Why does it say my PDF has no attachments?

Most PDFs have no embedded attachments. Attachments are added deliberately (like attaching a spreadsheet to an invoice PDF). If your PDF shows content that looks like a file, it's probably an image, not an attachment — try Extract Images instead.

Q: What's the difference between attachments and images in a PDF?

Attachments are whole files (ZIPs, spreadsheets, PDFs, etc.) packaged inside the PDF as separate embedded objects — they don't appear on any page, they're just cargo. Images are visual content drawn on pages. This tool extracts the attachments.

Pull out files that are packaged inside your PDF as embedded attachments — spreadsheets, ZIPs, sub-documents, and anything else the author bundled in.

What are PDF attachments? Separate files (Excel sheets, Word docs, images, ZIPs) that are packaged inside the PDF as cargo — they don't appear on any page. Many PDFs have none; invoice templates and contract templates often do. If what you're seeing is drawn on a page, use Extract Images instead.

Frequently Asked Questions

What's the difference between an attachment and an image in a PDF?

Attachments are whole files (spreadsheets, ZIPs, sub-PDFs, etc.) packaged inside the PDF as separate embedded objects. They don't appear on any page — they're just cargo. Images are visual content drawn on pages. You can attach a Word document to a PDF and it never shows up in the visible pages. This tool extracts those attached files. For images, use Extract Images.

Why does my PDF show "no attachments"?

Most PDFs have no embedded attachments. Attachments are added deliberately by whoever created the PDF — like when someone bundles a spreadsheet with an invoice, or attaches source files to a report. If you were expecting a file and it's not showing up, the file might be:

An image drawn on a page — try Extract Images
A link to an external file (not embedded) — the URL would appear in text
Stored using a non-standard method this tool doesn't recognize

Can I preview attachments before downloading?

Yes — for many types. Text files (TXT, CSV, JSON, XML, MD, HTML) show inline. Images (PNG, JPG, GIF, WebP, SVG) render in the preview modal. Office documents, PDFs, and archives can't be previewed in-browser — for those you'll see an icon and can download directly.

What file types can be embedded as PDF attachments?

Anything. The PDF spec doesn't restrict attachment types. Common ones: XLSX, DOCX, CSV, ZIP, PNG, JPG, XML, sub-PDFs, and TXT. Some PDFs even embed executable files, which is why PDF attachments are a known malware vector — never open attachments from untrusted PDFs. This tool extracts them but doesn't run them.

Does the tool modify my PDF?

No. We only read the embedded files and hand you copies. Your original PDF is untouched and stays on your device.

Is my PDF uploaded to a server?

No. Everything runs in your browser using pdf.js. Your file never leaves your device.
