Good to know: Works locally in your browser with JPG, PNG and WebP. No images are sent to the server. Maximum 10 MB per file, 8 megapixels and 4096 pixels per side. Up to two images only for comparison; other tools use one. Outputs have the same pixel size unless the tool explicitly changes it. Static images only; animation and original metadata are not preserved. Keep your original files.

How to use it (step by step)

  1. 1Choose a color image.
  2. 2Create the three channel previews; each shows the intensity of one RGB channel.
  3. 3Download individual PNGs or the ZIP. These are RGB channels, not CMYK print separations.

Resolution / pixels
A picture is made of tiny dots called pixels. 1080×1920 means 1,080 dots wide and 1,920 tall.

Picture file types. JPG is best for photos, PNG for graphics and see-through backgrounds, WebP is newer and smaller.
