Don't be so quick to judge this app!
I acquired it via another give away site recently and I can assure you this is a highly refined application that works flawlessly, with lots of attention to detail.
(The kind of quality one comes to expect from most German developers).
BTW; 'TK', it performs BOTH file re-sizing and image dimension changes.

Note: My OS is Windows 7 -- the right click utility that Microsoft provided for WIn XP would not work with my current OS, so, I located a clone for that utility that was written for Win 7 users and yes it works pretty good.
HOWEVER, today's offering blows it out of the water.

Note: I have no affiliation with this company. I am just a satisfied user that didn't like seeing the misinformed comments posted today about this offering. I would like to see more quality offerings here, that are of comparable quality. We don't need more converters!

So give this app a chance. THEN come back here and post an informed comment.

Also, re: the asking price... I rarely purchase software, but I would consider paying for this app. I am impressed by quality and attention to detail and responsiveness of software developers. It's a rarity today and when I see it I like to applaud it.

My suggestion to the devs would be to be the 1st, or among the 1st to include Google's Guetzli in their app -- the 1st apps to do so will stand out from the crowd, & I'd imagine it would be a good selling point.

arstechnica[.]com/information-technology/2017/03/google-jpeg-guetzli-encoder-file-size/

""Google has developed and open-sourced a new JPEG algorithm that reduces file size by about 35 percent—or alternatively, image quality can be significantly improved while keeping file size constant. Importantly, and unlike some of its other efforts in image compression (WebP, WebM), Google's new JPEGs are completely compatible with existing browsers, devices, photo editing apps, and the JPEG standard."

If it helps at all...
The jpeg format is similar to mp3, in that it looks for parts in an image that can be deleted without compromising that image *too* much, the same way that mp3 throws out audio data you hopefully won't miss. The jpeg quality level set determines how much is thrown away, & thus how small the file is. Re--encoding a jpeg image [saving an edited jpeg as a jpeg] you lose data twice, which is where the Google code could come in.

Images also have two measurements, pixels & dpi or ppi. A web page normally has images at the standard monitor 96 dpi, same as what you'd probably send/receive via email. When you use a scanner or printer you're often dealing with 300 or 600 dpi. If you were to print a 96 dpi image, either the printer &/or its software will upscale the image, lowering quality, or it will convert it to a higher dpi, keeping the original quality, but shrinking the dimensions of the image.

What's the advantage over any other image viewer with batch functionality (e.g. FastStone Image Viewer)?
