Hi Product Hunt! I’m the maker of Compress to 100KB. I built this tool to help with a frustrating problem: an upload form rejects your image because the file is too large. Choose an image, set your target size in KB, and download the compressed result. Images are processed locally in your browser, with no signup or payment required. You can also set pixel dimensions and download batch results as a ZIP. The target is a maximum size, not an exact byte count. Smaller limits can reduce image quality or resolution, and the tool shows the actual output size. I’d love to hear how it works for your upload requirements, especially on mobile. If something goes wrong, please share your browser and the error message rather than private photos. Thanks for trying it!
