Frequently Asked Questions
Can I make the background transparent?
Yes. Transparent mode leaves pixels outside the rounded rectangle transparent and exports PNG. A selected solid background can be used instead. Source metadata and profiles are not preserved.
What is the maximum corner radius?
The control runs from 0 to 200 pixels, and the drawing API also clamps the effective radius to half the decoded width or height. A large radius rounds a rectangle into a capsule-like shape; only a square can become circular, so this is not equivalent for every source.
Does it support batch processing?
Yes. All selected JPG, PNG, or WebP images use the same requested radius and background setting and export as PNG. Different dimensions can cause the same pixel radius to look proportionally different across the batch.
