Question 1

Why did Repair PDF not give me a download?

Accepted Answer

The file is already healthy. There is nothing to rebuild. That is expected.

Question 2

How does PDF repair work?

Accepted Answer

It copies pages into a new document. A broken xref or trailer often disappears. Missing pages cannot be invented.

Question 3

Does repair overwrite the damaged PDF?

Accepted Answer

No. You only get a new file when a rebuild is needed.

Question 4

Can repair open a PDF I do not have the password for?

Accepted Answer

No. Unlock first if a user password blocks the open.

Question 5

Will repair restore a file that shows zero pages?

Accepted Answer

Only if pages can still be read. A truncated download may be gone.

Question 6

Does repair upload the PDF?

Accepted Answer

No. The copy happens in the browser.

Question 7

Should I repair before converting to PDF/A?

Accepted Answer

Yes if the converter errors. A clean page copy is a better source. Still confirm veraPDF yourself.

Question 8

Does repair change page quality?

Accepted Answer

No. Pages are copied, not rasterized.

Question 9

Is repair the same as flatten?

Accepted Answer

No. Flatten locks fields. Repair rebuilds structure.

Question 10

Can I repair a PDF that only fails in one reader?

Accepted Answer

Try it. A new document often satisfies the strict reader. Keep the original if the friendly reader was already fine.

Question 11

Will repair remove owner restrictions?

Accepted Answer

Not as its job. Use Unlock if print or copy is blocked and the file otherwise opens.
