3-Heights PDF Analysis & Repair Tool vs Restore.Media

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.

Restore.Media repairs damaged or unplayable video and audio files through a browser. It scans media tracks and recreates missing or damaged headers, metadata and indexes. Listed formats include MP4, MOV, M4A, M4V, MXF, 3GP, INSV, RSV and MP3. The service says its processing is adapted to particular cameras and supports hundreds of camera models, encoders and recording applications. Files up to 128GB can be uploaded, and users can view a full-length low-resolution preview before paying for an original-quality download. Automatic recovery costs $4.99, paid once per file; the price varies with file size, and there is no subscription. Manual recovery by engineers is also available, with a negotiable quote based on order volume and complexity. The service says uploads are processed automatically and are not viewed unless manual recovery is requested. Users can delete tasks and files; inactive tasks and files are automatically deleted after 7 days. Restore.Media does not repair distortions, freezes or artifacts in video that otherwise plays, and recovery may fail if source video data is corrupted.
