ORPALIS PDF Reducer Free
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 3.0.32 (see changelog for more)?

- Dramatically improved the PDF/MRC generator.
- Battery of minor bug fixes.


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.

Windows 10 October 2018 Update (build 1809)

Free Full Commercial Software

This is the latest version of Windows October 2018 Update. it's a media creation tool that can be used to upgrade an existing installation of Windows or create installation media for another PC. Just make your choice after launching the tool and it'll do the rest.

What was new in Windows 10, when it was released? The OS brought back the Start Menu, though with a Windows 8 twist: live tiles keep you up-to-date with the latest news while also providing an easy way to launch apps. (Don't worry if you prefer the Start Screen, it's still there and you can boot into it if you prefer.)

Apps now work much more like regular desktop programs. They have minimise, maximise, restore and close buttons, and can be resized (to a degree) and organised however you like.

If you've still lost track of a program in the mass of open windows, a new Task Spaces feature can help. Click its taskbar button and you'll see thumbnails for everything running now, a little like OS X's Mission Control - just click something to switch to it.

Better still, Task Spaces also supports virtual desktops. Add extra desktops as required and it'll display thumbnails of each one, making it easy to identify whatever you're after and switch to it.

There's also smarter snapping, new customisation options, and even a bunch of experimental additions to the command prompt.

Fall Creators Update brings a whole host of new features for Windows 10. See the Microsoft Blog for more information.

The Windows 10 ISO here will give you build 1809 which is the October 2018 Update.
