Frequently Asked Questions
What format does the output use?
PNG, because only PNG supports the transparent corners that result from the rounded clipping.
Can I set different radii for each corner?
Currently all four corners use the same radius. Per-corner control may be added in a future update.
Will this add a white background?
No. The corners are fully transparent in the PNG output.
