- Solid backgrounds or diagonal gradients between two colors
- 0–256px padding and 0–80px rounded corners

Frequently asked questions
Does this tool capture my screen?
No. You choose an image you have already saved. The tool does not request screen sharing or recording permission.
How are the output dimensions calculated?
The original width and height are retained, with padding and shadow space added to each side. Soft shadow adds 30px per side; deep shadow adds 60px per side. The optional window bar adds 12–36px of height according to the source width.
How are transparency and rounded corners handled?
The chosen background or gradient shows through transparent source pixels and outside the rounded boundary. Shadow is drawn only outside the card, without filling its interior black. The resulting background is opaque.
Is the window frame an exact browser window?
No. It is a decorative bar with three colored dots above the card. It does not add an address bar, app name or operating-system information, and it does not change the screenshot’s content.
Why can a large source image fail during composition?
Both source and output must stay within 8,192px per side and 20 million pixels. Adding padding, shadow or the window bar can push a near-limit image beyond the output limit. Reduce these settings or choose a smaller source.
How do reset and clear differ?
Reset restores the default background, padding, shadow and frame while keeping the selected image. Clear releases the source and generated result. After settings change, create a new PNG instead of downloading the previous result.
