What PDFTagDog is
PDFTagDog is a PDF accessibility tool from ARGO, a WEMAP brand headquartered in Montpellier, France. It automatically adds structural tags for headings, paragraphs, lists, tables, and images, helping documents meet WCAG and PDF/UA requirements. The tool can correct reading order and lets users add, edit, and manage image alternative text. A built-in checker identifies remaining accessibility issues and guides compliance work. Batch processing handles multiple PDFs, while OCR extracts text from scanned documents before tagging. Bookmarks, internal links, external URLs, and form fields remain in the processed files. ARGO says the structural metadata is added behind visible content, so the appearance stays the same to sighted readers. It also says files are processed securely and not retained after tagging. PDFTagDog is available on the web or as self-hosted software; enterprise plans support on-premise deployment. The paid Custom plan is priced by volume and includes automated tagging, batch processing, WCAG 2.1 AA compliance, an accessibility checker, and priority support. Pricing is available on request.
