Câu hỏi thường gặp
What does PDF sanitization remove?expand_more
It strips hidden data including metadata, embedded scripts, attached files, comments, form fields, and revision history.
Why should I sanitize a PDF before sharing?expand_more
PDFs can contain hidden information like author names, edit history, GPS coordinates from photos, and embedded files that you may not want others to see.
Does sanitization change the visible content?expand_more
No. Only hidden and non-visible data is removed. The pages look exactly the same.
Is this the same as redaction?expand_more
No. Redaction removes visible content. Sanitization removes hidden metadata and embedded objects that are not visible on the page.
