About This Tool

A 20KB limit is the strictest you will meet - passport photo systems, visa applications, and campus portals use it, and almost nothing you upload at original size will pass. This tool compresses any JPG or PNG down to 20KB or less using a quality slider with a live size preview, all inside your browser. It is the fastest way to make a tiny file without guesswork.

Frequently Asked Questions

What kinds of uploads actually require 20KB?

Passport and visa photo systems, some university portals, and a few government forms enforce 20KB ceilings. Those files are stored thousands of times over, so administrators keep them tiny.

Can any photo really reach 20KB without becoming unreadable?

A small, simple photo can, yes. The more uniform the background, the better it compresses. Use the slider and check the live preview - if the result looks too soft, start from a smaller pixel size.
