Case studies

Real remediation proof for complex PDF documents.

These examples use three test documents from the pdfaa.ai remediation pipeline: a product catalogue, a planning document with maps, and a long technical standards document with tables. Each case shows the source complexity and the certificate evidence generated after remediation.

Australia Post Product Catalogue

Catalogue and retail layout

Bass Coast Planning Statement

Maps, links and planning content

CFA Medical Standards

Long-form technical standards

Case 1

12 pages, retail catalogue layout

Australia Post Product Catalogue

A dense product catalogue with free-form placement, product imagery, repeated branding, prices, stock codes and short descriptions that must remain associated with the correct item.

Starting complexity

Free-form catalogue cells rather than a clean table or single-column article layout.

Product images, product names, prices and stock codes must be grouped without interleaving unrelated cells.

Repeated brand marks and duplicate-looking product images need suppression without losing meaningful image descriptions.

Case 2

69 source pages, remediated into 136 accessible pages

Bass Coast Planning Statement

A long government-style planning document with maps, spread pages, place labels, tables, links and dense policy text. The main accessibility risk is turning visual map detail into useful screen-reader structure without reading every label fragment as noise.

Starting complexity

Maps and diagrams need meaningful descriptions while suppressing fragmented internal labels.

Double-page spread handling turns broad planning pages into accessible single-page reading units.

Links, headings and tables must stay navigable across a long civic document.

Case 3

144 pages, long-form standards document

CFA Medical Standards

A 144-page technical document with a deep heading hierarchy, tables, table of contents links, clinical classifications and flowchart-style pages. The remediation challenge is preserving structure at scale without flattening the document into plain text.
