PDFpen

It provides a native macOS environment for creating and modifying PDF documents. Users can open existing PDFs, edit text and images, rearrange pages, and add annotations such as comments, highlights, and drawing marks. The application also supports filling out interactive forms and saving changes without requiring external converters.

The tool is aimed at anyone who works with PDFs on a Mac—students, office workers, and professionals who need to adjust documents, insert signatures, or combine multiple files into a single PDF. Its interface follows macOS conventions, allowing users to perform edits with familiar keyboard shortcuts and mouse actions.

Because it is released as a stable product, it is intended for regular, reliable use rather than experimental or beta‑stage features. The software runs exclusively on macOS, integrating with the operating system
