Legal exposure
Accessibility lawsuits are surging — PDFs are the #1 cause
The most common trigger for ADA-related litigation is an inaccessible document or PDF. Remediation is no longer optional — it's legal protection.

Why RemeDocs
HTML overlays aren't real remediation
Some tools wrap your PDFs in an HTML transcript and call it done. That means your actual PDF file remains inaccessible — it can't be downloaded, emailed, or opened offline in a compliant state.

FAQ
Common questions
Everything you need to know before getting started.
RemeDocs handles all common PDF types: text-based documents, scanned image PDFs, mixed documents, multi-column layouts, forms, and documents with tables and figures. Very complex or highly custom layouts may require human-in-the-loop review for maximum accuracy.
Every image in your document is analyzed by a vision AI model that generates a meaningful description of the image's content and purpose. On Professional and Enterprise plans, these descriptions are reviewed in a human-in-the-loop queue before being written into the final PDF.
Yes. Documents are encrypted in transit (TLS 1.3) and at rest. Files are processed in isolated environments and automatically deleted after 24 hours unless you opt for storage. Enterprise customers can deploy RemeDocs on-premise with zero data leaving their infrastructure.
Yes. The RemeDocs REST API accepts a PDF upload and returns a remediated file. Professional and Enterprise plans include full API access with documentation, SDKs for Python and Node.js, and webhook support for async processing. See our API docs for details.
RemeDocs produces documents that conform to WCAG 2.1 AA, PDF/UA, Section 508, and ADA technical standards. However, accessibility compliance also depends on content quality and context. We strongly recommend human review for legally sensitive documents. RemeDocs is not a substitute for legal counsel.
Most documents under 50 pages are remediated in under 30 seconds. Larger documents or those with many scanned pages requiring OCR may take 1–3 minutes. The API supports async processing with webhooks for long-running jobs.
Automated remediation applies all fixes programmatically — fast and scalable. Human-in-the-loop (Pro and Enterprise) routes the remediated document through a review queue where an accessibility specialist verifies alt text, reading order, and complex tables before delivery. Recommended for high-stakes public documents.
Testimonials
Trusted by compliance teams
From government agencies to enterprise legal departments — teams using RemeDocs cut remediation time from weeks to seconds.
★★★★★
"We had over 4,000 legacy PDFs on our public portal. RemeDocs processed the entire backlog in a single afternoon. What would have taken our team months — and a six-figure remediation contract — was done before end of day."
RL
Rachel Loomis
Digital Accessibility Director, King County Government
★★★★★
"The API integration was painless — we hooked it into our document management system in a day. Now every PDF that gets published is automatically remediated before it ever goes live. It's become invisible infrastructure."
MO
Marcus Osei
Senior Engineer, LexDocs Platform
★★★★★
"We were hit with an ADA complaint about our annual report PDFs. RemeDocs remediated three years of filings in under an hour and generated audit certificates for each one. The complaint was resolved within a week."
ST
Sofia Tran
General Counsel, Meridian Financial Group
★★★★★
"Other tools gave us an HTML page and called it remediation. RemeDocs actually fixes the PDF — we can download it, email it, and it passes every checker we've thrown at it. That's the difference."
JB
James Beaumont
Web Accessibility Lead, State of Colorado OIT
★★★★★
"We manage documents for 200+ nonprofit clients. The bulk upload and API made it possible to scale remediation across all of them without adding headcount. RemeDocs paid for itself in the first billing cycle."
AK
Anjali Kapoor
CTO, CivicReach Agency
★★★★★
"Reading order and alt text quality blew me away. I ran some of our most complex multi-column policy briefs through it and tested them personally with NVDA. Best automated output I've seen from any tool."

Under the hood
How RemeDocs works
A three-phase pipeline that turns any PDF — scanned, complex, or legacy — into a fully compliant accessible document in seconds.
01
Analysis
Phase 1
Document intelligence & structure detection
Before any remediation begins, RemeDocs builds a full map of your document — page layout, content types, reading flow, and existing tag structure. This analysis phase is what makes the downstream fixes accurate rather than guessed.
✓
OCR & text extraction — Tesseract-powered OCR for scanned pages, PyMuPDF for native text. Handles handwriting, mixed content, and multi-language documents.
✓
Layout classification — Detects single-column, multi-column, table-heavy, form, and mixed layouts. Each gets routed to the appropriate remediation path.
✓
Reading order inference — Uses spatial analysis and semantic heuristics to establish logical content flow, even in complex multi-column and sidebar layouts.
✓
Existing tag audit — Evaluates any pre-existing tags for accuracy. Broken or malformed tags are flagged and re-built rather than simply preserved.
✓
Image inventory — Catalogs every image, figure, chart, and decorative element. Each is classified as informational or decorative to guide alt text generation.
02
Remediation
Phase 2
AI-powered accessibility fixes
With the document map in hand, RemeDocs applies a full suite of accessibility fixes — structural tagging, alt text generation, heading hierarchy, and metadata — programmatically and at scale.
✓
Full PDF tagging — Builds a complete tag tree: Document, Part, Article, Section, P, H1–H6, Table, TR, TD, Figure, and Span tags per the PDF/UA specification.
✓
AI alt text — Every informational image is described by a vision model (Claude). Descriptions capture content, context, and purpose — not just visual appearance.
✓
Heading hierarchy repair — Detects visual heading styles and maps them to semantic H1–H6 levels. Skipped levels and ambiguous headings are resolved automatically.
✓
Table structure — Identifies header rows, scope attributes, and merged cells. Complex tables get TH/TD mapping with proper scope and id/headers relationships.
✓
Link text remediation — "Click here" and bare-URL links are rewritten to be descriptive. Anchor text is inferred from surrounding context.
✓
Language & metadata — Document language is set in XMP metadata and the PDF catalog. Title, author, and subject are populated or corrected.
03
Output
Phase 3
Compliant file delivery & audit trail
The remediated PDF is packaged to the PDF/UA-1 specification, validated against WCAG 2.1 AA, and delivered with a full audit certificate. Every fix is logged for traceability.
✓
PDF/UA-1 packaging — The output PDF is written to ISO 14289-1 (PDF/UA) standard using pikepdf. DisplayDocTitle is set, tab order is standardized, and the XMP metadata includes the PDF/UA identifier.
✓
Automated validation — The output is checked with PAC 2024 and VeraPDF rules before delivery. Issues that can't be auto-resolved are flagged in the audit report.
✓
Audit certificate — Every document gets a signed PDF/UA conformance certificate with a timestamp, issue log, fix summary, and test results. Suitable for legal and compliance records.
✓
API delivery — Remediated files are returned via REST API, S3-compatible storage, or webhook callback. Async processing with job tracking for large batches.
