Key Features that Make FrameOS Indispensable

FrameOS is packed with features tailored to streamline your workflow and enhance your visual output:

  • Diverse Frame Styles: Choose from a variety of popular operating system and device frames, including macOS (traffic-light chrome), Windows 11 (Fluent title bar), Minimal (shadow card), Browser (Chrome-style tab), Phone (Samsung Galaxy slim bezels), and Tablet (iPad wide bezel). This versatility ensures your screenshots always match the context of your presentation.
  • App Store & Google Play Formats: For mobile app developers, FrameOS is a game-changer. It exports images at the exact pixel dimensions required by both Apple App Store (e.g., 6.7” iPhone 15 Pro Max: 1290 × 2796 px) and Google Play Store (e.g., Standard 9:16 Android: 1080 × 1920 px), simplifying your submission process.
  • Batch Processing: Upload up to 10 images at once and navigate through them with ease. FrameOS allows you to apply settings across multiple images and export them all in a single click, saving you valuable time.
  • Customizable Backgrounds: Personalize your mockups with 4 built-in gradient options (Cosmic, Sunset, Forest, Midnight) or select any solid color to perfectly complement your brand or design.
  • Fine-tuned Canvas Controls: Adjust image scale (50–100%), padding (8–64 px), and corner radius (0–32 px) to achieve the perfect look for your framed screenshots.
  • Flexible Export Options: Download your framed images as high-quality PNGs, export all processed images at once, or copy them directly to your clipboard for quick pasting into other applications.
  • Client-Side Processing: Your privacy is paramount. All image processing is done entirely in your browser. Your images never leave your device, ensuring complete data security and fast performance.
  • Intuitive User Interface: With a clean design, dark/light mode toggle, and keyboard shortcuts (← → for navigation, E for export, Ctrl+Z for undo), FrameOS offers a seamless and efficient user experience.
