Sometimes you need an 图片 that is both specific dimensions and a specific 文件大小 in KB. Our tool combines resizing and compression in one step, letting you set both target dimensions and a maximum 文件大小. The intelligent engine first resizes your 图片 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 文件大小 requirements simultaneously. 上传 any format — JPG, PNG, WebP, HEIC — and specify your target. The tool delivers the best possible 质量 within your constraints. All processing happens in your browser with complete privacy. No signup needed, no watermarks applied.
