The camera opens, but the code still does not scan
Move the QR code into even lighting, hold the device steady for a moment, and avoid filling the frame too tightly. A small step back often gives the detector a cleaner view.

Fix the scanning problem, not the workflow.
These short sections focus on the situations users usually face when trying to scan a QR code quickly.
You need to read more than one QR code in the same image
Instead of cropping codes one by one, upload the full image. Multi-detection makes it easier to review separate results in one pass and compare them immediately.
You only have a screenshot, not the physical code
Use image upload instead of trying to show the screenshot to your webcam. Direct file scanning usually gives sharper input and avoids focus problems from screen glare.
A scanned result looks unfamiliar or too long
Open the detail view before taking action. It is safer to inspect the full content, format, timestamp, and parsed hints first instead of opening unknown links too quickly.
You are checking a stack of printed labels
Keep the camera running and let each code enter the frame cleanly. The saved history section helps you review past results without writing them down manually.
The code is partially damaged or printed small
Try a sharper photo with better contrast, then upload it. A still image often works better than a shaky live camera feed when the QR pattern is difficult to read.
You do not want to lose previous scan results
The browser-based history keeps records locally on your device, so you can return to recent scans, check details again, or remove entries you no longer need.
You need a fast scan page that is not overloaded
A focused layout helps you reach the camera, upload area, live results, and history quickly without searching through unrelated controls or oversized interface blocks.
Common questions
Straight answers for common QR scanning issues.
Low contrast, blur, glare, or a code that is too close to the camera can slow detection. Try steadier framing and softer light first.
Yes. When the browser supports multi-detection, each detected QR code is outlined and listed separately.
Yes. Drag and drop image files or click the upload area to select one or more images for QR scanning.
Your history is stored inside the browser on your device. It is not sent to an online account by this page.
It shows the decoded value, detected format, source, time, and simple parsed hints such as links, email patterns, phone data, or Wi‑Fi style strings when present.
The overlay helps confirm exactly which QR codes were detected in the frame, especially when multiple codes are visible at the same time.
Yes. Each saved item has delete controls, and you can also clear the entire history with confirmation.
You can still use image upload. The page will also show a friendly notice when live barcode detection APIs are unavailable.
