About PDF Barcode Scanner
PDF Barcode Scanner reads and decodes all barcodes and QR codes embedded in or printed on PDF pages — extracting code values, symbology types, and page locations into a structured CSV export. Whether you're auditing shipping labels, processing inventory documents, reading QR codes in forms, or extracting product UPCs from catalogs, the tool processes each PDF page as a high-resolution image and runs ZXing (the de facto open-source barcode library) to detect all supported symbologies. All processing is browser-side — the PDF is rendered page-by-page via pdf.js at 200 DPI, each page image is passed to ZXing's WebAssembly scanner, and results are aggregated. No image or PDF data is sent to any server.
Most barcode scanners handle one image at a time. This tool processes entire multi-page PDFs in one operation — scanning every page and building a complete inventory of every barcode found, with page number, barcode type, position, and decoded value in a downloadable CSV. Supports 20+ symbologies including QR, DataMatrix, PDF417, and all 1D barcodes.
Who Uses This Tool
- Auditing shipping label PDFs to extract all tracking numbers into a spreadsheet
- Processing inventory count sheets to read product UPC codes from printed PDFs
- Extracting QR code URLs from forms, tickets, and marketing materials
- Verifying that all barcodes in a print-ready PDF are scannable before going to press
- Batch extracting serial numbers from equipment inventory PDFs
- Reading patient ID barcodes from medical form PDFs for EHR data entry
How to Use Scan Barcodes from PDF
- Step 1: Upload your PDF (shipping label, inventory sheet, form, or product catalog)
- Step 2: The tool renders each page and scans for all barcode symbologies
- Step 3: Review the results table showing each barcode's page, type, and value
- Step 4: Download the CSV or copy values to clipboard
Frequently Asked Questions
What barcode types does it detect?
QR Code, Data Matrix, PDF417, Aztec, Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-A, UPC-E, Codabar, ITF, RSS-14, and MaxiCode. Most common retail and industrial symbologies are supported.
Can it read barcodes from scanned PDFs?
Yes — scanned PDFs are rendered as images before scanning. Quality depends on scan resolution; 300 DPI scans produce the most reliable barcode reads.
Does it read barcodes from photos of physical documents?
If you've converted a photo to PDF, yes. For direct photo scanning, use a dedicated barcode scanner app which can handle perspective distortion better.
Is there a limit on pages per PDF?
No hard limit, but processing speed scales with page count. A 100-page shipping manifest typically completes in 30–60 seconds.
