Reduce Image Size in KB

Reduce Image Size in KB makes a photo or signature fit the file size and dimensions an application form asks for, in one step. Set a range such as 10–20 KB or 20–50 KB, and optionally the width and height in pixels or centimetres (200 DPI by default, adjustable). The tool keeps the highest quality that still fits under the maximum. If a small image stays under the minimum even at the best quality, it adds blank comment data inside the file so it reaches the minimum without changing the picture. It never shrinks the picture without telling you. JPG, PNG, WebP and iPhone HEIC work, and the result can be saved as JPG, PNG or WebP. Everything runs in your browser: the image is never uploaded, and location and camera details are removed. Free, with no account.
