Not clear. Why do you use PictireBox? Any benefits? Why setting BackColor to transparent? Did you really preserve transparency in PNG? How about a code sample?

Not Clear. If transparency is preserved in PNG, then it will not show white background. Hence, Code sample and the image used is required.

Follow three steps process to set the transparent color.

Step 1: Locate the constructor for your control class.

Step 2: In the constructor, call the SetStyle method of your form. This will enable your control to support a transparent backcolor.

C#

SetStyle(ControlStyles.SupportsTransparentBackColor, true);

Step 3: After the line of code you added in the previous step, set your control's BackColor to Transparent.

C#

this.BackColor = Color.Transparent;

Do This,

Set the backcolor of PictureBox to be same as the backcolor of the form on which it is.

Eg. if

C#

this.BackColor= Color.Blue;
pictureBox1.BackColor = Color.Blue;

Also try doing it once with some other image which has true transparency. Maybe your image does not have transparency!!
