Recover pages and content from damaged, corrupt, or truncated PDF files using a 5-strategy forensic repair engine — all running locally in your browser. Handles broken cross-reference tables, missing trailer dictionaries, absent %%EOF markers, corrupt stream lengths, and partially destroyed page trees.
To repair a corrupted PDF free, rebuild the internal structure that tells a reader where each page begins. On ihatepdf, upload the damaged file and five recovery strategies run in sequence — rebuilding broken cross-reference tables, restoring missing trailers and salvaging readable page objects. Free, no sign-up, and the repair runs entirely on your own device.
PDF files consist of objects (pages, images, fonts, streams) connected by a cross-reference (xref) table that acts as an index. When a file transfer is interrupted, storage fails mid-write, or a PDF generation process crashes, this index can become corrupted. PDF readers depend on the xref table to locate content — a broken index causes the reader to report the file as damaged. ihatepdf's repair engine uses multiple strategies to reconstruct this index by scanning the raw bytes of the file to locate recoverable content objects directly, bypassing the broken index entirely.
Broken cross-reference tables, truncated files, missing trailer dictionaries, absent %%EOF markers, corrupt stream lengths, and partially destroyed page trees.
No. All repair processing happens locally in your browser using WebAssembly. Your file never leaves your device.
If the damage is severe, only portions of the document may be recoverable. The tool repairs and recovers as much as the file structure allows — partial recovery is common for severely corrupted files.
Incomplete downloads, storage drive errors, interrupted file transfers, email attachment corruption, and failed PDF generation processes are the most common causes.
Often yes. ihatepdf's 5-strategy approach frequently recovers files that Adobe Acrobat and other viewers refuse to open.
