Optimise PDF/ DJVU's for mobile devices

K2pdfopt is a powerful tool which can optimise PDF and DJVU documents for reading on mobile devices (e-readers, tablets, smartphones).

This isn't a matter of cutting resolution, or applying other basic tricks. K2pdfopt makes far more intelligent use of your reading space by trimming white space, cutting and cropping documents, reflowing text, then reassembling everything to fit the smaller viewing area.

OCR abilities (via Tesseract) means the program can even work with scanned pages. It's able to identify text, reflow it, and then add an OCR layer to the finished document. Not only will this mean it'll be easier to read the pages on a small screen, but your document will also become searchable.

While this sounds complicated, the program can be surprisingly easy to use. Drag and drop multiple documents onto the program, choose your target device (or set page width, height and dpi manually), and use the Preview button to inspect the results. If you're happy, click "Convert All Files" and wait as the mobile-friendly versions are produced.

If the default settings don't deliver what you need, life can be a little more complicated, as there are a lot of options to consider. Should the "Conversion Mode" be "default", "copy", "trim", "fitwidth", "fitpage", "2-column", "crop"...? You can find out just by trying a new setting and previewing the results, but it can take some time to find out what works best.

Don't let this put you off trying the program, though. We found k2pdfopt usually delivered great results, and as it's open source there are no adware or other hassles to worry about: it's completely safe to install and use.

Version 2.33a (Version History):
    - Fixed MS Windows GUI bug where preview page controls were missing.


Smart, easy to use and very configurable, K2pdfopt is an excellent tool for anyone who regularly needs to view desktop-oriented PDFs on a small screen.

WhatsApp Messenger 2.12.11

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.11 brings:

• Links that you share or receive will now include a rich preview. When sending a link, you have the option to not include a rich preview.
• Additional 3D Touch features: You can now quickly Peek and Pop chats.
• Redesigned Settings tab. 
• You can now view all your starred messages across all your chats in Settings — Starred Messages.
