Why can’t I see the attachments in my PDF reader?

Attachments usually live in the reader’s attachments sidebar (the paperclip in Acrobat, the attachments panel in Chrome or Edge), and phones and some readers don’t show them. Upload the file here to see every attachment, including icons placed on pages, and download them directly.

What kinds of files can I attach, and is there a size limit?

Any file type works—Excel, Word, images, ZIP archives, source code and more. There is no fixed limit, but attachments make the PDF correspondingly larger and processing is bound by browser memory, so keep each file under a few hundred MB.

Can a removed attachment be recovered from the file?

No. When saving, the tool rebuilds the attachment list and purges objects that are no longer referenced, so the attachment’s data is removed from the PDF rather than just its entry, and it can’t be extracted afterwards.

Are my files uploaded?

No. Reading, extracting, adding and removing attachments all happen in your browser with no network upload.

📎PDF Attachments - View, Extract, Add & Remove Embedded Files

A PDF can carry attachments just like an email: e-invoices embed XML data, tenders include price sheets, papers ship with raw data and drawings come with their source files. Yet many readers hide attachments deep in a side panel, and phones often don’t show them at all. This tool reads both document-level attachments (EmbeddedFiles) and attachment icons placed on pages (FileAttachment annotations), and lists each file’s name, type, size, description, modification date and page. Download any of them individually or grab them all as a ZIP. To attach files, pick anything—spreadsheets, images, archives, source code—add an optional description for each, and after saving, recipients can open them from the attachments panel in Acrobat, macOS Preview, Chrome or Edge; non-Latin file names display correctly. Attachments you mark for removal are purged from the file rather than merely unlinked, so the file gets smaller, while the pages stay exactly as they were. Everything runs locally in your browser and the file is never uploaded.
