How To Save an Image with a Transparent background in Krita

To save and export an Image in Krita, follow these steps:

Step 1: Select File > Save As

Step 2: Write the file name

Step 3: On the Image Extension option, choose PNG image (.PNG), then click Save

Saving image as a PNG image

Besides saving as a PNG file, you can save your image as a WebP file and a GIF file. Both image formats can save the transparent background on your image.

  • WebP is better than PNG because WebP images can be up to 30% smaller than the PNG counterpart at the cost of slightly reduced image quality.
  • GIF is not recommended because it’s for a moving image or animation. Saving a still image to GIF format is not the correct way to create a GIF image.
  • If you choose JPG, the transparent background will become a white background instead.
