Resize images to exact dimensions

Resizing is separate from compression: you change pixel width and height (or max edge) while keeping a usable level of detail for print, web, or document templates.

ImageOptimizer resizes in the browser with WASM—files are processed on your device. Choose a tool for passport specs, email signature blocks, or a consistent max width for galleries.

After resizing, run a compress tool if you still need a smaller file size for upload limits.
