Making PDFs Accessible for Everyone
2.2 billion people worldwide have a vision impairment. AA-compliant PDFs ensure they can read, navigate, and understand your documents — just like everyone else.
The Scale of Visual Disability
Visual impairment isn't rare — it affects people across every demographic, age group, and geography.

What Does an "Accessible PDF" Actually Mean?
An accessible PDF is one that assistive technologies — like screen readers — can read aloud in the correct order, with proper context for every element on every page.
Inaccessible PDF
When a screen reader encounters an untagged PDF, this is what the user hears:
"Blank."
"Image."
"43 72 61 66 74 65 64…" (garbled)
"End of document."
- No reading order — text jumps randomly between columns
- Images announced as "Image" with no description
- Tables read cell-by-cell with no row/column context
- Headings invisible — no way to navigate or skim
- Links announced as raw URLs or "click here"
AA-Compliant PDF
After remediation, the same document sounds like this:
"Heading level 1: Annual Report 2025"
"Image: Bar chart showing Q4 revenue of $12.3M, up 18%."
"Table with 4 columns and 8 rows. Row 1: Region, Q1, Q2, Q3…"
"Link: View full financial details (opens in new tab)."
- Logical reading order follows visual layout
- Every image has meaningful alt text
- Tables have row/column headers for context
- Headings create a navigable outline
- Links have descriptive, meaningful text
How People with Visual Disabilities Read PDFs
Understanding the tools that rely on AA-compliant documents.
Screen Readers
JAWS, NVDA, VoiceOver, TalkBack
Convert on-screen text into synthesised speech. They rely on the PDF tag tree to determine reading order, headings, alt text, and table structure.
Screen Magnifiers
ZoomText, Windows Magnifier
Enlarge portions of the screen for low-vision users. Proper tag structure ensures text reflows correctly at high magnification.
Braille Displays
Refreshable Braille Displays
Translate digital text into Braille characters via small pins. Tagged PDFs ensure the correct text is sent to the display in the right order.
High-Contrast Mode
OS-level & browser settings
Inverts or adjusts colours for users with low vision or light sensitivity. Tagged documents adapt; image-based PDFs break.
Text-to-Speech
Read Aloud, NaturalReader, OS TTS
Simpler than full screen readers but still need a tagged document to read in the correct order with proper structure.
Keyboard Navigation
Tab, arrow keys, shortcuts
Users who cannot use a mouse navigate by keyboard. Tags enable jumping between headings, links, form fields, and table cells.
What AA Compliance Specifically Achieves
Each remediation step maps to a real-world accessibility improvement for someone with a visual disability.
Semantic Tag Tree
Blind users with screen readers
Creates an invisible structural layer (headings, paragraphs, lists, tables) that screen readers parse to announce content type and hierarchy — "Heading level 2: Financial Summary" instead of just "Financial Summary".
Reading Order
All visually impaired users
Defines the sequence in which content is read. Without it, a two-column layout might read left-right across both columns instead of finishing column 1 first. Critical for multi-column reports.
Alt Text for Images
Blind users, users on slow connections
Provides a text description of every meaningful image. "Bar chart showing Q4 revenue of $12.3M, up 18% vs Q3" — not just "image" or nothing at all.
Table Headers
Screen reader users navigating data
Marks which cells are row headers and which are column headers so the screen reader can announce "Region: Northeast, Q1: $3.2M" instead of just "3.2M".
Document Language
Screen reader users in any language
Tells the screen reader which language the document is in, so it selects the correct pronunciation engine. Without it, English text might be read with a French accent.
Title & Metadata
All assistive technology users
Sets a meaningful document title (instead of "doc_final_v3.pdf") so screen readers can announce what the document is when it opens.
Real People, Real Impact
"When I get an untagged PDF, it's like someone handing me a blank sheet of paper. I know there's information there — I just can't reach it."
Sarah, University Student
Blind since birth, uses JAWS
"I can read large print, but most PDFs are 10pt. When I zoom in, the text reflows into nonsense unless the document has proper tags."
James, Government Employee
Low vision (macular degeneration)
"My bank sends statements as PDF. I used to have to call them every month to ask someone to read my own balance to me."
Maria, Retiree
Progressive vision loss, uses VoiceOver
Beyond Compliance: It's the Right Thing to Do
Yes, there are legal requirements, including ADA Title II deadlines in 2027 and 2028, Section 508 for federal agencies, and WCAG as the global standard. Non-compliance carries real risks: lawsuits, fines, and procurement disqualification.
But the real reason to make your documents accessible is simpler: everyone deserves equal access to information.
ADA Title II
State & local government digital content deadlines in 2027 and 2028
Section 508
Federal agencies — already enforced
WCAG 2.1 AA
International web standard — referenced by 40+ countries
PDF/UA-1
ISO 14289 — the technical standard for accessible PDFs
The Moral Case
Imagine opening a document that contains your medical test results, your child's school report, or your pension statement — and being told it's "blank."
That's the daily reality for millions of people when they encounter untagged PDFs. PDF AA compliance eliminates that barrier.
Our commitment:
Every PDF we remediate is one more document that a blind or low-vision user can read independently — without asking for help.
