CometPDF is a desktop PDF converter for Windows 10 and Windows 11. It converts Office files, images, emails, text files, and existing PDFs locally, and it also exports PDFs to images, text, Word, and PowerPoint.
Windows users often need fast conversion from Explorer, office folders, email archives, scan folders, and shared workstations. CometPDF is designed for that practical desktop workflow. You can use the installer for Start Menu, Desktop shortcut, uninstall support, and optional right-click conversion, or use the Portable ZIP when you do not want setup.
Because conversion happens locally, private files do not need to pass through online PDF services. This matters for contracts, quotes, financial spreadsheets, reports, scanned paperwork, and Outlook email files.
When Microsoft Office, Outlook, or LibreOffice are installed, CometPDF can use them for print-like conversion. This helps preserve formatting for Word documents, Excel sheets, PowerPoint slides, and emails.
Yes. CometPDF runs on Windows 10 and can convert supported files locally after installation or from the portable version.
Yes. CometPDF is also built for Windows 11 and supports the same local conversion workflows.
No. Conversion happens locally on your Windows computer. CometPDF does not send selected files to a server.
Office gives the most faithful results for Word, Excel, and PowerPoint. CometPDF also includes fallbacks for several formats when Office is unavailable.
