3-Heights PDF Analysis & Repair Tool examines damaged PDF documents and attempts to restore their content. It can inspect objects, page trees and content streams, then report error types, descriptions, page numbers and event counts, including in a log file. Repair options include restoring data streams, fonts, cross-reference tables, pages and images; recovery can rebuild a PDF from content that remains legible. The tool reads encrypted PDFs and can apply permission flags when encrypting restored files. Supported inputs include PDF 1.x, PDF 2.0 and PDF/A-1, PDF/A-2 and PDF/A-3; outputs are PDF 1.x or PDF 2.0. The vendor cites ISO 32000-1 and ISO 32000-2 conformance. Shell command-line and API variants are documented for checking and fixing files, with Windows, Linux and macOS platforms listed. Repair is local, and batch repair is supported. The paid product has pricing on request and a 30-day trial. Evaluation permits analysis but disables Save As. The vendor cautions that some PDFs and image compression methods cannot be recovered.
