3-Heights PDF Analysis & Repair Tool vs IntactFile

3-Heights PDF Analysis & Repair Tool analyzes damaged PDF documents and attempts to repair or recover their contents. It inspects objects, page trees, and content streams, then can report error types, codes, descriptions, page numbers, and event counts, with messages written to a log. Repair options include restoring data streams, fonts, cross-reference tables, pages, and images; recovery can rebuild a PDF from legible content that remains. It 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; the manuals cite ISO 32000-1 and ISO 32000-2 conformance. Pdftools documents Shell command-line and API variants, with Windows, Linux, and macOS support and local repair delivery. Batch repair is supported. The product is paid, with pricing on request and a 30-day trial. The evaluation version analyzes files but disables Save As, so repaired or recovered files cannot be saved or viewed without the full version. The vendor cautions that some files and image compression methods cannot be recovered.

IntactFile repairs corrupted videos, PDFs, ZIP, RAR and 7z archives, Office documents, JPG and PNG photos, and SQLite databases in a browser tab. Its repair engines rebuild damaged file structures around data that remains, such as indexes or headers, and run on the user's device; the maker says files are not uploaded. Diagnosis is free for each file, so users can see the problem before choosing a repair. Repairs are checked against format rules, and failed repairs are not charged. The Free plan allows 3 repairs per day, with video files up to 50 MB and documents, archives, and photos up to 10 MB. Paid choices include a single repair for €5.90 per once, credit packs, and annual plans: Pro is €4.92 per year and Business is €16.58 per year. Business adds CLI, SDK, and MCP server access; developer repairs require an active Business subscription and Node 22 or later. IntactFile cannot recover overwritten data, video never written to disk, or files containing only zero bytes.
