Windows 10: How to Reduce Image File Size JPG, PNG Without Changing Dimensions on Windows 10?

Hi everyone,I'm looking for a way to resize, specifically reduce the file size of images in JPG and PNG formats, while keeping the same dimensions. For example, I want to convert multiple 5 MB files to 800 KB files on Windows 10.Are there any built-in applications in Windows that can do this? If not, can someone recommend a privacy-focused app that doesn't require a login?I'm open to paid options as long as they are reasonably priced and prioritize user privacy.Thanks in advance!

Why does saving an image without changing anything in Paint reduce size drastically?

Someone recently suggested that I use MS Paint in my Win 7 machine to reduce file size without reducing image size. I gave it a try. I opened a 137mb tif file that was exported from LR 5 with the Prophoto RGB color profile into MS Paint and immediately saved it as a tif without changing anything to the file. The resulting tif file was only 14.8 mb! The image size was identical to the 137 mb file. Paint did not change the color profile. I opened both files in PS CS6 side by side, extremely zoomed in on areas of the image and could not tell the difference by looking at them on the monitor. There was no banding as usually seen in compressed jpgs. No apparent loss of detail at all. I have been looking online for an explanation for HOW Paint does this and found this relatively old thread. No real answers to be found here but at least the topic is addressed. I can understand compressing a jpg to reduce file size, but not a tif file. My plan is to make extreme crops from both files and have them printed to see what I get. This should be the real test for the MS Paint file size reduction. BTW, I have over 35 years of professional photography experience and look at images very critically.

 

Desktop Background Slideshow - Change fit based on image dimensions

Hello,

Windows 10 includes a lot of personalization settings where users can change their desktop background, colors, lock screen background, and the like. About your query, the fitting of your slideshow images depends on the size or dimension of each picture.
Even though having a standard slideshow size is not attainable, we suggest using an image editor or application to modify the dimensions of your graphics. This way, you'd be able to achieve a standard size setting on all of your slideshow pictures.

windows explorer image dimensions - change to height x width

Open a folder of images in Windows Explorer. List by Details. Open the Dimensions column. This gives you the size of the images by width and height. You can now list the images by width, from wide to narrow, but you cannot search by height, that is, tall to small. I wish to list by height.
