Default Opacity

The opacity describes the transparency level, which ranges between 0.0 and 1.0. An opacity of 0.0 is completely transparent, 0.5 is 50% see-through and 1.0 is opaque (not transparent).

The default opacity is 1 (no transparency).

Opacity Example

The examples below show the opacity of 1.0 (no transparency - default), 0.8 (20% see-through) and 0.4 (60% see-through).

Frequently asked questions

How do I change screenshot opacity?

Add &opacity=VALUE (0.0 to 1.0) to your Add Screenshots request to control transparency.

What happens if I omit the opacity parameter?

Opacity defaults to 1 (fully opaque). Lower values produce transparent backgrounds for overlays and design comps.

Can I combine opacity with other features?

Yes. Opacity works with scaling, cropping, grayscale, request templates, schedules, and cloud delivery in a single request.
