What is Compress an image to 10KB?
TL;DR: Type 10 KB as your target and Shrink44 binary-searches the quality (and resolution if needed) to land at or just under 10KB — without uploading your image.
Reaching a 10KB ceiling is a common requirement for tiny signature and icon uploads on strict portals. Most compressors only give you a quality slider; Shrink44 lets you set 10KB as an exact target and does the maths for you.
It works by iteratively binary-searching the encoding until the output lands at or below 10KB, all inside your browser — so even sensitive ID photos never touch a server.
