Need to compress an image to 100KB? This free online compressor reduces any JPG or PNG to 100KB or smaller in seconds — right in your browser, with no watermark, no sign-up, and no software. Just upload, and the tool automatically finds the right quality (and downscales if needed) to hit your target size while keeping the image as sharp as possible.
Why compress to 100KB?
Many websites and forms enforce a maximum file size, and a photo straight from a phone or camera is usually far too big. Compressing to 100KB is ideal for web pages, email attachments, and forms that cap uploads at 100KB. Instead of guessing at a quality slider, you set the target and the tool does the math — binary-searching the compression level and, for very small targets, gently reducing the dimensions until the file fits under 100KB. It's free and unlimited, so you can compress as many images as you need.
