- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Redacting email content or sensitive data inside a PDF portfolio.
- Observed behavior
- Standard redaction or document sanitization processes might inadvertently remove metadata or file attachments if specific cleanup options are selected.
Always create a backup copy of your original PDF portfolio before applying redactions, as redaction is a permanent action that cannot be undone once saved.
Apply Redactions to Visible Content Only
Selectively redact text and images without triggering document sanitization features that remove attachments.
When redacting a PDF, many PDF editors prompt you to sanitize the document to remove hidden data. Sanitization strips metadata, bookmarks, and importantly, file attachments. To keep your attachments, you must bypass the sanitization step.
Launch your PDF editor and open the PDF portfolio containing the documents you need to redact.
Navigate to the 'Protect' or 'Security' tab and choose the 'Redact' tool from the ribbon menu.
Carefully highlight only the visible text or images (such as phone numbers, personal emails, or confidential paragraphs) that need to be hidden.
Click 'Apply Redactions'. When prompted to sanitize the document or remove hidden information, ensure you uncheck any options related to removing metadata, bookmarks, or file attachments, or simply skip the sanitization prompt.
Save the document as a new file. Open the newly saved file to verify that the sensitive information is blacked out while the attachments remain accessible in the attachment pane.

Frequently Asked Questions
Why did my attachments disappear after redacting a PDF?
This usually happens if you accepted a prompt to 'sanitize' the document or remove hidden information during the redaction process. Sanitization automatically strips metadata, bookmarks, and file attachments to ensure no hidden sensitive data is leaked.
Can I undo a redaction if I accidentally removed an attachment?
If you haven't saved and closed the document yet, you can use the Undo function (Ctrl+Z). However, once the document is saved and the redaction is fully applied, it is permanent. This is why keeping a backup before editing is crucial.
Is redaction different from drawing a black box over text?
Yes. Drawing a black shape only covers the text visually; the underlying text can still be highlighted, copied, or read by screen readers. Proper redaction permanently removes the text data from the file's code.
