Black and White JPG to Transparent PNG


To create an image with a transparent background that's black and white, the process is simple. Open your image. Select Layer>Transparency>Add Alpha Channel.


Now select Layer>Transparency>Color to Alpha. Since you are removing white, you don't need to change the color. Note: if this was a color image, any color containing white, the white will be removed, giving the colored areas an opaque effect, or in the digital scrapbooking world - vellum quality.


If you want this new image to be a brush, then go to Image>Mode>Grayscale. In 2.2 you go to Script-Fu>Selection>To Brush. Name the brush and the script will create it and add it to your currently selected brush. In 2.4 go to Edit>Copy>Paste As Brush. Name it and it'll pop up in your brushes tool box. Making it grayscale will allow the brush to take on the currently selected color in your palette. More about brushes were posted elsewhere.

Be sure to save your finished product as name.png - if you save as a jpg you'll get the white background again.

Thanks for sharing very interesting tutorial about change color of any print. This information can be helpful in making our images very innovative. Apply photo effects and enhance them through image masking, photo retouching & restoration, flat lay and colour correction by using photo Editor.

> colour to alpha is greyed out

For me as well.

Wonder if it's because my image is grayscale (Color->Desaturate on an original colour image)?

That perhaps removed "colour" information?

"colour to alpha is greyed out"

This can happen if the image is color-indexed. Under IMAGE->MODE make sure RGB is selected.
