How to compress a JPG to 100 KB
A 100 KB limit is common for photos and document images on application portals. This page is set to 100 KB and finds the best-quality JPG that fits, usually without changing the photo's dimensions at all.
Add one or more images.
Leave 100 KB selected.
Click Compress images and download the JPGs.
Document images and profile photos
100 KB is enough for a full-resolution phone photo of a document or a sharp profile picture, so most images reach it with only a quality adjustment and no change in dimensions. It is a common limit for ID scans uploaded as images, for profile pictures on portals and for product or listing photos on small marketplaces.
Add several images at once if you have a set to prepare; each is compressed individually to fit, and they download together as a ZIP when there is more than one.
PNG screenshots and scans
Screenshots and scanner output are often PNG files of several megabytes. The tool converts them to JPG, which is far smaller for photographs and scans; the trade-off is that very fine lines and flat colour areas can show slight artefacts. For a form upload that is fine. If a recipient specifically requires PNG, this is not the tool to use.
