A focused browser tool
IncreaseImgSize2KB is an independent image utility operated through increaseimgsize2kb.com. It was built to solve strict upload requirements without asking users to send private image files to a remote server.
How we test results
The tool processes JPG, PNG and WebP files in the current browser tab. Automated browser tests cover exact byte targets, maximum and minimum limits, transparency, format conversion, batch ZIP downloads, mobile layouts and invalid files. A generated result is decoded and its byte count is checked before download.
Editorial standards
Guides are written for practical image-upload problems and are reviewed against the behavior of the live tool. We distinguish file size from pixel dimensions and do not claim that adding bytes creates visual detail. Corrections and technical questions can be sent to support@increaseimgsize2kb.com.
