A free, offline-capable tool for creating polished App Store screenshots — right in your browser. No installation, no account, no cloud uploads. Just open the HTML file and start designing.
Device Presets iPhone 6.9" (1320×2868), iPhone 6.7" (1290×2796), iPad 13" (2064×2752), iPad 12.9" (2048×2732) — portrait and landscape.
Backgrounds Two- or three-color gradients with direction control, solid colors, or custom background images with blur and darken effects. Includes 10 ready-made gradient presets.
Device Frames Realistic dark or light device shells with Dynamic Island for iPhones. Adjustable size from 45% to 95%.
Text Overlays Headline and subtitle with independent font sizes, adjustable gap, free X/Y positioning, and manual line breaks via Enter. Four built-in fonts: Nunito, Poppins, Playfair Display, and Noto Sans TC. Italic toggle included.
Per-Image Settings Each screenshot has its own headline, subtitle, text position, image position, and tilt angle (-30° to +30°). One-click copy to apply settings across all images.
Batch Workflow Upload up to 10 screenshots at once (click or drag & drop), navigate with thumbnails or arrow keys, and export individually, all at once, or in all four device sizes with a single click.
Apple-Ready Export All exports are opaque RGB PNGs — no alpha channel, no App Store Connect rejections.
Trilingual Interface Full UI in English, German (Deutsch), and Traditional Chinese (繁體中文), switchable with one click.
100% Offline All fonts are embedded as Base64. The entire tool is a single 1 MB HTML file with zero external dependencies.
