3-Heights PDF Analysis & Repair Tool examines damaged PDF documents, reports problems, and attempts to restore their contents. It can inspect objects, page trees, and content streams, with reports that include error type, description, page number, and event count. Repair options cover data streams, fonts, cross-reference tables, pages, and images; recovery can rebuild a PDF from content that remains legible. It reads encrypted PDFs and can encrypt restored files with permission flags. Supported inputs include PDF 1.x, PDF 2.0, and PDF/A-1, PDF/A-2, and PDF/A-3; listed outputs are PDF 1.x or PDF 2.0. The vendor documents Shell command-line and API variants, with Windows, Linux, and macOS support. The product is paid, with pricing on request and a 30-day trial. The evaluation version can analyze files, but Save As is disabled, so it cannot save or view repaired or recovered PDFs without the full version. The vendor does not guarantee recovery of every file, and some image compression methods cannot be recovered.
