Resize vs. compress
Resizing changes the dimensions (pixels); compressing reduces the file size at the same dimensions. For the smallest files, resize first, then use our Image Compressor.
Frequently asked questions
Will resizing reduce quality?
Making an image smaller keeps it sharp — this tool uses high-quality smoothing. Making an image larger than its original size can't add detail, so it may look soft.
