Caesium is a free, simple image optimization software made by SaeraSoft for bloggers, photographers, businesses, webmasters, or casual users at storing, sending and sharing images.

Features:

Caesium gives you the ability to set the quality for webp/webp images before compression, or change the image format from webp (lowest size format), webp, BMP, or the same format as the input image.

There’s also a resize feature. It allows you to change the width, height, an option to keep aspect ratio and an option not to enlarge the images. You can also choose either from absolute or percentage.

Pros:

• Free.
• Simple interface.
• Runs on Windows and Mac.
• An option to keep metadata.
• An online compressor and a downloadable one.

Cons:
