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.
Co właściwie powoduje uszkodzenie pliku PDF?▼
Typowe przyczyny to przerwanie pobierania lub przesyłania plików, awaria aplikacji podczas zapisywania, wadliwy nośnik pamięci lub oprogramowanie, które najpierw błędnie zapisało plik.
How does the repair process work?▼
Silnik przepisuje tabelę powiązań pliku i naprawia uszkodzone przesunięcia obiektów strumieniowych, zasadniczo odbudowując wewnętrzną mapę pliku PDF, dzięki czemu widzowie mogą ponownie zlokalizować i wyrenderować jego zawartość.
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.
What if the repaired file still won't open?▼
That usually means the damage goes deeper than structural corruption, such as missing raw page data, which unfortunately can't be reconstructed since it no longer exists in the file.
