Remove white in background of freehand drawing?

In what specific Corel application did you make the drawing?

If in CorelDraw, unless you drew on a white background like a filled with white rectangle, or colored specific objects in your drawing with white, there is no white color or background. The page color appears white, but actually has no color unless added.

If you export as an image, use either PNG with transparency or use TIFF with transparency, or export to PDF or another vector format as needed.

do you mean that you create a design with corelDARW and when export to JPG it has a white background? the JPG doesn't allows to use transparent background, then you should use TIF or PNG (for print or web) as Mike said
