Files remain in their original format and there is no need to unzip them before using them. It also allows you to customize the balance between quality and compression ratio, which is a very useful feature for images.

You can use NXPowerLite Desktop for free but if you need to have access to more sophisticated features to accomplish your work – you can buy the full version.
FILEminimizer – Scan specific folders or the entire hard drive
FILEminimizer Pictures is a simple and free application for image compression. The first thing that you’ll notice when you start this application is its simple and a bit outdated interface.
In order to compress your images, you just need to find them and add them to the application.
There’s a useful feature available that will scan certain folders, or even an entire hard drive and allow you to add pictures to the FILEminimizer Pictures tool.
Regarding the configuration, you can choose between three presets or you can set the custom level of compression. You can also choose an output directory or add suffixes or prefixes to compressed images.
This is a simple tool for image compression, and its biggest flaw is an outdated user interface. Speaking of the user interface, there’s no preview window, so you won’t see any changes until you compress your images.
FILEminimizer Pictures is a simple tool, and if its outdated user interface isn’t a problem for you, be sure to try it out.
Caesium Image Compressor – Free image compression software download
Caesium Image Compressor is an open-source image compressor. In order to compress your images, you simply need to add them to the application and set the desired options.
If you want, you can also add entire folders directly to Caesium Image Compressor. The user interface is split into three columns.
The first column is Compression Options and from there you can set the image quality. You can also choose between several formats such as JPG, PNG, and BMP.
Unfortunately, you can’t change image quality for PNG or BMP images. If you want, you can use the same quality for all images on your list.
The next column is in charge of resizing. From there you can set an absolute or relatively new size for your images.
If you want, you can also apply the same settings for all images on the list. Of course, there’s an option available that will let you keep your aspect ratio.
The last column is in charge of the output folder. You can set a different output folder for your compressed images, or you can keep them in the same folder.
If you want, you can also add a suffix to your images so you can easily distinguish them.
Even though this is a simple application, it has its share of flaws. In order to see a new size, compression ratio, and quality of the image, you’ll have to check the list of files.
We have to mention that the list can be sometimes sluggish, so it can take about five or more seconds for data to update. You can force data to update by clicking the Set Quality button if you don’t want to wait.
Even though there’s a side-by-side comparison, the compressed image preview won’t update automatically unless you click the Preview button, which is also a flaw in our opinion.
Caesium Image Compressor is a great application for image compression. This tool is simple to use and it has all the basic options available.
Unfortunately, some users might be turned away by some of its minor flaws. We have to mention that a portable version is also available, so you can run this app without installing it on your PC.
JPEGmini – Lossless image compression software
JPEGmini is a lossless image compressor, and according to its developers, this tool can reduce the file size of your pictures up to 5 times.
All your pictures will keep their original format and they will suffer almost no quality loss during compression.
We have to mention that this tool is rather simple, and all that you have to do is to add your images to it, and it will automatically compress them.
Keep in mind that by default JPEGmini overwrites the original images with compressed ones, so be sure to change your settings first.
Speaking of settings, we have to say that JPEGmini offers few settings. There’s no quality slider, so you’ll have to rely on the application algorithm to figure out the best quality settings for your images.
The application does a good job, so you’ll hardly notice any visual changes after compressing your images. In addition to compression, you can resize the images or set a specific output folder for compressed images.
JPEGmini is a simple application that allows you to resize your JPEG images without any configuration. This application will be perfect for basic users, especially with its visually appealing and simple user interface.
If you want more advanced options, you’ll have to use a different application. We also have to mention that JPEGmini is available as a free trial.
The free version allows you to compress up to 20 images per day, which should be enough for basic users.
FileOptimizer – Nifty photo compressor app for Windows 10
FileOptimizer is another free tool that can optimize your images. This application was originally designed for compressing all sorts of files, but you can also use it to compress your images.
FileOptimizer comes with a humble user interface, and in order to optimize your images, you just need to add them to the tool. Regarding compression, you can choose between several compression levels.
We have to warn you that by default this application moves original files to Recycle Bin and replaces them with compressed files. Of course, you can turn this option off if you want.
There’s no preview window or any advanced settings, which can be a flaw for some users. During the compression process, you’ll see the original size and optimized size of each file, which is rather useful.
This tool isn’t optimized for image compression, but if you want to compress your images and other files, this tool can be useful.
This application is available in a portable format, so you can run it on your PC without installing it.
Mass Image Compressor – Preview & file size information displayed
Mass Image Compressor is another free image compression software. Unlike other tools on our list, this one is designed to compress entire image folders.
In fact, you can’t add single images to this app, so you’ll have to organize images that you want to compress.
After selecting the desired folder, you should be able to change options such as image quality and image size.
You can choose between fixed width or set a percent-based width for your images. In addition to changing quality and size, you can also change the image format to JPEG or PNG or keep the same file format.
Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
Click here to download and start repairing.
You can also save compressed images to a specific directory, or you can overwrite the original images. Mass Image Compressor comes with a preview window that lets you see a sample image.
This is a useful feature, but unfortunately, there’s no way to toggle between different images, which is a flaw in our opinion. In addition to the image preview, there’s also information regarding the file size next to it.
This is a simple application for image compression, but unfortunately, this tool isn’t designed for single images.
You can’t add individual images to the application, and you can’t see previews or compression results for individual images which can be a problem for some users.
Overall, if you have multiple photos that you want to compress, this tool will be perfect for it.
PNGGauntlet – PNG-focused photo compression software
PNGGauntlet is an image compression software optimized for PNG files. The application allows you to convert other file formats such as JPG, GIF, TIFF, and BMP to PNG.
Unfortunately, you won’t be able to save images to JPG or any other format except PNG. This tool uses PNGOUT, OptiPNG, and DelfOpt to compress your images, and you can configure each of them individually.
Just like with many other tools on our list, you can choose an output directory or overwrite original files. Unfortunately, there’s no preview window available, which is another flaw in this application.
PNGGauntlet is a great application if you want to optimize PNG files, but if you have your images stored in any other file format, we suggest that you try a different app.
RIOT – Color quantization & different encoding options
RIOT stands for Radical Image Optimizer, and this is another free image compression tool. This tool is lightweight, but it offers advanced features, so it can be used by both basic and advanced users alike.
Regarding file support, this tool allows you to optimize JPEG, GIF, and PNG images. The tool comes with two panes that will show you the original and optimized image.
RIOT comes with an in-place compare feature that will temporarily replace the original image in the preview pane with the compressed one so you can examine the changes in a single pane.
The tool allows you to change the image quality of JPEG images, but it also allows you to choose different encoding options.
If you want, you can also perform image adjustments and change brightness, contrast, gamma, and other settings.
You can also rotate or flip your image if you need to. There’s a resample option available, and you can use it to resize the image using 6 different resampling filters.
During resampling, you can set the desired width or height in pixels or percents and choose to keep the aspect ratio if you want.
Regarding PNG images, you can change the color reduction profile or choose the number of colors manually. In addition, you can change the compression, and color quantization, or use external optimizers.
As for GIF images, you can choose color reduction presets or reduce the number of colors manually. You can also add images to RIOT directly from the clipboard, which can be rather useful.
RIOT also comes with a useful option that lets you compress the image to the desired size in KB. There’s also support for batch optimization, so you can quickly edit and compress multiple images at the same time.
One thing that we don’t like about batch optimization is the lack of ability to set the desired quality. There’s also no preview window for batch optimization, which can be a problem for some users.
Despite those minor flaws, this is still one of the best image compression tools on our list.
