Repair PDF
Repair damaged or corrupted PDF files.
What is Repair PDF File?
Repair corrupt or damaged PDF files by rebuilding object streams and cross-reference tables. Free, secure, and runs directly in your browser.
When should you use it?
This tool is useful when you need a smaller file, a more robust file, or text you can reuse in another application.
How Repair PDF File handles your file
The file is parsed and re-serialised with pdf-lib inside your browser. No upload.
Your device's own CPU does the work, so there is no upload wait and no server-side copy of your document to retain.
Good to know before you convert
- This is a re-save, not data recovery. If the parser cannot read the file, the tool cannot repair it.
- Files that are truncated, filled with null bytes, or missing whole objects cannot be recovered here.
- It cannot restore content that is not present in the file.
How to use Repair PDF File

Frequently Asked Questions
Can every corrupted PDF be repaired?
No. PdfPix re-parses and re-serialises the file, which resolves problems with a damaged cross-reference table or badly written object streams. If the file is truncated, missing objects, or full of null bytes, the parser will reject it and no repair is possible. A report tells you which files succeeded and which could not be read.
Does repairing a PDF delete pages?
No. If the file parses successfully, every page it contains is written to the rebuilt document.
Is this secure for business files?
Yes. Parsing and rebuilding run locally on your device and the file is never transmitted.
