Sometimes you need an image that is both specific dimensions and a specific file size in KB. Our tool combines resizing and compression in one step, letting you set both target dimensions and a maximum file size. The intelligent engine first resizes your image to the requested dimensions, then iteratively adjusts compression to hit your KB target precisely. This is ideal for online forms, application portals, and platforms that impose both pixel dimension and file size requirements simultaneously. Upload any format — JPG, PNG, WebP, HEIC — and specify your target. The tool delivers the best possible quality within your constraints. All processing happens in your browser with complete privacy. No signup needed, no watermarks applied.
