How it works
Three steps, zero friction.
Everything happens locally in your browser — images and QR contents never touch a server.
- 01
Choose your input.
Use your device camera, upload an image from your gallery or local storage, or paste a screenshot straight from the clipboard with Ctrl+V.
- 02
Instant decoding.
A layered engine tries the native barcode API first, then falls back to a battle-tested decoder with contrast, inversion, and upscale retries for stubborn codes.
- 03
Act on the result.
Links open with a safety check, WiFi codes reveal the password, contact cards save as .vcf files, and events download as calendar entries.
Why QRCodeScanner
Built to be better.
Everything a QR scanner should do — and the thoughtful extras others skip.
Layered decode engine.
The native BarcodeDetector API is tried first, then a proven fallback decoder with automatic inversion, contrast, and upscale retries.
Paste straight from clipboard.
Screenshot a QR code anywhere, then press Ctrl+V or ⌘V on the page. Drag-and-drop works anywhere too — no need to aim at a tiny drop zone.
Smart results, not just text.
WiFi codes show the password with copy buttons, contacts export as .vcf, events download as .ics, and locations open in Maps.
Link safety check.
Scanned URLs are inspected for bare IP hosts, punycode lookalikes, embedded credentials, and risky shorteners before you open them.
Dark mode & local history.
A full dark theme respects your system preference, and your last 30 scans stay in this browser only — clearable any time.
