Why do rounded image corners look black in one app and white in another?
KitForma editorial guide. The corners created by https://kitforma.com/en/image-round-corners/ are transparent, and the viewing app chooses what appears behind them.
Step-by-step guidance
The corners created by https://kitforma.com/en/image-round-corners/ are transparent, and the viewing app chooses what appears behind them. Inspect the PNG on both light and dark backgrounds before assuming the pixels are black. If you need a fixed white background, flatten onto white through a suitable conversion and verify the result. Exporting to JPEG removes transparency; preserving rounded transparent corners requires a format and destination that support it.
