A few years ago, Mark12 pointed me at a Microsoft Powertoy, Image resizer.

Go to Microsoft website, and look for Powertoys. Install Image resizer.

A right click on said picture will include ‘Resize picture’ in the menu, and then you have the option to make it one of three sizes – all useful for web publishing.

Just a minor point about this tool. While it will reduce the file size because of the general reduction in physical dimensions, it doesn’t allow you to manipulate the resolution.

While in most cases that is highly desirable, if you have limited bandwidth larger filesizes can waste it unnecessarily.

So it is a good idea to reduce physical dimensions anyway, but reducing filesize while there is no noticeable difference in image quality, can help many of those people wanting to see your pictures.

For viewing on the Internet, it is a good idea to reduce the filesize, so that they cannot be enlarged or are of insufficient quality for publication in magazines, etc., without your express permission and access to the original image. This is a tactic I tend to use – which is why I often get castigated for poor image quality. I produce my images to be best viewed at the physical sizes I dictate, and they do not like being enlarged further (zoomed). When they are zoomed for intense inspection or publication, they tend to look awful.

Another point is that I do not know whether that tool allows you to trim (or “crop”) the image to give the most pleasing picture, or a picture that fits your particular needs.

I tend to crop my images so that they will completely fill my desktop at 1280×768 for my own use, and this means trimming the edges.

For showing on the Internet I will usually resize the image again, down to a maximum 744 pixels wide, maintaining the aspect ratio of 16:9.
