Questions
About Round Corners
Why is the output a PNG?
The cut-away corners must be transparent, and JPG has no transparency. PNG and WebP both keep it; choose WebP for smaller files.
Is the radius the same on every image?
Yes — the radius is in pixels, so images of the same size get identical corners. Resize first if you want a perfectly uniform set.
Are my files uploaded?
No. Wemute converts files inside your browser tab with your device's own processor. The file contents and names never reach our servers, and nothing is kept after you close the page.
