Transparent export
Make a rounded PNG with transparent corners.
White corner boxes usually happen when a rounded image is exported in a format that does not preserve transparency, or when a solid background was added by mistake. Use PNG or WebP when the corners need to stay transparent.
PNG, JPG, or WebP?
PNG is the safest choice for transparent rounded corners. WebP can also preserve transparency and often creates smaller files. JPG does not support transparency, so any empty corner area will be filled with a color.
Why transparent corners matter
Website backgrounds
Transparent corners let the page background show through naturally.
Slide decks
Rounded images can sit on colored slides without visible square corners.
Documents
PNG exports are useful when the document background is not pure white.
Social graphics
Transparent corners give you more control when placing images on templates.
Product mockups
Use transparency when screenshots are layered over cards or device frames.
Design handoff
A transparent PNG is easier for another designer or developer to reuse.
Common fixes
- If the corners look white, switch the export format from JPG to PNG.
- If the background is solid, set the background mode back to transparent.
- If the shadow creates too much empty space, turn shadow off before export.
- If the file is too large, try WebP with transparency.
