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

If your goal is to compress image size without losing quality. Paint. NET is actually a best choice. It gives you manual control without being overly complicated. Unlike some basic editors that just crush your file into a mess, Paint. NET lets you decide exactly how much you want to shrink it. The magic happens when you go to save the file.

1. Do your edits: Crop, resize, add text—whatever you need.

2. Go to File > Save As: This is where the good stuff happens.

3. Pick the right format: This is key. If you choose PNG, it's going to be huge because it's lossless. To actually compress image size without losing quality (visually, at least), you want to pick JPEG .

If you really want to maximize that compress image size without losing quality goal, try these tricks:

Resize it first: If the image is huge (like 4000x3000 pixels), go to Image > Resize . Shrink it to something web-friendly like 1920x1080. Even at max quality, a smaller image is a smaller file.

Kill the "Exotic Matter": Sometimes images have hidden junk data (metadata) that bloats the file. A quick trick is to hit Ctrl+A (Select All), Ctrl+C (Copy), then Ctrl+Alt+V (Paste into New Image). Then save that new image. It strips out the digital cobwebs and usually makes the file smaller .
