How to set transparency color?

Question:

I convert PNG files with transparency into jpeg file format. I want to specify the color to convert transparency.

Réponse:

To set transparency, you should add "Replace color" operation to the current profile and specify the color you want to replace with transparency.

The selected color will be replaced with transparency by default. If you want to replace color gradations, you should use "tolerance" option available in this operation.

Note: You should remember that not all graphics formats support transparency. For example, if you try to process a BMP file, you will see white color instead of transparency.
