Repair PDF guide
How to repair a damaged PDF
Fylento attempts to rebuild damaged PDF structure directly in your browser and creates a new PDF copy when the file contains recoverable data.
Add the damaged PDF
Select one PDF from your device. Repair PDF can still attempt recovery when the file is too damaged for its page count to be read safely beforehand.
Run the repair
Fylento analyzes the PDF structure and attempts to rebuild a readable document from the recoverable PDF data.
Download the rebuilt copy
If repair succeeds, download a new PDF with “-repaired” added to the original file name.
What PDF repair can and cannot do
PDF repair is most useful when the file still contains its document data but parts of the internal PDF structure are damaged or inconsistent.
Rebuild recoverable PDF structure
Fylento attempts to parse and rebuild the file into a fresh PDF when enough valid PDF data remains.
Create a clean output copy
The result is written as a new PDF rather than overwriting the original damaged file.
Missing content cannot be recreated
If pages, images, text, or other PDF data are completely missing or destroyed, a repair tool cannot reconstruct information that is no longer present in the file.
Some PDFs will remain unrecoverable
Severely damaged files, encrypted PDFs, or files that do not contain recoverable PDF data may still fail to repair.
Repair can be attempted even when page count cannot be read
A damaged PDF may fail normal validation before repair. For this tool, Fylento still enforces the local file-size limit but allows the repair attempt to continue when the page count cannot be determined safely.
File-size limits still apply
The selected PDF must still fit within your plan's local maximum file size.
Unreadable does not always mean unrecoverable
A PDF that cannot be read normally may still contain enough valid structure for the repair engine to create a usable copy.
Repair PDFs privately in your browser
The repair engine runs on your device. The damaged PDF does not need to be uploaded to a remote repair server.
Local PDF processing
Fylento loads its PDF repair toolkit in the browser and performs the recovery attempt locally.
Original file is left untouched
Successful repair produces a separate downloadable copy, so you can keep the original file for reference.
When PDF repair is worth trying
Repair PDF FAQ
Can Fylento repair every corrupted PDF?
No. Repair succeeds only when enough recoverable PDF data remains. Severely damaged, encrypted, or incomplete files may not be repairable.
Can repair restore deleted or missing pages?
No. Repair can rebuild existing recoverable structure, but it cannot recreate page content that is completely absent from the file.
What happens to my original PDF?
Nothing. Fylento creates a separate repaired copy and leaves the original file unchanged.
Can I try repairing a PDF that Fylento cannot count the pages of?
Yes. Repair PDF specifically allows an unreadable PDF to proceed to the recovery attempt when the page count cannot be determined safely, while still enforcing the local file-size limit.
Does Fylento upload the damaged PDF?
No. The current Repair PDF tool performs the recovery attempt locally in your browser.
