Frequently Asked Questions
What types of corruption can be repaired?
Structural corruption (bad cross-references, invalid object streams) and metadata errors. Severe binary corruption may require Pro server-side recovery.
Will all pages be recovered?
Recovery depends on the extent of damage. The repair log tells you exactly how many pages were recovered and what was preserved.
What causes PDF corruption?
Incomplete downloads, storage failure, interrupted saves, virus damage, or file system errors can all corrupt PDF files.
When should I use Pro repair?
When the free repair fails or shows "PDF too corrupted" — Pro uses a low-level binary scanner to extract content even from severely damaged files.
