Fanontaniana apetraka matetika
Why does this tool only download PNG?
PNG supports alpha transparency. JPG does not preserve transparent pixels.
Does opacity change image dimensions?
No. The output keeps the same dimensions as the source image.
Nampiakarina ve ny sariko?
No. Your image stays in your browser and opacity adjustment runs locally.
