How can I compress image size under 100kb without losing quality

Hello everyone,

My new website is currently under development, but many of the original JPEG images are over 2MB each. For better page loading speed, the goal is to reduce the file size to under 100KB per image while keeping them as sharp and professional-looking as possible.

There are many options available, such as resizing the dimensions, lowering JPEG quality, converting to newer formats like WebP, or using AI image compression tools. As a beginner, it is difficult to know which method provides the best balance between image quality and file size.

How can I compress image size under 100KB without noticeable quality loss? Are there any recommended Windows tools or batch-processing solutions that work well for website optimization?

Thank you!
