Image Resizing

Resize pixel dimensions with browser Canvas and export WebP, JPEG, or PNG. Files stay in the current browser tab and are not uploaded.

Output Rules

  • Lock the original aspect ratio or set both dimensions independently
  • JPEG cannot preserve transparency, so transparent pixels are filled white
  • Quality applies to JPEG and WebP; PNG is encoded losslessly by the browser
