PDFix Desktop
PDFix Desktop is a desktop application for PDF accessibility remediation, auto-tagging, and validation against PDF/UA and WCAG standards. It runs on Windows, macOS, and Linux and offers automated scans as well as manual review tools. Four auto-tagging methods are available: basic tagging, templates generated from preflight checks, AI-generated templates, and predefined layout templates. A visual Accessibility Panel lets users refine tables, headings, and alternative text. Its built-in veraPDF engine checks PDF/UA-1 and PDF/UA-2, WCAG 2.1 and 2.2, Section 508, and the European Accessibility Act; audit reports can be exported in HTML, XML, or JSON. The free download exposes all features, but saved PDFs may contain redacted content and a watermark. Desktop Pro costs $599 a year, and Desktop Enterprise costs €1,000 a year; Enterprise adds batch processing with layout templates. The product page says validation is local and documents are not uploaded to a server. PDFix cautions that human checks and intervention remain necessary for full compliance.
