Our Accessibility Standards
Our commitment to true accessibility—not just compliance checkboxes, but documents that work for everyone.
Standards We Work To
PDF AA Compliance remediated documents meet or exceed these internationally recognised accessibility standards.
WCAG 2.1 AA
Web Content Accessibility Guidelines—the global standard for digital accessibility, referenced by regulations worldwide.
- Perceivable content
- Operable navigation
- Understandable structure
- Robust compatibility
PDF/UA-1
ISO 14289-1—the international standard specifically for accessible PDF documents and assistive technology compatibility.
- Tagged PDF structure
- Marked content sequences
- Logical reading order
- Alternative descriptions
Section 508 / ADA
U.S. regulatory requirements for federal agencies and organisations, including ADA Title II web accessibility deadlines.
- Federal compliance
- ADA Title II ready
- State & local support
- Audit documentation
Standards applied to real documents
Standards matter most when the source PDF is messy.
WCAG and PDF/UA are not abstract checklists here. They are applied to real document structures: product catalogues, map-heavy planning PDFs and long technical reports.
Catalogue remediation
Ungridded product cells, repeated images, prices and stock codes.
Map-heavy planning document
Maps, legends, place labels, links and long civic-policy content.
Long technical standards
Deep headings, tables, flowchart pages and long-document consistency.
WCAG 2.1 Criteria We Address
Our remediation process specifically targets these accessibility requirements.
Non-text Content
All images receive AI-generated alternative text that describes their content and purpose within the document context—not generic descriptions like "image" or "photo".
Info and Relationships
Document structure is programmatically determined through proper semantic tags: headings (H1-H6), paragraphs, lists, tables, and figures—all correctly nested and related.
Meaningful Sequence
Reading order is determined by visual position on the page—top to bottom, left to right—ensuring content is read in the order the author intended.
Bypass Blocks
Heading structure enables users to navigate between sections quickly, bypassing repetitive content and jumping directly to the information they need.
Page Titled
Documents include descriptive titles in metadata, displayed in the document viewer title bar so users immediately know what document they're viewing.
Headings and Labels
Headings are detected based on visual styling (font size, weight) and properly tagged with correct hierarchy (H1, H2, H3...) to describe the content that follows.
Language of Page
Document language is specified in metadata, enabling screen readers to use the correct pronunciation rules and language-specific processing.
Name, Role, Value
All document components have programmatically determinable names and roles that assistive technology can identify and communicate to users.
Our Technical Approach
True accessibility requires understanding how screen readers actually navigate PDF documents.
Semantic Structure Tree
We build a complete structure tree that defines the logical organisation of your document. This tree is what screen readers traverse to present content in the correct order.
Visual Reading Order
Reading order is determined by where content appears on the page—not by how the PDF file was constructed. Images, text, and other elements are ordered top-to-bottom, left-to-right, as a sighted reader would naturally read the page.
Meaningful Alt Text
Every image receives alternative text that describes not just what's shown, but why it matters in context. Our AI understands the document type and generates descriptions that convey the intended information.
Generic:
"image"
Descriptive:
"Bar chart showing quarterly revenue growth: Q1 $2.1M, Q2 $2.4M, Q3 $2.8M, Q4 $3.2M"
Screen Reader Tested
We test with real screen readers—not just validation tools. Compliance checkers can pass documents that fail for actual users. Our goal is true accessibility, not just checkbox compliance.

Our Commitment
Accessibility isn't just about compliance—it's about ensuring that everyone can access the information they need. We're committed to producing remediated documents that work with real assistive technology, for real users.
Continuous Improvement
We continuously update our remediation engine based on the latest standards and real-world screen reader testing.
Transparency
We're clear about what we can and can't remediate. Some documents may require manual review for complex elements.
User-Focused
Our measure of success isn't just passing a validator—it's whether a screen reader user can actually use the document.
