PDF files se metadata hatayein
PDF me metadata ki do layer hoti hain: Info dictionary (title, author, creation date, producer app) aur XMP packets — sambhavatah har page par. PDF metadata se 'anonymous' documents decades se de-anonymize hote aaye hain. PureClear dono layers ko page-by-page sweep karta hai.

Sawal, jawab sahit
PureClear har page kyun sweep karta hai?
PDF me XMP metadata har page par ho sakta hai, sirf document level par nahi. Document-level clean page-level metadata miss kar sakta hai — isliye PureClear saare pages check karta hai.
Kya mera PDF dikhne me badlega?
Nahi. Content streams ko kabhi chhua nahi jaata — sirf metadata dictionaries clear hoti hain. Text, images aur layout bilkul same rehte hain.
Kya yeh blacked-out text ko redact karta hai?
Nahi — aur yeh zaroori hai samajhna. Metadata strip karna redaction nahi hai: agar aapne text ko kaale boxes se dhaka hai bina hataye, to text ab bhi content layer me hai. Uske liye proper redaction tool use karo.
