Our newest app, 4K Image Compressor, can optimize not just single files one after another—in fact, it’s a perfect tool if you want to compress a bunch of JPG, PNG, WEBP, HEIC, and PDF files at one go and save a few hours to do something you really enjoy. In this post, we’ll tell you everything you should know about the batch optimization in 4K Image Compressor.

How to Compress Multiple Files at Once

First of all, prepare the files you’d like to compress and put them in one place on a desktop or in one folder for easier access. Then, take the following steps:

1. Install 4K Image Compressor on your Windows PC, Mac, or a Ubuntu computer and launch it.

2. Choose the input format of the files you want to compress. The app supports JPG, PNG, WEBP, HEIC, and PDF.

3. Choose the Optimization settings. Depending on the chosen format, various optimization options will be available.

4. Select several files you want to compress to drag and drop them to 4K Image Compressor.

5. Wait a few seconds (literally!), and 4K Image Compression will reduce sizes of all the files you’ve just uploaded.

6. Preview the results by tapping the Show Comparison button: Simply right-click on the image preview to compare the original and compressed images in three distinct modes: side-by-side, split view, and slider comparison.

7. Open the compressed files on your computer by clicking on them.

That’s it! Long minutes of daunting one-by-one compression are saved!
