Frequently asked questions about repair pdf
Will this always fix a broken PDF?
Not always — severe corruption in the underlying file data can be unrecoverable, but the repair process fixes many structural issues, like broken cross-reference tables.
What causes a PDF to become damaged in the first place?
Common causes include interrupted downloads, buggy export software, or a file that was truncated during transfer.
Is there a file size limit?
PDFs up to 100MB are supported, since repair runs on our server.
Are my files stored on your servers?
Files are processed for the repair and then deleted — they aren't kept or reused.
