Frequently Asked Questions
Will this fix every broken PDF?▼
It fixes most common structural damage, like a file that was interrupted mid-download or has a broken cross-reference table. If the file is severely truncated or its raw data is scrambled beyond that, full recovery may not be possible.
What actually causes a PDF to become corrupted?▼
Common causes include an interrupted download or file transfer, a crashed application while saving, faulty storage media, or software that wrote the file incorrectly in the first place.
How does the repair process work?▼
The engine rewrites the file's cross-reference table and fixes broken stream object offsets, essentially rebuilding the PDF's internal map so viewers can locate and render its content again.
Will repairing change how my document looks?▼
The goal is to restore the original appearance as closely as possible — repair fixes the underlying structure rather than altering your text, images, or layout.
Bagaimana jika fail yang dibaiki masih tidak dapat dibuka?▼
Ini biasanya bermakna kerosakan menjadi lebih mendalam daripada rasuah struktur, seperti kehilangan data halaman mentah, yang malangnya tidak boleh dibina semula kerana ia tidak lagi wujud dalam fail.
