What types of PDF corruption can this tool fix?
PDFtiny repairs missing cross-reference tables (XREF), broken trailer dictionaries, truncated file streams, missing end-of-file (EOF) markers, and damaged stream headers.
Will my formatting and text be recovered?
All intact pages, text streams, font mappings, and embedded images that have not suffered fatal binary overwriting are reconstructed into a clean, newly serialized PDF.
