AccessiblePDF vs PDFix Desktop

AccessiblePDF is a web service from Palanisi Labs LLC for remediating PDF files. It tags uploaded PDFs, including scans, runs checks with veraPDF, and returns PDF/UA-1 files. A free compliance check is available before paid remediation. OCR for image-only pages is included in the $0.50, paid once plan, billed at $0.50 per page with no minimums. Results can include a tagged PDF with a PDF/UA identifier, bookmarks, before-and-after validation results, and a plain-English change list; accessible HTML is available on request. The Tag Editor places a live page beside its tag tree for editing reading order, tables, lists, headings, and alt text, with screen-reader preview and revalidation. Other plans cover manual remediation and team use. The service lists WCAG 2.1 AA, PDF/UA-1, Section 508, ADA Title II, EN 301 549, and AODA. Processing uses US regions, AES-256 at rest, and TLS 1.2+ in transit.

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.
