A photo or screenshot works — JPG, PNG, WebP, GIF, HEIC, and more
✓Free forever
✓Runs locally
✓No account

A barcode scanner with nothing paywalled
Reads 1D and 2D codes
UPC, EAN, Code 128, and more alongside QR, Data Matrix, Aztec, and PDF417 — not just QR.
100% private
Decoded entirely in your browser. The image you upload is never sent to a server.
Works from a photo or screenshot
A phone photo of a product label or a screenshot of a digital ticket both decode the same way.
Tolerant of angle and rotation
The underlying decoder handles a rotated, skewed, or slightly off-angle shot, not just a perfectly square one.
No account, no watermark
No sign-up, no usage limit, nothing added to the result — free the way it should be.
Instant result
Decoding finishes in under a second for a typical photo, right after it loads.
Scan a barcode in three steps
- 1
Upload a photo
Drop, paste, or browse for a photo or screenshot that contains a barcode or QR code.
- 2
It decodes automatically
The image is scanned the moment it loads — no button to click, no camera permission to grant.
- 3
Copy the value
The decoded text appears with its format (EAN-13, QR Code, Code 128, ...). Copy it with one click.
Built for how people actually run into a barcode
No physical scanner, no app install — a photo or screenshot is enough.
Check a product's UPC
Read a product barcode from a photo to verify or look up its code without a physical scanner.
Pull a ticket or boarding-pass QR payload
Decode the QR code on a screenshot of a digital ticket, boarding pass, or event pass.
Recover a code from an old photo or PDF export
Read a printed barcode or QR code that only exists as an image now, with no live scanner nearby.
Frequently asked questions
Is this barcode scanner really free?
+
Yes — decoding is unlimited, with no account, no watermark, and no daily cap. There's nothing paywalled here.
Is my image uploaded anywhere?
+
No. Decoding happens entirely in your browser using an open-source barcode-reading library — the photo you drop never leaves your device or touches a server.
What barcode formats are supported?
+
Every common 1D and 2D format: QR Code, UPC-A, UPC-E, EAN-8, EAN-13, Code 39, Code 93, Code 128, ITF, Codabar, RSS-14, RSS Expanded, Data Matrix, Aztec, PDF417, and MaxiCode.
Why didn't it detect my barcode?
+
The most common causes are a blurry or low-resolution photo, the code being too small/far away in the frame, glare or shadow across it, or a steep viewing angle. A closer, well-lit, in-focus shot usually fixes it.
What happens if my photo has more than one barcode in it?
+
The tool decodes the first one it locates. If you need a different code from the same photo, crop the image tighter around that code and re-upload it.
Does this work on a screenshot, not just a photo of a printed code?
+
Yes — a screenshot of a digital ticket, boarding pass, or QR code works the same way as a photo of a printed one, as long as the code is sharp and not scaled down too far.
