FEATURES
Everything you need.Nothing you don’t.
A fast capture tool, a real editor and a presentation layer that makes plain screenshots look designed.
Make it look finished.
Gradient and solid backgrounds, padding, rounded corners and window frames. Plain screenshots become presentation-ready in one click.
Shadows, your way.
Soft, medium or hard. Tune blur, distance, opacity and color until it feels right.
Redact for real.
Blur, pixelate or solid. Pixels are actually destroyed in every flat export, never hidden behind a removable layer.

Every capture can be a single .lumengrab file with the untouched original inside. Reopen it any time and keep editing.
Copy text from pixels.
Grab text or scan a QR code right from any screenshot. Recognition runs on your device.
