AccessiblePDF vs PAVE 2.0

AccessiblePDF is a web service from Palanisi Labs LLC for remediating PDF files. It tags uploaded PDFs, including scans, runs checks with veraPDF, and returns PDF/UA-1 files. A free compliance check is available before paid remediation. OCR for image-only pages is included in the $0.50, paid once plan, billed at $0.50 per page with no minimums. Results can include a tagged PDF with a PDF/UA identifier, bookmarks, before-and-after validation results, and a plain-English change list; accessible HTML is available on request. The Tag Editor places a live page beside its tag tree for editing reading order, tables, lists, headings, and alt text, with screen-reader preview and revalidation. Other plans cover manual remediation and team use. The service lists WCAG 2.1 AA, PDF/UA-1, Section 508, ADA Title II, EN 301 549, and AODA. Processing uses US regions, AES-256 at rest, and TLS 1.2+ in transit.

PAVE 2.0 is a free, web-based, AI-powered tool for remediating PDF documents. Developed by the ICT Accessibility Lab at the ZHAW Institute of Computer Science, it guides users through an eight-step workflow. Users can group and adjust regions such as paragraphs, headings, figures, tables, formulas, and captions. They can set the reading order of page regions for screen readers, organize heading levels, and define table and list structures. The tool supports adding or editing alternative text for figures and mathematical formulas. A final check lets users review results and add metadata; the page states that an accessible PDF needs at least a title, author, and language. PAVE 2.0 lists PDF tagging, reading-order, alternative-text tools, and PDF/UA support. It is not suitable for confidential information, particularly sensitive personal data involving health, political, religious, or ethnic origin. The tool warns that editing may change PDF content or presentation, leaving users responsible for reviewing generated files. ZHAW states that it assumes no liability for generated PDFs.
