Document Background and Transparency Adjuster

Select or drop a document image (JPG/PNG) or a PDF file (first page).
Choose background style, then decide if you want binarization.
If not binarizing, you can adjust the White Scale (0-255) pre-gamma and Gamma Correction,
and choose output type (grayscale or preserve colors).
If binarizing, only a binarization threshold is available.

Or drag and drop a file into this window.
