Recover page order, rotation, dimensions, resources, and inherited metadata.
No. 03
Unreadable streams.
Repair or bypass corrupt compression blocks while preserving visible content.
No. 04
Missing fonts.
Substitute broken font maps so text can render without turning every page blank.
No. 05
Bad metadata.
Remove invalid trailer entries and rewrite the catalog into a stable structure.
No. 06
Partial downloads.
Extract readable objects from incomplete files and save the recoverable pages.
Repair process
Recovery happens in passes.
The page explains repair as a calm diagnostic sequence, not a generic utility panel.
i.
Scan the object map.
Read every reachable object, detect broken offsets, and build a fresh inventory from the raw file body.
ii.
Rebuild the document spine.
Recreate catalog, page tree, outlines, resources, fonts, and page dimensions in a valid order.
iii.
Recover page content.
Decode streams, preserve images and text, and skip only the sections that cannot be safely read.
iv.
Write a clean copy.
Export a stable PDF with repaired references, normalized metadata, and readable page structure.

Q & A
Questions before repairing.
Focused answers for the most important PDF Repair product page.
Q.01What kinds of PDFs can be repaired?+
Files with broken references, damaged catalogs, invalid trailers, missing page-tree links, corrupt streams, bad metadata, and partial downloads are the main candidates.
Q.02Can every corrupt PDF be fixed?+
No repair tool can recover bytes that are completely missing, but a structural repair pass can often recover readable pages from files that standard readers reject.
Q.03Why is Repair the lead page?+
Because the site is called PDF Repair first. The editor and converter are supporting document tools, while repair is the core promise.
PDF Repair is now the front desk.
This page gives the repair product its own dedicated identity inside the new site.
