Are my images uploaded to a server?

Can I compress an image to exactly 100 KB or 20 KB?

Yes. Enter the target KB and the tool reduces quality until the file is at or below that size.

How to compress an image to a target KB

Upload a JPG or PNG, then either set a quality level or type a target size in KB. The tool re-encodes the image right in your browser, lowering quality step by step until it reaches your target size. Optionally set a maximum width to resize large photos — perfect for online forms that demand "photo under 100 KB" or "signature under 20 KB".
