Upload an image, enter exact dimensions or a percentage, keep the aspect ratio, and download the resized file as JPG, PNG, WebP, or AVIF.
Does resizing reduce image quality?▾
Shrinking an image usually looks identical at normal viewing sizes. The main quality risk is enlarging beyond the original resolution.
