Downloading PorDiBle 3.4 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. This free Mac application was originally produced by Loghound.
We recommend checking the downloaded files with any free antivirus. The application is included in Productivity Tools. The most popular version among the application users is 3.4. Pordible3_4.dmg is the default file name to indicate the PorDiBle installer.
From the developer:
PorDiBle is an application to convert between text documents and Palm DOC files. Text files can be dropped onto PorDiBle and will be converted to a compressed .pdb file which can be read by any one of a myriad of Palm ebook readers, such as SmartDoc, TealDoc and iSilo. Conversely, dropping a DOC .pdb onto PorDiBle will convert back to a text file. PorDiBle can also convert HTML to DOC, albeit by stripping all tags in the process.
You may want to check out more Mac applications, such as Voluminous, PDF to EPUB or CHM Reader Ultimate, which might be related to PorDiBle.
