Technical notes
PDF pages are first rasterized to images, then each image is scanned for barcodes and QR codes. That's why render DPI matters: too low can miss small barcodes, too high slows the job. For dense 1D barcodes, 200-300 DPI usually works well.
Results are tied to a page number, so in a multi-page document you can track which barcode is on which page. If a page has several codes, they are each listed on a separate row.
Both text-based (digital) and scanned (image) PDFs are supported; in both cases the page is converted to an image and scanned. For very large documents, choosing a page range speeds up processing.
All decoding runs in your browser; the PDF is never uploaded. For single images use the image barcode reader, and to parse GS1-128 element strings use the GS1-128 parser.
Frequently asked questions
Yes. Even if a page has no text it is rasterized and scanned, so barcodes in scanned documents can still be read.
