Free Online Barcode Scanner: Decode Any Barcode or QR Code from a Photo

Ever had a barcode you needed to read but no scanner app handy — just a photo on your phone or a screenshot from a PDF? Nutilz Barcode Scanner decodes barcodes and QR codes straight from an uploaded image, right in your browser, with no app install and no signup.

What it does

Upload any image containing a barcode — a product photo, a screenshot, a scanned label — and it detects and decodes it instantly. It supports a wide range of formats:

• QR codes
• Retail codes: EAN-13, EAN-8, UPC-A, UPC-E
• Code formats: CODE 128, CODE 39, CODE 93, Codabar, Interleaved 2 of 5
• GS1 DataBar (standard and expanded)
• PDF417
• ISBN-10 / ISBN-13

If an image contains multiple barcodes, it detects and lists all of them in one pass.

How to use it

1. Go to nutilz.com/barcode-scanner
2. Drag and drop an image (or click to browse) — JPEG, PNG, WebP all work
3. Click scan
4. The decoded value and barcode type appear immediately, with a one-click copy button

That's it — no camera permissions needed, since it works from any image file you already have.

Why it's useful

• Inventory and cataloging: quickly pull product codes from photos when building a spreadsheet, instead of retyping long numbers by hand
• Checking product authenticity or specs: decode a UPC/EAN to cross-reference against a product database
• Recovering data from old scans or screenshots: when the original barcode isn't physically available anymore, a saved image is enough
• Developers testing barcode generation: verify that a barcode your code generated actually encodes the value you expect, without needing a phone scanner app
• Library and book cataloging: decode ISBN barcodes from cover photos

Since it just reads an uploaded image, it also works well for barcodes that are hard to scan live with a shaky phone camera — a well-lit still photo often decodes more reliably than a live camera feed.
