Download for Claude DesktopAbout 13 MB. For Mac and Windows. Needs Google Chrome or Microsoft Edge.

How to install

Install Claude Desktop. Download the file above and open it. Claude Desktop shows what the extension can do. Confirm to install it.

What you can ask

Name the file and the task. For example: “Make report.pdf in my Downloads smaller than 1 MB” or “Merge invoice.pdf and receipt.pdf on my Desktop.” The result is saved next to your file. Your original stays unchanged.

Tools you can use

Most tools work, including Compress PDF, Merge PDF, Split PDF, Protect PDF, PDF to Word, Annotate PDF, Edit PDF and Redact PDF. Sign PDF, Organize PDF, Compare PDFs, PDF Overlay, Scan to PDF, PDF Workflow and PDF Reader work on this website only. Text recognition (OCR) is not included.

What Claude asks you first

Claude asks before it runs a tool. Some steps need your own answer, such as confirming that you may unlock a PDF or that a redaction is final. Claude must ask you before it confirms them.

What stays on your computer

Your PDF is never sent anywhere. The extension runs the tools in a hidden Chrome or Edge window on your computer. Claude sees what you type and what the tools report, such as file names and messages. For Edit PDF, Claude also sees the text you ask it to change.

Updates and warnings

The extension does not update itself. When we improve the tools, download it again. Claude Desktop may show a warning because this extension is not listed in its directory.
