Backgrounds
Gradient, solid color, or transparent. Built-in gradient presets (Brand, Sunrise, Ocean, and more), custom from/to colors, and angle control.
Pro feature
CaptureKit Studio
Turn raw screenshots and screen recordings into marketing-ready frames. Add gradients, canvas sizes, padding, shadows, and separate camera layers — then copy, save, or export video with audio. Everything runs locally in your browser.
Included with Capture Kit Pro. Free users keep core capture & preview annotations.
What you can do
Studio works with screenshots and videos from Capture Kit. Open it after capture, from History, or from the popup when you have Pro.
Canvas size
Auto-fit content, Square, Full HD, Widescreen, Open Graph (1200×630), HD, Portrait, or fully custom width and height.
Frame polish
Padding (0–200px), corner radius, and shadow strength (None, Soft, Medium, Strong) so shots feel finished for docs, social, and demos.
Camera layer
When you record with camera, Studio keeps a separate camera track. Move, resize, mirror, and pick rectangle, square, or circle — without re-recording.
Video player
Play/pause, scrubbable timeline, time display, and mute while previewing the composed canvas. Export uses high-resolution scaling for quality.
Export
Images: copy to clipboard or save PNG. Videos: export with background and mixed audio (mic) when present. Files stay on your machine.

How to open Studio
-

Privacy
Studio processes media entirely on your device. Screenshots and videos are not uploaded for composition. Pro billing uses Lemon Squeezy; the extension only sends a license key to validate Pro access — never captures or page content.
