Askem PDF Fixer vs PDFix Desktop

Askem PDF Fixer is a paid web service that checks PDF accessibility, applies automatic corrections, and validates results against PDF/UA-1 and applicable WCAG 2.1 AA criteria. Fixes cover document structure and tags, reading order, image alternative text, metadata, artifacts, and untagged content. Every document receives a validation result and a per-document record; Askem says more than 9 in 10 documents pass. A single upload accepts PDFs up to 500 pages and needs no integration, project, or procurement process. Batches can contain up to 200,000 documents. Files can be processed in any language, with the language set in PDF metadata. Scanned PDFs, complex tables or infographics with ambiguous meaning, context-dependent alternative text, and forms with conditional logic are flagged for manual handling. Documents are processed and stored on EU infrastructure and are not transferred outside the EU. OCR and API access are not available. Pricing is on request, with a 20-minute call offered for prospective customers.

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.
