PRIVACY BY DESIGN

Local Processing: Your PDF Stays in Your Browser

The PDF is processed in the current browser tab. The page downloads its PDF and ZIP libraries from third-party CDNs, but does not send your selected PDF to our conversion servers.

🛡️

Temporary Browser Memory

The PDF is read by PDF.js in your browser. The selected document and extracted attachment data are kept in browser memory while you use the tool.

🧹

No PDF Server Upload

The extractor uses temporary in-memory buffers. Use the Change Document button to clear the current results; closing the tab also releases the page's memory.

⚖️

Privacy-Aware Workflow

Your PDF contents are not uploaded by this tool. As with any browser-based service, keep your browser updated and review the privacy policies of third-party scripts loaded by the page.

How to Find and Download PDF Attachments

Learn where PDF attachments are stored, which files can be previewed, and what to check when an attachment is missing.

1

How Does PDF Attachment Extraction Work?

Reading document-level embedded files and page-level file attachments

PDF attachments are stored as file specifications in the document structure or as file-attachment annotations on individual pages. This tool reads those structures and makes supported attachment data available for download.

  • ✓ Document-Level Files: PDF portfolios and embedded-file name trees can contain XML, CSV, spreadsheets and other documents.
  • ✓ Page-Level Files: A page can contain a file-attachment annotation with a downloadable embedded file.
  • ✓ Read-Only Extraction: The source PDF is inspected but not modified by this tool.
2

Extract Attachments Tool vs Basic Reader Annotation: Which Should You Choose?

Understanding key workflow differences to select the optimal solution

Choosing the right workflow ensures higher document fidelity, reduced file size, and complete security compliance:

Feature & Function Extract Attachments Tool Basic Reader Annotation
Security & Permanence Find and download files attached to the PDF A standard PDF reader may show attachments but may not offer convenient bulk export
Privacy Standard The selected PDF is inspected locally in the browser Often syncs sensitive contracts to commercial cloud accounts
Compliance Compatibility Reads embedded file structures supported by the PDF parsing libraries Attachment visibility depends on how the PDF was created
3

Which PDF Attachments Can Be Extracted?

Common embedded file formats and PDF structures

PDF attachments can be stored in more than one place. This tool checks document-level embedded files and file-attachment annotations on individual pages:

  • ✓ Document-Level Files: PDF portfolios and embedded-file name trees can contain XML invoices, spreadsheets and other supporting documents.
  • ✓ Page-Level Attachments: PDF pages can include file-attachment annotations that store separate downloadable files.
  • ✓ Original File: The extraction process reads the PDF and does not rewrite or modify the source document.
4

How Are Attachment Names and Files Handled?

Understanding safe filenames, duplicate files and local downloads

PDF files can store attachments in document-level name trees or as file-attachment annotations on individual pages:

  • ✓ Original PDF: The source document is not rewritten or changed during extraction.
  • ✓ Safe File Names: Unsafe path segments are sanitized and different attachments with the same name receive a unique suffix.
  • ✓ Preview Options: Common text and raster image files can be previewed; other formats can be downloaded and opened separately.
5

Technical Limitations & Practical Best Practices

Important compatibility and browser-memory considerations

To maintain maximum security and document reliability:

  • ✓ Password-Protected PDFs: Unlock the PDF with a password you are authorized to use, then save an accessible copy before extracting attachments.
  • ✓ PDF Compatibility: Some damaged, encrypted or unusual PDF structures may prevent the parser from reading attachments.
  • ✓ Browser Memory: Large PDFs and many attachments use memory. This tool limits PDF size, attachment count and extracted data for stability.

DIAGNOSTICS & QUICK FIXES

Common Issues & Troubleshooting Fixes

Encountering an unexpected hurdle with your document? Here are the most effective solutions and diagnostics.

🔒

“The PDF Opens but No Attachments Are Found”

Symptoms: The PDF loads, but the attachment list is empty

✓ Instant Solution

Not every PDF contains embedded files. Check whether the source is a PDF portfolio or includes file-attachment annotations. Visible links or icons do not always mean a file is embedded.

📦

“A Specific Attachment Is Missing”

Symptoms: A PDF reader shows an attachment that is not listed here

✓ Instant Solution

Some PDFs use unusual or nested embedded-file structures that a browser parser may not expose. Try opening the PDF in a desktop reader and saving or exporting its attachments.

⚠️

“The PDF Cannot Be Opened”

Symptoms: The browser reports an invalid or unreadable PDF

✓ Instant Solution

Download the PDF again and confirm it opens in a trusted PDF reader. If the file is damaged or incomplete, repair or re-export it before trying the extractor.

📐

“The PDF Is Password-Protected”

Symptoms: The PDF parser requests a password or cannot read the document

✓ Instant Solution

Unlock the PDF using a password you are authorized to use, then save an accessible copy and scan it again.

📝

“A Preview Is Not Available”

Symptoms: The attachment is listed but cannot be previewed here

✓ Instant Solution

The tool previews common text and raster image files. Download other formats and open them with a suitable application. SVG preview is disabled for safety.

🔁

“The Browser Becomes Slow During Scanning”

Symptoms: The tab becomes slow while scanning a large PDF or many attachments

✓ Instant Solution

This tool accepts PDFs up to 100 MB and limits extracted data to help protect browser memory. If a PDF is unusually large, try a smaller copy or use a desktop PDF utility.

QUESTIONS & ANSWERS

Frequently Asked Questions

Answers to common questions about unpacking PDF portfolios, embedded files, and formats.

Q What kinds of embedded attachments can this tool unpack from a PDF?

Our extractor scans the PDF's internal /EmbeddedFiles dictionary and extracts any embedded file type, including Excel spreadsheets (.xlsx, .csv), Word documents (.docx), raw photos (.jpg, .png), vector graphics (.svg), ZIP archives, and source code.

Q Can I preview and download individual attachments or download all as a ZIP?

Yes. Preview supported text and image files, download any listed attachment individually, or bundle the detected files into a ZIP archive. Very large ZIP exports may be limited by available browser memory.

Q Does extracting attachments modify or damage the original PDF document?

No. The tool reads the PDF and does not modify the original file. Your original PDF remains unchanged on your device.

Q Are the extracted files byte-for-byte identical to the originals?

The tool extracts the decoded attachment data exposed by the PDF structure without intentionally editing the attachment contents. If exact forensic byte-for-byte preservation is essential, verify the extracted file with a trusted checksum workflow.

Q Are my confidential legal exhibits or attached datasets sent to any server?

The selected PDF is read and inspected in your browser; the file contents are not uploaded to our conversion servers. The page does load its PDF and ZIP libraries from third-party CDNs.
