CometPDF 1.1.0
Download CometPDF for Windows.
Download CometPDF as a Windows installer or a Portable ZIP. Both versions convert files locally on Windows, support no-upload PDF conversion, and include PDF export tools for images, text, Word, and PowerPoint.
Windows may warn you before installing
CometPDF is not yet code-signed, so Windows SmartScreen or Chrome may show an "unknown publisher" warning when you download or run the installer. This is expected for a new unsigned Windows app. To proceed: click More info -> Run anyway. If you prefer to skip this entirely, use the Portable ZIP - no installation, no warning.
Installer
Recommended for everyday use. The installer can add Desktop and Start Menu shortcuts, uninstall support, and optional right-click conversion from Windows File Explorer.
