Best 3 PDF Attachment Extractor Tools Compared
Manesh Jayawardhana

You’ve received a PDF that has other files embedded inside it — a spreadsheet, images, or additional documents bundled into the PDF’s attachment structure — and need to pull them out.
Embedded PDF attachments are different from regular images on a page; they’re separate files stored inside the PDF’s structure, only visible through a paperclip icon or attachment panel in a PDF reader. Extracting them properly needs a tool built specifically for that, not a general image extractor.
How to judge a PDF attachment extractor tool
Extracts actual embedded files, not page images. This distinction matters — an attachment extractor targets the PDF’s file attachment structure specifically, different from pulling images visible on the page.
Runs locally when possible. A PDF with sensitive embedded files shouldn’t need to be uploaded to a server just to list what’s inside it.
Offers ZIP download for multiple files. If a PDF has several attachments, downloading them all at once beats extracting one at a time.
No signup for a quick extraction. Pulling attachments out of a PDF is typically a one-off task.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| A.Tools | Fully client-side processing, ZIP download | Free, no signup | Extracts embedded attachments only, not visible page images |
| pdfup | No file size limits, browser-based | Free, no signup mentioned | No in-browser preview of attachments before download |
| Mapsoft | ISO 27001-certified server processing | Free tier with limits | Files processed on remote servers, not locally; registration needed for higher limits |
| PDF Attachment Extractor | Lists files with size, download individually | Free, no signup | No ZIP-all download for multiple attachments at once |
Facts checked August 2026; tools change their plans.
A.Tools
A.Tools processes files strictly on your device with 100% client-side processing, extracting all embedded attachments from one or more PDFs and bundling them into a downloadable ZIP archive.
It isn’t for someone hoping to also pull visible images from PDF pages — the tool is explicit that it extracts only embedded file attachments, not regular in-page images, and password-protected PDFs need unlocking first.
pdfup
pdfup runs entirely in your browser with no file size limits and files that never leave your device, downloading all extracted attachments as a single ZIP file.
It isn’t for someone who wants to preview attachments before downloading — the tool currently lists discovered attachments without offering an in-browser preview, so you extract first and check contents after.
Mapsoft
Mapsoft processes files on ISO 27001-certified UK servers with no software to install, offering a free tier alongside registration for higher daily limits and larger file sizes.
It isn’t for someone who wants confirmed local-only processing — files are uploaded to Mapsoft’s servers rather than processed in your browser, which is worth knowing if the PDF or its attachments are sensitive.
PDF Attachment Extractor
Our tool finds and lists files embedded inside a PDF’s attachment structure, showing each one with its size, ready to download — entirely in your browser.
A real limitation: it doesn’t offer a bundled ZIP-all download — for a PDF with many attachments, you’d download them individually rather than getting them all in one archive like A.Tools or pdfup provide.
Which one to pick
If you’re extracting one or two attachments and want a private, no-signup tool, use our PDF Attachment Extractor.
If your PDF has many attachments and you want them all in one ZIP, use A.Tools or pdfup.
If you don’t mind server-side processing and want higher limits through registration, use Mapsoft.
If privacy matters most, stick with the fully client-side tools — ours, A.Tools, or pdfup.

If the PDF containing the attachments is password-protected, you’ll need to unlock it first. Our PDF Password Remover strips owner-password restrictions from a PDF that already opens without a password, entirely in your browser.
Frequently asked questions
Is there a free PDF attachment extractor that doesn’t need an account?
Yes. Our PDF Attachment Extractor, A.Tools, and pdfup all work without requiring signup — Mapsoft’s free tier doesn’t require registration either, though registering unlocks higher limits.
What’s the difference between an embedded attachment and an image on a PDF page?
An embedded attachment is a separate file — like a spreadsheet, Word document, or standalone image — stored inside the PDF’s file structure and typically accessed through a paperclip icon in a PDF reader. An image on a page is rendered directly as part of that page’s visual content and requires a different kind of extraction tool entirely.
Why would a PDF have embedded attachments in the first place?
PDFs often embed supporting files to keep related documents together — a financial report might embed the underlying spreadsheet, or a legal filing might embed supporting exhibits, following the PDF specification’s file attachment feature designed specifically for bundling files this way.
Final thought
For pulling files out of a PDF’s attachment structure, prioritize a tool that processes locally, especially if the embedded content is sensitive — this is exactly the kind of extraction where keeping everything in your browser matters most.
