QR & Barcode Reader
Read a QR code or barcode from a picture or your camera, and see exactly what is inside it — the full link, the Wi-Fi password, the contact details — before you act on it.
What it does
QR & Barcode Reader reads the whole document before doing anything, so what comes back is either valid output or a specific error with the position that caused it — not a partially rewritten file.
When you need it
Usually when something has already gone wrong: a config file an application will not load, an API response that has to be read by a human, or an export that has to be checked before it goes anywhere near a database.
Limits and caveats
Key order is preserved as it appears in the input. Very large documents are limited by your device's memory rather than by an upload cap, since the parsing happens locally. Everything happens in your browser, so the file never leaves your device.
How to qr & barcode reader
- Drop a photo or screenshot of the code, or use your camera.
- Read what is actually inside it.
- Open it only if you want to.
Frequently asked questions
- Why not just point my phone camera at it?
- Because your phone opens the link. A QR code is a link you cannot read, and every piece of advice about not tapping unknown links stops applying the moment the link is a picture. This shows you the destination first — the real host, the whole address — and only then offers to open it.
- Which codes can it read?
- QR codes everywhere. On Chrome, Edge and Android it also reads EAN-8, EAN-13, UPC, Code 39, Code 128, ITF, PDF417, Data Matrix and Aztec, using the browser's own decoder. Safari and Firefox do not offer that decoder yet, so there it is QR only.
- Does the camera image go anywhere?
- No. The camera frames are decoded in this tab and never leave it — nothing is recorded, uploaded or kept. Closing the page ends it.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
