Compress Image Size With Different Compression Level for Each Image

Compressing image size offers a number of benefits, especially for those who often upload their images to the web. The lower size an image has, the faster it is to load. For users who wants to save their disk spaces, compressing images is also an alternative solution that can be put into consideration. Caesium is one of the many free image compression programs out there. The main advantage of using this app compared to other similar programs is that you can compress as many images as you want with each having its own compression level.

Look at the screenshot above. You can see that I have set different quality settings for some of the images.

Here you are some of the Caesium features and some tips of using it

• You can add pictures individually or add a folder. If you want to include the subfolders into the scan, enable the option first in the Preferences window.
• The preview function lets you compare between the original and compressed image.
• To set a different compression level to an image, select the image, drag the quality slider to set the quality, and click the “Set Quality” button to apply the change. You can also select multiple images to set a quality to several images at once.



• Depending on the image size, it is possible that the compressed image has a larger size. To avoid getting any result like this, go to the Preferences window and select “Skip if the output size is greater than the original” to enable the option.
• The image size in the preview is set to fit to window by default, which is very small. Consider choosing the “Original Size” in the Preferences window so that you can have a better view when comparing the images in the preview panel.
• Still in the Preferences window, you can also remove the check mark on the “Keep EXIF information while compressing” to get a lower size for each compressed image.
• Remove the check mark on the “Check for updates at startup” to avoid the program checking for updates everytime it is launched.



• If you run the compression instantly without previewing first, you won’t be able to compare between the output and original after the compression is finished. Unless you want to compress a huge amount of images, it is suggested to preview each image before compression to find out how it will look like later.
• The supported images for compression include JPG, JPEG, PNG, BMP and WMF files and you can save them either in JPG, BMP or PNG.
• The preview panel can be dragged for a larger view.
• After compression, the program displays a report containing information on the number of errors, skipped images and compressed images, the time it needs to compress all of the images, and the saved disk space.



• You can save the list of the images to be processed at a later time if you haven’t finished adding the images. This is pretty useful especially when you add images from different folders but having not enough time in the middle of the process.
• If you want to save the output in the same folder where the originals are stored, use the custom suffix before starting the compression to name the files.
