Gradia is a native GTK4/libadwaita application that makes your
screenshots ready for sharing. Drop in an image and get back a
polished result: gradient, solid, or image backgrounds; padding,
corner rounding, shadow, and aspect-ratio presets; annotation
tools (arrows, shapes, text, highlighter, censor, and numbered
steps); crop mode; optional OCR text recognition; and direct
upload to configurable providers.
