PDF Attachment Embedder

How to Embed Files in a PDF

1. Add your PDF. Drop it in the first box, or click Choose PDF.
2. Add the files to embed. Drop them into the second box or click Browse Files. Any file type works and you can add several. A file with the same name as one already in the list is skipped.
3. Check the Files to Embed list. Use the x beside a file to take it out, or Clear All to empty the list.
4. Click Embed Files into PDF. The files are attached inside your browser tab.
5. Click Download PDF with Embedded Files. The copy is saved with _with_attachments added to the file name. Reset starts again.

Why Use This PDF Attachment Embedder

• Your file stays on your device. The PDF and the files you attach are handled by code running in your browser. Nothing is sent to a server.
• Pages stay as they were. The files are added to the PDF's attachment list, so text, fonts and layout are not redrawn or recompressed.
• Any file type, several at once. Images, Word files, spreadsheets, text files and more can travel inside one PDF.
• One file to send. A report and its source data stay together instead of arriving as separate downloads.

Good to know: attachments only show up in PDF viewers that support them, such as Adobe Acrobat and Foxit, and some browser or phone previews do not list them. The PDF grows by the size of everything you attach. The attached files are not encrypted, and anyone who has the PDF can pull them out, for example with Extract PDF Attachments. A PDF that needs a password to open cannot be used here until it goes through Unlock PDF.

FAQ

How do I attach a file to a PDF?

Add your PDF, add the files you want to embed, click Embed Files into PDF, and download the result. The files are stored inside the PDF itself.

Where will the attached files appear?

In the attachments panel of a PDF viewer that supports embedded files, such as Adobe Acrobat or Foxit Reader. They are not drawn on the pages.

Does embedding change the pages of my PDF?

No. The pages are not redrawn or compressed again, so text, fonts and layout stay exactly as they were. Only the attachment list changes.

Can I embed more than one file, and what types work?

Yes. Add as many files as you like, of any type. If two files share a name, only the first one is kept in the list.

Can I get the files back out later?

Yes. Anyone with the PDF can open the attachments panel in a viewer, or use the Extract PDF Attachments tool to download them all at once.

Is my PDF uploaded anywhere, and is there a size limit?

No, your PDF and your files stay on your device while they are processed in your browser. Your file size limit is shown on this page, and a free account raises it. The limit applies to each file you add.
