3-Heights PDF Analysis & Repair Tool
Zurich, Switzerland
What it is
3-Heights PDF Analysis & Repair Tool analyzes corrupt PDF documents and attempts to restore content that can still be recovered. It examines objects, page trees, and content streams, and can report error types, descriptions, page numbers, and event counts, including messages written to a log file. Repair options include restoring data streams, fonts, cross-reference tables, pages, and images; recovery can recreate a PDF from legible content that remains. The tool reads encrypted PDFs and can encrypt restored files with permission flags. Inputs include PDF 1.x, PDF 2.0, and PDF/A-1, PDF/A-2, and PDF/A-3; outputs include PDF 1.x or PDF 2.0. Pdftools documents Shell command-line and API variants, with Windows, Linux, and macOS support. Repair is local, and batch repair is supported. Pricing is on request, with a 30-day trial and no free plan. In the evaluation version, files can be analyzed but Save As is disabled, so repaired or recovered files cannot be saved or viewed without the full version. The vendor cautions that not every file can be repaired and some image compression methods cannot be recovered.
