Wtf does this do

Snap Frame is a macOS app that turns plain screenshots into polished, ready to share images by adding a decorative frame around them. The idea is simple: you drop a screenshot into the app, choose a background style, tweak the visual details, and export the result as a PNG file you can share anywhere. The app supports drag and drop as well as a standard file picker, and it can also accept images copied to the clipboard. Once your screenshot is loaded, you can choose from several background presets: gradient fills, solid colors, or your current macOS desktop background. If you want something custom, you can set your own solid color or a two color gradient. The output can be sized to several common aspect ratios: Auto, 3:2, 4:3, 16:9, or 1:1. One convenient touch is that the app automatically detects the edge color of your screenshot and uses it for the inset frame, so the framing blends naturally with the image. You can also manually tune the outer padding, inset padding, corner radius, and shadow depth. Exporting is straightforward: use Command-S to save a PNG to disk, or Command-C to copy the rendered image directly to the clipboard. Command-R resets all settings back to defaults. The app is built in Swift and requires macOS 15.5 or later and Xcode 16 or later to build from source. It has no third-party package dependencies, so you just clone the repository and open it in Xcode. A prebuilt release is also available for download from the project's GitHub releases page.
