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?▼
Vanliga orsaker inkluderar en avbruten nedladdning eller filöverföring, en kraschad applikation under lagring, felaktiga lagringsmedia eller programvara som skrev filen felaktigt från början.
Hur fungerar reparationsprocessen?▼
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.
Kommer reparation att ändra hur mitt dokument ser ut?▼
Målet är att återställa det ursprungliga utseendet så nära som möjligt - reparation fixar den underliggande strukturen snarare än att ändra din text, bilder eller layout.
Vad händer om den reparerade filen fortfarande inte öppnas?▼
Det innebär vanligtvis att skadan går djupare än strukturell korruption, såsom saknade råa siddata, som tyvärr inte kan rekonstrueras eftersom den inte längre finns i filen.
