What is PREP SmartHTML?

Most organizations manage thousands of inaccessible PDFs but have limited time and resources to address them before their next compliance deadline. Taking documents offline is not practical, and rebuilding every PDF for accessibility is simply not scalable.
That is why we built PREP SmartHTML.
Part of the PREP Enterprise Suite, PREP SmartHTML was designed to help organizations make existing content accessible quickly, efficiently, and at scale. It automatically scans your website, detects every PDF, and delivers an accessible HTML alternative directly inside the browser in a purpose-built modal. Your users get a clean, accessible HTML experience every time they click a PDF link on your website.

An Interim Pathway, Not a Permanent Fix

Designed to make your existing PDFs accessible now, while full remediation continues in the background, across your document library.

Conversion Alone is Not Enough

Organizations with existing PDF-to-HTML conversion tools still come back to remediate. The PDFs remain. Users still access them.

The Source Still Needs Attention

An HTML alternative does not resolve the accessibility challenge at the file level. The PDF itself still needs to meet accessibility standards.

See How PREP SmartHTML Works

PREP SmartHTML scans your website, converts every PDF into accessible HTML, and delivers it directly in the browser. The entire setup takes just one day.

Why PREP SmartHTML is a Practical Solution for Legacy PDFs?

A browser-based tool that keeps every document accessible while PDF remediation continues, so no user is ever left without access.

Fast Paced Accessibility at Scale

  • Intercepts every PDF click and serves an accessible HTML alternative directly in the browser, while keeping the original PDFs in place.
  • Deploy once, and every PDF on your website gets an accessible alternative, automatically. Eliminate any manual or document-by-document effort.

Deploys in One Line of JavaScript

  • Add it to any public-facing website, and PREP SmartHTML is ready to go. No backend access, no CMS changes, no infrastructure overhead.
  • Once live, PREP SmartHTML manages itself. Lightweight to run, with end-to-end setup support from our team every step of the way.

Designed for Complex Documents

  • Powered by proprietary algorithms and AI models, SmartHTML accurately processes PDFs of any complexity, including tables, grids, and multi-column layouts.
  • Supports formula and MathML content for technical, academic and government documents, with built-in OCR for scanned and handwritten files.

Readable, Navigable, Accessible HTML

  • Users get structured, navigable HTML instead of a raw browser PDF, with full keyboard navigation, screen reader compatibility, and focus management built in.
  • PREP SmartHTML does not try to fix your PDF in the browser like an overlay. It generates a separate, fully accessible HTML version directly in your browser window.

Aligned With Compliance Standards

  • Delivers accessible HTML that aligns with WCAG 2.2 AA, Section 508 and ADA Title II requirements.
  • Designed to support compliance workflows across government, higher education, enterprise, and healthcare.

Enterprise-Grade Security

  • Every interaction with SmartHTML is protected by TLS 1.2+ encryption and AES-256 data security. Your PDF files are never retained after processing.
  • Built on enterprise hosting with full audit logging. No cookies are used and visitor data is never collected, tracked, or shared with third parties.

Frequently Asked Questions

No. PREP SmartHTML is an interim accessibility pathway, not a replacement for PDF remediation. It delivers accessible HTML alternatives to PDFs while your organization continues working toward full remediation. The PDFs themselves still need to be remediated to meet Section 508, WCAG 2.2 AA and ADA Title II standards at the source.
PREP SmartHTML delivers an accessible HTML version of your PDF directly in the browser. It is the right choice when you have a large backlog and need an accessible pathway now, when remediation is underway but not yet complete, or when you need interim access without removing documents from public view.
