PDF2MOBI

PDF2MOBI is a very small and portable Windows application whose only purpose is to turn PDF documents into Mobipocket ebook files (MOBI format), thus making them compatible with devices such as MobiPocket Reader.
It does not come bundled with complicated features or configuration parameters, making it accessible to all types of users, including those inexperienced with PDF conversion utilities.
Since installation is not a requirement, you can put the EXE file in any directory on the hard disk and just click it to run.
There is also the possibility of saving MobiPocket Reader to a pen drive or other mass storage device, in order to run it on any PC easily and without previous installations.
An important aspect to take into account is that MobiPocket Reader does not create new registry entries or additional files without asking the user's consent, thus leaving no traces behind after its elimination.
The straightforward interface consists of a small window, where you can use the file browser to locate the PDF document you want to convert. The drag-and-drop method is not featured. Batch processing is not supported either, so you can work with only one item at a time.
As specified in this panel, two files are created after conversion: in HTML and MOBI format, respectively. Images cannot be used.
MobiPocket Reader runs on a pretty low amount of CPU and memory, so it has minimal impact on system performance. However, it popped up an error during our tests, which prevented some PDF files from turning into MOBI. Users are advised to look for a more stable application concerning PDF-to-MOBI conversions.
