Frequently asked questions
How does the 100KB tool work?
The tool encodes the image at several quality levels and shrinks large dimensions when needed, then returns the best result that fits under your target.
Which format gives the smallest file?
WEBP is usually the most efficient for photos. JPG is a good choice when you need wider compatibility.
What if the image is already smaller than 100KB?
The tool keeps the original when it already fits the target, so you get a quick result without unnecessary changes.
