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

JPEG Imager - This is a lightweight, free tool specifically designed to compress JPEG and BMP files using a unique "smart filtration" algorithm. It aims to reduce file size without the usual quality degradation. It is free, supports batch processing, and features a simple slider for controlling the quality/compression balance.

The interface is super simple—it's basically two windows side by side:

• Left side: Your original image
• Right side: The compressed result (updated in real-time as you tweak settings)

You control the compression using a slider at the bottom. The catch? Higher compression = smaller file = more noticeable quality loss. So you slide it around until the right window still looks good but the file size (which it shows you) has dropped significantly.

Besides helping you compress image size without losing quality, it's got some other handy tricks:

• Batch processing: Compress a whole folder of images at once
• Format support: JPEG, PNG, GIF, and BMP
• Basic edits: Crop, rotate, adjust brightness/contrast, add watermarks
• Drag and drop: Just drag your image into the window—super easy

If you're looking for a dedicated tool to compress image size without losing quality, this little app is actually a pretty solid find.
