NConvert 7.00
A batch image processor for the command line

NConvert is a command line tool for image batch processing.

The program can crop, resize and rotate images; tweak brightness, contrast and colour; apply sharpen or blur filters, add watermarks, convert images formats and more (80+ commands in total).

NConvert can work its magic on just about any file, too. The program reads more than 500 image formats, and can export to more than 70.

You will have to spend a little time learning how NConvert works, of course, but it's really not too difficult. Here's an example.

nconvert -out gif pic1.jpg

You can probably guess that this takes the file pic1.jpg and saves it in the GIF format.

Let's get more advanced.

nconvert -out gif -dither -colors 256 *.jpeg

Now we're converting a set of JPEG files to GIF, and defining how the colour palette will be created.

And now try this.

nconvert -out png -resize 200% 200% *.jpeg

There's no need to spell this out: the English-like syntax makes it all very obvious.

As you can see, there's no need to be put off by NConvert's command line origins. There is some work to be done in understanding its features, but you'll figure it out quickly enough, and there's more than enough batch processing power here to justify your efforts.
 

Verdict:

An extremely powerful batch image processing tool which is also fairly easy to use (by command line standards, anyway).

Windows 10 May 2019 Update ISO (build 1903)

Free Full Commercial Software

This is the latest version of Windows May 2019 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 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.

May 2019 Update brings a whole host of new features for Windows 10. See the Microsoft Blog for more information.

The Windows 10 ISO will give you build 1903 which is the May 2019 Update.
