Transparent export
Make rounded corners transparent so the image still works anywhere you place it.
The most common export mistake is simple: the corner shape looks right in the editor, but once the image is placed on a site, slide, or document, square white corners appear around it. That usually means the final file was saved in the wrong format or with a solid background still applied.
Why white corner boxes happen
A rounded corner effect creates empty space outside the visible image shape. That empty space only stays transparent if the file format supports transparency and the export settings preserve it. If either step fails, the empty space gets filled with a color, usually white.
A clean transparency check before downloading
Set the background mode to transparent
If a solid background color is active, the file may still export with visible corner blocks even though the radius shape looks correct.
Pick PNG or WebP
PNG is the safer choice. WebP is worth trying when you want a smaller file and know the destination supports it comfortably.
Preview the file on a different background
The easiest test is to place the exported image on something non-white. Any leftover corner fill becomes obvious immediately.
Where transparent rounded corners matter most
Slide decks
Slides often use colored or branded backgrounds, which makes square corner artifacts much easier to notice.
Layered website sections
Transparent corners help screenshots and product images sit naturally on tinted surfaces, cards, or gradients.
Reusable assets
If one image may be used in docs, social posts, and decks, transparency gives you more flexibility later.
Product mockups
Transparent edges are especially useful when screenshots are placed inside frames or layered with shadows and padding.
