A brief googling reveals that there are various softwares that can do this, but as far as I know none that one can use on a Mac and is easily obtainable is free. A free and easy way to make not just djvu-to-pdf conversion but much more is to use DocsPal, which is a free web-based service.just upload your djvu file (it will probably recognise the file type automatically), choose the output format, and hit "convert." The file gets converted and a link to it appears. One drawback is that when one converts a djvu file to pdf, the file size gets significantly larger. I believe this is a general problem about these formats, not a shortcoming on DocsPal's part (but I might be mistaken.this problem is mentioned in many discussion threads online). One way of remedying this to reduce the file size using Word To Pdf Conversion (open the converted pdf file, select Document > Reduce File Size... and follow the instruction), but this does not usually make it as light as the original djvu file (this depends of course on the nature of the data embedded in the file).
How To Make Notable Papers In PDF The main part of making notable papers in PDF is to use the 'pdf-tool' (available at website). This is a browser-based program, that is easy to use, but needs an installation of the Adobe Acrobat Reader (available at ). It is easy to get. Download the appropriate installation file for your browser (for Firefox 1.0.1: ; for Netscape Navigator 3.x: ). Install the Acrobat Reader. Once Acrobat Reader is installed, launch the 'pdf-tool' by double-clicking on a 'PDF file' icon in the web browser toolbar. It will ask you how the file should be named, and whether the extension should be PDF_ etc. If you click yes (the default one), it will open the file in a new document viewer. Just click here, it only takes a second, and it's as light as the original file. If no file is opened, the 'pdf-tool' will automatically open that file.
