Free, in-browser phone mockup tool. Drop a mobile screenshot or screen recording, get a transparent PNG or GIF in seconds. Includes 3D tilt with depth (Rotato-style), drop shadow, shine, and an eyedropper to sample frame colors from your screenshot. No account, no upgrade prompts. Unlike most mockup tools, transparent backgrounds are free — exactly what you need for decks, READMEs, and social posts.
