Attach Files to PDF
Embed any file (document, image, zip) inside your PDF as an attachment. Attached files appear in the attachments panel when you open the PDF. Everything happens in your browser — no file is uploaded anywhere.
No PDF selected yet.
You can select more than one file. Each file max 50 MB.
How to use
- Select your PDF file.
- Select the files you want to attach inside the PDF (documents, images, zip).
- Click "Attach and Download PDF" and download the new PDF — the attachments appear in the attachments panel of Adobe Reader and similar tools.
Tips
- After downloading, open the attachments panel (paperclip icon) in your PDF reader to confirm every file was embedded.
- Each attachment is limited to 50 MB — very large attachments can make the PDF slow to open on phones.
- Use the Remove button to drop an unwanted file from the list before attaching, instead of starting over.
- Give attachments clear file names first — those names appear inside the PDF’s attachments panel.
