We’re thrilled to announce the release of a completely new product—4K Image Compressor, the tool that helps you easily resize PNG, JPEG, and WEBP files with high-quality output.

In this post, we’ll tell you about what the new app can do, how to get started, and how it can be useful.

What 4K Image Compressor Can Do

Spot the difference :) No quality loss after the compression.

Compress Pictures & Photos to the Size You Need

With 4K Image Compressor, you can resize files quickly and without quality loss to easily share images on social media or save your device’s storage space.

If you need images for your website, the app comes in handy as well since if you choose compressed yet high-quality images, you'll improve your website’s loading time and secure higher search engine rankings.

Reduce the Image Size

4K Image Compressor allows you to set a custom size to fit your specific needs and reduce PNG, JPEG, and WEBP images by a percentage or by a certain amount of megabytes or kilobytes.

Resize Images in Batch

Another great feature is the ability to minimise the size of multiple images from MB to KB in seconds. Such bulk compression of pictures might save a significant amount of your time.

Compress Images in All Popular Formats

You can upload images in various lossy and lossless formats and download the compressed files in JPEG, PNG, and WEBP.

More features, such as image editing, batch compression to a particular size, cloud storage, preview and post-view, image watermarking, and PDF support are coming soon.

How to Get Started with 4K Image Compressor

Here’s the definitive step-by-step guide on how to use the application.

Download and launch 4K Image Compressor on your desktop computer. It’s compatible with Windows, macOS, and Ubuntu devices.

After the launch, you’ll see the main window of the app.

On the main window, add an image by pressing the plus icon at the top left. Alternatively, you can add images by clicking the big blue Compress button (which can be seen only if there are no compressed images yet), following the File -> Compress Images path, drag and drop, and Ctrl+V hotkey.

If you’re a paid user, you can add multiple images in a batch.

On this page, you can also set the required compression format. HEIF and PDF are not yet supported but will be added in upcoming releases.

And set the optimisation settings.

Wait for the compressed image to appear on the main window.

On the left, these are the input format and size. On the right, there’s the output format and size. The % indication means how much space you’ve saved compressing this image.

Where Can I Find the Compressed Images?

Pictures you’ve compressed with the application are saved in the default folder that you can access from the main window next to the compressed image.

If there are no images on the main screen yet or you want to change the default folder, head over to Preferences -> General -> Output Folder.

Note that the output file has the same name as the input file!

Which Formats Can I Compress Images To?

All in all, these are the following:

Same as Input means that the output format will be the same as the input format. So, if you upload a PNG image, the output format will be PNG as long as the ‘same as Input’ is chosen.

PNG / JPEG / WebP ensures that the output format will comply with the one you choose in the settings. Note that the image might also be converted! 4K Image Compressor isn't a compressor alone, but a converter, too.

Which Optimisation Settings Are There in 4K Image Compressor?

Auto.

The auto settings can be changed in Preferences -> Auto Optimisation.

From here, you can also enable the lossy compression and change the quality parameter for each format. Note that the quality parameter digit doesn’t let you unmistakably count the size of the output file. Besides, this parameter works differently for each format.

Lossless.

This optimisation parameter isn’t supported for JPEG files.

File Size.

This setting always gives you lossy compression. Next to the settings, you can adjust the desired size in bytes (B), kilobytes (KB), megabytes (MB), and percentage (% by which you want to make the image smaller), so if you want to reduce the 100KB file by 25%, choose 25%, and the output size will be 75KB, which is 25% smaller than the input file size.
