What is inside a PDF file, and what does repairing one do?

A PDF is a header naming its version, a body of numbered objects (pages, fonts, images, streams), a cross-reference table that records where each object starts, and a trailer pointing at the catalogue and the metadata. Metadata lives in the Info dictionary (title, author, dates, producer) and, since PDF 1.4, in an XMP stream; fonts are embedded whole, subsetted or only referenced by name. A viewer that cannot find an object walks the file to rebuild the cross-reference table — repair does the same and writes the rebuilt table, which fixes most "damaged file" errors without touching the pages.

Frequently asked questions about PDF Information

What does "restrictions only" mean next to encryption?

The file opens without a password but is encrypted with an owner password that limits printing, copying or editing. PDF Permissions shows and changes the flags.

Can I inspect several files at once?

Yes. Drop them together; each file gets its own block of facts and a comparison table is added.

Why does the page count differ from my reader?

It should not — the count comes from the page tree. If a damaged file shows a different number, run PDF Validator and Repair PDF.

Is my PDF uploaded to a server?

No. The file is opened and processed by your browser with WebAssembly and JavaScript; nothing is sent to Mutqan Soft or anyone else. Close the tab and the file is gone. Downloading the result needs a free account — no subscription, no payment.

Can I use it on a password-protected PDF?

Yes, if you know the password: the file list asks for it once and every operation then works on the decrypted pages. The output is saved without a password unless you protect it again.

Technical notes

Facts come from three readers: pdf-lib for the object tree (pages, catalog, trailer, fonts, images, encryption dictionary), the byte stream for the header version, the linearisation marker, cross-reference streams and the startxref markers counted as incremental updates, and the XMP packet for PDF/A and PDF/X claims — reported as claims, never as verified conformance.
