About Image Resizer
Image Resizer changes the pixel dimensions of an image. Width and height are locked to the source aspect ratio by default — type a new width and the height adjusts to keep the image undistorted. Resampling uses the browser's high-quality canvas interpolation, so downscaled output stays visually clean.
Resizing changes dimensions; it isn't the same as compressing to a specific file size. If you need to hit a 100 KB target rather than a pixel target, use Image Compressor instead — it adjusts JPEG quality to fit a size goal. Upscaling beyond the source resolution will look soft, since the resizer can't invent detail that wasn't captured.
