Często zadawane pytania
What types of PDF damage can this tool fix?
Our tool can fix PDFs with corrupted headers, damaged cross-reference tables, incomplete downloads, and minor structural issues.
Will I lose any content when repairing a PDF?
The repair process attempts to recover all content. However, severely damaged files may have some unrecoverable content.
Why won't my PDF open?
PDFs may not open due to incomplete downloads, file transfer errors, storage corruption, or software compatibility issues.
Is repairing PDFs free?
Yes, our PDF repair tool is completely free with no registration required. Repair as many files as you need.
Should I keep my original file?
Yes, always keep your original file as a backup. The repair process creates a new file and does not modify your original.
How long does the repair process take?
Most repairs complete within seconds. Larger files or severely damaged documents may take longer to analyze and repair.
Can this fix password-protected PDFs?
This tool repairs structural damage, not password issues. For locked PDFs, use our Unlock PDF tool instead.
What if the repair fails?
Severely corrupted files may be beyond repair. Try the original source if available, or use professional data recovery software for critical documents.
Will the repaired PDF look the same?
Successfully repaired PDFs should look identical to the original. If content was unrecoverable, the repair report will indicate what was affected.
Can I repair PDFs from any source?
Yes, repair PDFs regardless of how they were created - scanned documents, exported files, downloaded documents, or files from any PDF software.
