Remove PDF Attachments (Free, Private, No Upload)
PDF files can contain hidden embedded attachments—additional files tucked inside the PDF structure that may include spreadsheets, images, source documents, or even executable scripts. While attachments can serve legitimate purposes like including supporting documentation, they can also pose security risks, bloat file sizes, or contain outdated information you'd rather not share. This tool empowers you to audit and remove those embedded files without sending anything to an external server, giving you complete control over your document's contents. Simply load your PDF, review the list of detected attachments with their filenames and sizes, and selectively delete anything you don't need or want to share. All processing happens entirely in your browser, ensuring that confidential records, proprietary information, and sensitive business documents stay strictly under your control. This privacy-first approach is critical when handling legal contracts with embedded exhibits, financial reports with attached spreadsheets, or technical specifications with bundled CAD files. The tool proves especially useful when cleaning invoices before sharing them with accountants, stripping potentially risky JavaScript from downloaded PDFs, removing unnecessary bulk from documents to reduce file size, or preparing files for public distribution by ensuring no confidential attachments remain hidden inside. Corporate users often need to sanitize PDFs before sending them outside the organization, and students may want to remove draft attachments before submitting final papers. Unlike some PDF editors that require expensive subscriptions or complicated installations, this browser-based solution works immediately without downloads, works on any operating system, and processes files as quickly as your device allows. Whether you're concerned about security, privacy, file size optimization, or simply maintaining clean document hygiene, this attachment removal tool provides a straightforward solution that respects your data sovereignty.

FAQ
Is it private?
Yes, this tool operates entirely within your browser using client-side JavaScript, which means your PDF files and their attachments are never uploaded to any external server or stored in the cloud. This architecture ensures complete confidentiality for documents containing sensitive embedded files like financial statements, proprietary data, or personal identification documents.
Can I delete attachments individually?
Yes, the tool displays a detailed list of all embedded attachments, allowing you to selectively choose which items to remove while preserving others that you want to keep. This granular control is valuable when you need to remove only specific confidential files while retaining necessary supporting documentation within the PDF.
Does it change the main PDF content?
No, the removal process only deletes the embedded file attachments from the PDF's internal structure without touching the visible page content, text, images, or formatting. Your document's pages, layout, fonts, and visual elements all remain completely unchanged, ensuring the PDF looks and reads exactly as it did before.
How many attachments can I remove?
You can remove as many embedded attachments as exist within your PDF, limited only by your device's available memory during processing. Most PDFs contain just a handful of attachments, but the tool can handle documents with dozens of embedded files if necessary.
Does it work on mobile?
Yes, the attachment removal tool functions in modern mobile browsers on both iOS and Android devices, making it convenient to audit and clean PDFs on smartphones or tablets. The interface adapts to touch input, though the desktop experience offers easier navigation when working with PDFs containing many attachments.
