What Repair PDF does — and what it doesn’t
Rebuild readable PDFs and normalise their structure.
Repair can rebuild structure; it can’t invent missing content
A readable but structurally awkward PDF may be normalised by rebuilding it. If bytes, images or fonts are genuinely missing from the source, no local repair step can recreate information that isn’t there.
The edge case to remember with Repair PDF: PDFs can carry fonts, forms, layers, annotations and unusual page boxes that don't always behave like a flat image. Repair cannot recover data that is genuinely missing or corrupted beyond recognition.
Where Repair PDF fits cleanly
Use it when you need to try to recover PDFs with minor structural issues; it also fits when you need to normalise files created by unusual exporters. If the job asks for more than that, split the workflow rather than making one tool do two different things.
The point where Repair PDF stops helping
Use compression, editing or conversion tools when the PDF already opens normally and the problem is size, content or format rather than structure.
