Refbox
Always-on-Top Floating Frames
This is the cornerstone feature of Refbox. Users can pin any image, video, GIF, or note into a resizable frame that floats above all other application windows. This ensures your reference material is always visible right beside your working canvas, whether you're in Photoshop, Blender, or a code editor. Frames can be minimized, locked in place, or auto-hidden to clean up your workspace, providing ultimate control over your desktop real estate and focus.
Comprehensive Media Support & Organization
Refbox supports a wide array of media types beyond standard images. You can import and view videos, animated GIFs (with playback controls), SVG files, and even take instant website screenshots by pasting a URL. All media is organized into customizable Collections within a sidebar, allowing you to separate references by project, client, or theme. Drag-and-drop makes building and managing these collections intuitive and fast.
Advanced Creative Utilities
The app includes a suite of specialized tools that cater to professional creative needs. This includes a color picker to sample colors directly from any reference media, an image cropper to focus on specific details, and pixel rendering mode for authentic pixel art viewing. For motion work, you can scrub through GIFs frame-by-frame. Notes support Markdown formatting and checklists, making it easy to add textual context or task lists alongside visual inspiration.
Streamlined Workflow Shortcuts
Refbox is designed for keyboard-driven efficiency. You can quickly swap between floating references using arrow keys, change collections with a single click, and use customizable global shortcuts to show, hide, or manipulate frames without touching the mouse. These little touches, like copying media to the clipboard or saving it directly to your system, save countless clicks and hours over a long project, keeping you in a productive rhythm.
