Most image viewing programs have a built-in feature to help you change the size of images. Here are our Increase Image size in kb online free favorite image resizing tools for Windows. We’ve picked out a built-in option, a couple of third party apps, and even a browser-based tool.
Maybe you need to upload a smaller version of a photograph to Facebook (they do it automatically and badly when you upload anyway) or another social site. Maybe you want to include an image that isn’t so ridiculously oversized in an email. Or maybe you want just the right size image to include in a blog post or Word document. Whatever your reason, it’s not hard at all to resize an image. We’ve rounded up our favorite tools for doing it in Windows, whether you need to resize just one image or a whole batch at once.
A Quick Note on Resizing Images
The quality of a resized image really depends on the original image you’re resizing. Photographs tend to do best, at least when you’re reducing the size of an image, because they have lots of detail to begin with. High resolution photos are more open to blowing up to larger sizes, but even they have their limits—blow up a photograph too much and things start to get grainy.
Here’s an example of a resized photograph. The original image was 2200×1938 pixels, and we cropped it down to a mere 400×352. The image is crisp, and the details still present.
If you’re working with a screenshot that you took on your PC or mobile device—or any image that contains text—resizing tends not to work terribly well. Here’s an example of a screenshot taken at 1920×1040 pixels, and then resized down to 600×317 to fit on our site.
It’s okay if you just want to show the broad look of things, but not so much for detail. That’s why we prefer cropping screenshots to resizing them for our articles, like with the image below.
So, with that out of the way, let’s move onto the Windows tools you can use to resize your images.
Built-In: Use Paint To Resize Your Photos
Paint has been a staple of Windows since version 1.0 in 1985. Chances are you’ve used it before. Paint opens most common file types (BMP, PNG, JPG, TIFF, and GIF) and offers a very straightforward approach to resizing images.
In Paint, open your image by opening up the File menu, and then clicking the “Open” command.
Find and select the image you want to resize, and then click the “Open” button.
On the Home tab of the Paint toolbar, click the “Resize” button.
Paint gives you the option of resizing by percentage or by pixels. It uses percentage by default, and that’s fine for rough resizing. If you need something specific, you’ll need to switch over to using pixels. When you type a horizontal or vertical value, Paint automatically creates the other value for you to maintain the original image’s dimensions.
Select the percentage you want, or the desired dimensions, and then click the “OK” button.
If you only need to resize one image at a time and don’t want to install any third-party apps, Paint is a pretty decent resizing solution.
Note: As of 2017, Paint has been added to the deprecated list of apps no longer being developed by Microsoft. Instead, they are replacing Paint with Paint 3D. Paint is likely not going away for a while, though, and you’ll still be able to download it from the Windows Store.
