What are PDF Attachments?

PDF attachments are files embedded within a PDF document that can be opened, viewed, or extracted separately. Unlike regular PDF content, attachments are stored as separate files within the PDF container.

Common types of PDF attachments include:

  • Supporting Documents: Spreadsheets, Word files, or presentations referenced in the PDF
  • Source Files: Original images, drawings, or design files
  • Certificates: Digital certificates or signatures
  • Metadata Files: XML, JSON, or configuration files
  • Multi-media: Audio, video, or 3D model files
  • Archives: ZIP files containing related documents

  • Any hyperlinks pointing to removed attachments will be broken
  • Annotations referencing attachments may become invalid
  • The PDF file size will be reduced proportionally to removed attachments
  • Original PDF quality and layout are preserved

Yes, we offer separate tools for extracting attachments:

For workflow: First extract important attachments, then use this tool to clean the PDF.

No, there are no file size limits. Our tool processes files entirely in your browser, so the only limitation is your device's memory. However, for optimal performance:

  • Recommended: PDFs under 500MB for fast processing
  • Large files (1GB+): Processing may take longer depending on your device
  • Very complex PDFs: May require more system resources
  • For very large files, consider using Split PDF first

We prioritize your privacy and security through multiple measures:

  • Local Processing: All file processing happens in your browser using JavaScript
  • No Uploads: Your files never leave your device or reach our servers
  • No Tracking: We don't collect or store your PDF files or content
  • Open Source Libraries: We use trusted, open-source PDF libraries
  • Client-side Encryption: Your data stays encrypted on your device

For maximum security, use our PDF Sanitizer tool to remove all hidden data.
