How to Compress an Image

An image compressor reduces the size of supported image files using the available compression settings. GlobalToolHub's free browser tool lets you select an image, adjust the settings, and download the result. Compare the output with the original before replacing it, because compression can change image quality and may not always produce a smaller file.
