## About

Screenshot Studio is an open-source screenshot editor and mockup generator that runs entirely within the browser. It allows developers and designers to transform basic screenshots into professional graphics by applying gradient and mesh backgrounds, browser and device frames, 3D perspective transforms, and customizable shadows. The tool includes text and image overlays, tweet-to-image capture, code snippet formatting with syntax themes, and an animation timeline editor capable of exporting video formats like MP4, WebM, and GIF using FFmpeg WASM. Editing is processed locally on the device for privacy, with support for high-resolution PNG, JPEG, and WebP exports up to 5x scale without requiring user accounts or adding watermarks.
