LookFrame

LookFrame is a free, browser-based screenshot generator for the App Store and Google Play. Design each slide once - screenshot, headline, background - and export a complete, correctly sized set of PNGs for every device and every language of your project. No install, no account, no upload: your files never leave your machine.

Key features:

• Multi-device export: native-resolution PNGs for iPhone 6.7", iPhone 6.5", iPad Pro 13" and standard Android phones in one click, plus any custom size via the device manager.
• Multi-language projects: each slide keeps its text per language, and the export ships every market with its own files, named to match Apple and Google conventions.
• Auto-fit titles: headlines resize automatically so nothing gets truncated on smaller screens. Per-line color, alignment and letter-spacing.
• Real gradient backgrounds: any CSS linear, radial or conic gradient, rendered on canvas at full resolution.
• Per-screenshot framing: crop, zoom and pan each screenshot directly on the canvas, or apply one framing to all slides.
• 8 ready-made templates and reusable style presets shared across projects.

Everything runs locally in the browser. On Chrome and Edge, LookFrame works directly in a folder you choose on your disk, so your workspace is just files you can back up, sync or version. On Firefox and Safari it uses the browser's private storage, with one-click ZIP export and import. There is no server-side processing, no cloud, no account and no fees.

The interface is available in 9 languages (English, French, Spanish, Portuguese, German, Italian, Russian, Chinese, Japanese).
