks
Finish QR Scanner without installing a separate desktop utility.
Private inputs
Keep clipboard data, QR content, passwords, and camera frames out of analytics.
Browser workflows
Use native permissions and downloads so the result stays under your control.
