Let's dive in and take control of your PDF security.
Method 1: Remove PDF Metadata with Adobe Acrobat Pro
Best for: Professionals needing thorough, compliant metadata removal
While Adobe Acrobat Pro offers a straightforward process for removing PDF metadata, this feature is only available in the paid version. A quick guide is provided below:
Why Use Acrobat Pro?
- Removes 100+ hidden fields (author, edits, comments, attachments)
- Batch processing is available via Action Wizard
- GDPR/HIPAA compliant for legal/medical docs
Step-by-Step Guide
1. Open: Launch Acrobat Pro and open your PDF (File > Open).
2. Properties: Go to File > Properties (Ctrl+D).
3. Basic Info: In "Description," clear or change Author, Title, Keywords, and Subject.
4. Advanced Removal: Click "Additional Metadata," then the "Advanced" tab, and select "Remove All." Confirm.
5. Extreme Security (Optional): For highly confidential files, use Tools > Redact > Remove Hidden Information and check all boxes.
6. Save Securely: Choose File > Save As to create a clean version. Always keep the original.
Method 2: Windows Built-in Limitations for PDF Metadata Removal
Important Note: Native Windows tools CAN NOT reliably remove PDF metadata
The Reality Check (What Doesn't Work):
File Explorer Attempt: Right-clicking a PDF, going to "Properties" > "Details," and clicking "Remove Properties and Personal Info" will not effectively erase the PDF's internal metadata. You might see changes in File Explorer, but the data remains inside the document.
The "Print to PDF" Trick
1. Open and Print: Open your PDF in a web browser like Edge or Chrome and press Ctrl+P (or Cmd+P on Mac, though this section primarily addresses Windows limitations).
2. Choose Printer: Select "Microsoft Print to PDF" as your printer.
3. Save: Save the new PDF file. This process strips away the original metadata. 
macOS
PDF metadata removal is not possible in macOS. Users are limited to viewing and adding some metadata, accessible by right-clicking the document and selecting 'Get Info.'
Method 3: Remove Metadata via Online Tools
Best for: Quick fixes on non-sensitive documents
Step-by-Step Guide
1. Upload: Go to Sejda PDF metadata online editor and drag-and-drop your PDF or click "Choose File" to upload it.
2. Choose an Option: Select an option which are "Remove all metadata" and "Change metadata".
3. Save and Check: Save your changes and then reopen the Properties to ensure the metadata fields are blank.
