Frequently Asked Questions
What types of PDF corruption can be repaired?
The PDF Repair tool can fix common issues such as missing cross-reference tables, incorrect object offsets, and truncated files. Severely corrupted files where the content itself is damaged may not be fully recoverable.
How does PDF Compare work?
PDF Compare renders both documents and highlights visual differences between matching pages. Added content, removed content, and changed text are shown in distinct colours so you can quickly review what changed.
Can I compare PDFs with different page counts?
Yes. The comparison tool matches pages by position (page 1 vs page 1, page 2 vs page 2) and flags pages that exist in one document but not the other.
Will repaired PDFs be identical to the originals?
The repair tool rebuilds the PDF structure around the content that is still readable. In most cases the output is visually identical to the original, but metadata or embedded elements that were in the corrupted sections may be lost.
