Some PDFs contain embedded files that are separate from the visible pages. These PDF attachments can include spreadsheets, source documents, XML files, images, archives, or older drafts. This tool lets you inspect the attachment list and remove embedded files from a PDF when they are unnecessary, outdated, sensitive, or too large to share.
Upload a PDF that may contain attachments. The tool reads the embedded file list in your browser and displays available attachment details. Select the attachments you want to remove, then save a new PDF. If the document has no embedded files, the tool will let you know so you can use another cleanup tool instead.
Edit PDF attachments before emailing contracts, submitting compliance documents, publishing reports, or archiving client files. Removing unused embedded files can reduce file size, prevent accidental disclosure, and make a PDF easier to review. It is especially helpful when a PDF was exported from office software or document management systems.
The PDF is processed locally with no upload. The output is a cleaned copy of the PDF with selected attachments removed. Page text, images, and layout are not intentionally changed by this attachment editor, and your original source file remains on your device exactly as it was.
