Start with dimensions, not quality
If the source image is much larger than the destination needs, resizing it down gives you the cleanest file-size win.
Only after the dimensions feel correct should you push quality lower.
Guide
Compress in the right order.
Bad compression usually comes from changing too many things at once. A better workflow is to control one variable at a time so you can see what actually hurts the image.
Use this guide with OpenToolsKit's image compressor when you need a smaller file but still want a clean preview.
Pick the right format
JPG is usually the safest option for photos when you need a tight KB limit.
PNG is better for very simple graphics or signatures, but it is usually worse for hitting exact low-KB targets.
Use the preview as your real checkpoint
A target size matters, but the preview tells you whether the file is still useful.
If the image falls apart before reaching the requested cap, keep the smallest clean result and adjust the dimensions or target.

Short answers that keep the workflow moving.
Is WebP always the best choice?
Not always. It often compresses efficiently, but JPG is still safer for compatibility.
Why reduce dimensions first?
Because huge source files often waste pixels that the destination never needs.
