How to compress a JPG to a specific size
Online forms often limit photos and signatures to 20–100 KB. Pick the limit and this tool finds the sharpest JPG that fits — it only shrinks the image's dimensions when it has to. Everything happens on your device.
Add one or more images (JPG, PNG, WebP, GIF or BMP).
Choose a size limit, such as 50 KB, or type your own.
Click Compress images and download the JPGs.
