In their own words
EqualWeb PDF Tools
EqualWeb PDF Tools combines PDF accessibility checking, automated remediation, expert manual remediation, and an accessible in-browser viewer. Its checker performs more than 80 automated checks across eight categories and returns a score from 0 to 100 with a detailed report. AI remediation can address document structure, reading order, alternative text, tables, forms, fonts, text encoding, contrast, language, and metadata. Scanned PDFs can receive OCR and remediation, up to 400 pages. Batch processing supports up to 1,000 PDFs; individual files can be as large as 400 pages and 100 MB, though larger files may be uploaded and flagged during an audit. Word, Excel, and PowerPoint files can be converted to accessible PDF or HTML, and PDFs to accessible HTML. The product says it remediates and validates against WCAG 2.2, PDF/UA-1 and PDF/UA-2, Section 508, and EN 301 549. A REST API handles uploads, audits, reports, remediation, downloads, and batches, with access requested from EqualWeb. Auto AI Tag is optimized for English and Latin-script documents.
Nutrient DWS Accessibility API
Nutrient DWS Accessibility API processes PDFs to add accessibility tags and check conformance. It returns a tagged PDF with PDF/UA metadata and targets PDF/UA-1 (ISO 14289-1). Tagging covers H1–H6 headings, ordered and unordered lists, table rows and cells, reading order, annotations and decorative artifacts. The API accepts HTTP requests from any programming language, with quickstarts for Java, C#, JavaScript, Python and PHP. Nutrient reports 96.5% PDF/UA conformance across a validation corpus of 3,157 files. Its free plan costs nothing and includes 20 auto-tagged pages and 100 validations per month. Starter costs $79 a month for 200 pages and 1,000 validations; Professional is $249 a month for 1,000 pages and 5,000 validations; Business is $499 a month for 3,000 pages and 15,000 validations. Monthly quotas do not roll over, and requests in a quota category are blocked when that quota runs out unless a larger plan or pay-as-you-go is used. Auto-tagging does not guarantee full accessibility compliance, so Nutrient recommends QA, especially for sensitive or high-stakes documents.
