Adobe Create PDF is a web service that allows users to convert files with a maximum file size of 100MB to PDF, combine multiple files into a single PDF file, and convert PDF files to the Word (DOCX) or Excel (XLSX) formats. One free conversion is available to anyone logging in with their Adobe ID. Unlimited PDF file conversions are available with a paid subscription. Users can create a PDF file by uploading their file via a web browser, printing to a virtual printer (a download for their local PC), or selecting a file to convert from the Share pane in Adobe Reader X.
