Shrink your PDF file sizes

ORPALIS PDF Reducer is an interesting tool which optimises PDFs to cut their file size by up to 80%.

This isn't another tool which just cuts document resolution, either: PDF Reducer uses multiple tricks to do its work.

If the file contains scanned documents then it may mix colour and black and white pages, for instance. PDF Reducer detects the black and white images and encodes them as plain B&W, often with dramatic savings.

The program examines individual PDF objects, removing any which aren't used, and resampling unnecessarily high resolution images.

PDF Reducer also applies multiple compression techniques on some images, reducing file size without losing any quality.

There's support for linearization, too, which enables large documents to be viewable by web users before the complete file has downloaded.

All this is easy enough to set up, and at a minimum you could just point PDF Reducer at your source files, give it an output folder, and click a button.

Please note, though, ORPALIS PDF Reducer has a very annoying nag screen. If you're launching a big batch processing task then it'll start as normal, but after every 5 documents, all work is stopped, the nag screen appears, and there will be a countdown of several seconds (up to 12 in our tests) until you clear it. After that, you get a few more seconds of processing before it's paused again.

The finished documents can be significantly reduced in size, and there are no watermarks or other catches. But if you're going to be regularly batch processing large numbers of PDFs, the constant interruptions are going to be a major hassle.

The Professional Edition removes the nag screen, adds a command line interface, multi-threading support, and accepts almost 100 input formats, too (it becomes a super-efficient "anything > PDF" converter). It's yours for $199.

What's new in 3.0.23 (see changelog for more)?

- Battery of minor bug fixes
- Improved performances in term of speed and compression ratio.


ORPALIS PDF Reducer is a well-designed product which really can dramatically reduce the size of many PDFs. The nag screen makes it annoying to use when batch processing large numbers of files (25+), but it's still better than the watermarks or resolution limits of other programs.

WhatsApp Messenger 2.18.81

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.

What's New in Version 2.18.81

- You can now use Siri to send messages to WhatsApp groups.
- Group voice and video calls are now available. When you're in a call, tap the “Add Participant” icon. Group calls support up to 4 total participants.
