Frequently asked questions
- What kinds of PDF problems can this fix?
- It rebuilds a PDF’s internal structure, which fixes most issues caused by corrupted cross-reference tables or interrupted downloads — the common causes of a PDF that won’t open.
- Can every broken PDF be repaired?
- No. If the file’s content streams themselves are damaged beyond recovery, repair may fail or only partially restore the document.
- Does repairing change my PDF’s content?
- No. Repair only rewrites the file’s internal structure — pages, text, and images stay the same.
