Practical guide

What to know before you start

Extract attachments from a PDF online for free with KissPDF. This PDF attachment extractor finds document-level embedded files, page attachment annotations, Associated Files used by PDF/A-3 documents and files stored in PDF Portfolios. You can download one attached file or save selected PDF attachments as a ZIP.

Find files embedded inside a PDF

A PDF can contain original spreadsheets, XML invoice data, source documents, images, archives and other files that are separate from the visible pages. Some PDF readers hide these attachments or show only page-level paperclip annotations.

  • Document-level embedded files
  • Page attachment annotations
  • PDF/A-3 Associated Files
  • PDF Portfolio files

Review attachments before downloading

The results identify the stored filename, extension, MIME type, byte size, source PDF and attachment location. Page numbers, descriptions and Associated File relationships are shown when the PDF contains them.

  • Search by filename or description
  • Filter by file type and attachment source
  • Select only the files you need
  • Identify potentially unsafe file types

Download attached files from the PDF

Download an individual attached file with its original bytes, or select multiple PDF attachments and create a ZIP locally. Duplicate stored filenames receive distinct ZIP entries rather than overwriting one another.

  • Preserve original attachment bytes
  • Avoid filename collisions in ZIP files
  • Select several attachments from one PDF
  • No PDF upload

Attachments are different from images and links

This tool extracts files deliberately embedded as PDF attachments. Use an image extractor for artwork displayed on a page and a link extractor for web addresses and clickable annotations. Arbitrary PDF object streams are not presented as user attachments.

  • Use Extract Images for page artwork
  • Use Extract PDF Links for URLs
  • Attachments can contain unsafe files
  • Encrypted PDFs may require a password before inspection

Frequently asked questions

Clear answers based on how this tool actually works.

How do I extract attachments from a PDF?

Choose a PDF, review the detected embedded files, select the attachments you need, and download one file directly or multiple files in a ZIP.

What files can be attached to a PDF?

PDFs can embed many file types, including XML, CSV, spreadsheets, source documents, images and archives. The original creator decides which files are stored.

Can this extract attachments hidden by my PDF reader?

Yes. The scanner checks the document EmbeddedFiles name tree, page FileAttachment annotations and Associated Files rather than relying on the reader interface.

Does this support PDF Portfolios?

It detects embedded files referenced by a PDF Portfolio and labels them as Portfolio files. The Portfolio interface and other presentation metadata are not reproduced.

Can I extract invoice XML from a PDF/A-3 file?

Yes, when the XML is stored as an Associated File such as Factur-X or ZUGFeRD invoice data. The AF relationship is shown when present.

Are extracted attachments safe to open?

Not automatically. Attachments can contain executable code, macros or malicious documents. The tool warns about common active file types, but you should scan every untrusted file before opening it.

Why were no attachments found?

The PDF may contain only visible pages, images or links rather than embedded files. It may also be encrypted, damaged or structured in an unsupported way.

Are my PDF files uploaded?

No. Attachment discovery, file extraction and ZIP creation run locally in your browser.
