CometPDF

Top comment
Hi Product Hunt, I built CometPDF because many PDF converters require users to upload private files to a server. That is not ideal for contracts, invoices, spreadsheets, internal documents, or email archives. CometPDF runs locally on Windows. It supports Office files, images, Outlook MSG/EML emails, text/data files, batch conversion, optional merge, and PDF export tools like PDF to image, PDF to text, PDF to Word, and PDF to PowerPoint. The first public version is free. It is not code-signed yet, so Windows may show an unknown publisher warning, but checksums and security notes are published on the site. I would love feedback from people who handle private documents or need offline PDF workflows on Windows.
