Frequently asked questions

How can I get an image under 100 KB?

Lower the quality in steps and, if needed, also reduce the width in pixels. A 1000 pixel wide JPG at medium quality is often under 100 KB.

Which format is smallest?

For photos, WebP and JPG are the smallest. PNG is best for logos and screenshots with flat colours but is larger for photos.

Why is my photo a little under the target size?

The tool aims at or below your limit, so the result may be slightly smaller. That is fine for forms that set a maximum, but not for ones that need an exact size.

What if quality drops too much?

A very low size limit forces heavy compression, which makes the image blurry. Choose the largest size your form allows, or start with a smaller picture.
