PDF Tools - PDF Accessibility Checker, AI Remediation & Accessible Viewer

EqualWeb PDF Tools make documents accessible automatically - checking, AI-remediating and serving accessible PDFs that meet WCAG 2.2, PDF/UA-1 and PDF/UA-2 (ISO 14289-1 and ISO 14289-2:2024) and Section 508.

What it is: A suite of PDF accessibility tools: a checker, AI auto-remediation, expert manual remediation, and an accessible in-browser PDF viewer.
Who it's for: Government, finance and education teams that publish high volumes of PDF documents.
What it solves: Audits PDFs with 80+ automated checks, then remediates the whole document - structure and reading order, alt text, tables, forms, fonts and text encoding, color contrast, language and metadata - and publishes accessible documents at scale.

Low-contrast text? The PDF checker flags every WCAG contrast failure - and AI remediation recolors failing text automatically.

Check, fix, publish

From a broken PDF to an accessible one

Upload a document and the AI rebuilds it end to end: it builds or repairs the full tag structure - headings, tables, lists, reading order - writes alt text, labels form fields and sets tab order, embeds fonts and fixes text encoding so screen readers read the real text, corrects low-contrast colors, and sets the language, title and PDF/UA identifier. Complex files go to certified experts, and you publish the accessible result anywhere.

Questions

Accessible PDFs, explained

How do I make a PDF accessible?

Upload the PDF to EqualWeb PDF Tools. The AI audits it with 80+ checks, then remediates every layer of the document: it builds the tag structure where none exists and repairs it where it's broken - headings, tables and lists, reading order - writes image alt text, labels form fields and links and sets tab order, embeds fonts and fixes text encoding so screen readers read the real text, corrects color contrast, and sets document language, title and metadata. You get an accessible PDF compliant with WCAG 2.2, PDF/UA-1 & PDF/UA-2 and Section 508 - automatically re-audited, with a report and a numerical score. Complex files can be finished by EqualWeb's certified experts.

What standards do accessible PDFs need to meet?

Accessible PDFs are typically required to meet WCAG 2.2, PDF/UA-1 and PDF/UA-2 (ISO 14289-1 and ISO 14289-2:2024), Section 508 and EN 301 549. EqualWeb PDF Tools remediate and validate documents against all of these - including PDF/UA-2, the 2024 revision of the standard.

Can EqualWeb remediate scanned (image-only) PDFs?

Yes. Digitally created PDFs with live text go straight through AI remediation. Scanned, image-only PDFs are first converted with OCR - turning the page images into tagged, readable text - then remediated like any other document. Unusually complex scans can be finished by EqualWeb's certified experts.

What are the file limits?

Upload non-scanned PDFs up to 100 MB and 400 pages per file, and up to 1,000 PDFs at a time. Standard page sizes from 6" to 17.5" in either dimension are supported. Audit operations process documents up to 400 pages - larger PDFs upload but are flagged when audited. Remove hidden content such as JavaScript from a PDF before processing, and for InDesign PDFs address any missing fonts by adding the font files to the fonts folder. The Auto AI Tag is currently optimized for remediating English and Latin languages.

What do I receive after PDF remediation?

You receive an accessible PDF compliant with WCAG 2.2 / PDF/UA / Section 508, a detailed report of what was fixed and what remains, and a numerical accessibility score; Managed clients also get a formal conformance validation.
