Scan QR codes and barcodes directly in your browser.

A QR code is only a container. Our scanner detects the content type and renders it as structured fields: URLs with a domain and safety hint, Wi-Fi codes as SSID, encryption and password, vCards as a contact with name, organisation, phone and email, SEPA payment codes with IBAN, BIC and amount. Email addresses, phone numbers, SMS, geo positions, calendar events and one-time passwords also become labelled fields instead of a single string.

That structure is the difference. If you scan a payment code you want to pay, not to read a BCD line. If you scan a vCard you want the contact. So the parsing is part of the tool — including check digits on product codes and GS1 application identifiers on Data Matrix payloads.

Open the page on the device you want to scan with — phone, tablet or laptop — and press “Start camera”. The browser asks for camera permission once; nothing turns on without you. You can also drag an image into the drop zone or paste a screenshot straight from the clipboard.

Hold the code so that all four corners are visible, roughly 15–20 cm away, and avoid glare. Decoding starts automatically as soon as a supported symbology is found. For uploaded images the round trip is usually under a second.

The result is parsed into a readable card: a link with its domain, Wi-Fi credentials, a contact card, or a product number with its check digit. Copy a single field or everything, and open links only after you have checked the destination.

The decoder is JavaScript running in your browser. Camera frames are drawn into a canvas and read there; uploaded images are read through FileReader. There is no upload endpoint for image data. That is an architectural decision, not a slogan: the application has no route that accepts image content.

To improve the tool we store anonymous counters only — detected format, payload category (Wi-Fi, product code and so on), interface language, and whether decoding succeeded. No decoded content, no filenames, no IP-based profiling. Scan history lives in your browser’s localStorage and is deleted with one click.

The usual suspects are low contrast, a code that is too small, or reflections on a laminated label. Steady the camera, zoom slightly, and make sure the quiet zone around the code is visible. For a photo, rotating it often helps the decoder find the alignment pattern.

For damaged codes, try a second angle. For product barcodes we validate the EAN-13 check digit and tell you immediately when the number cannot be genuine. Industrial Data Matrix payloads (VDA 4902, GS1) are also supported — and our label generator handles the printing side.
