App Frames

A simple browser-based tool that turns in-app screenshots into App Store and Google Play marketing assets. No account, no backend — upload, customize, export.

Try it live: klippros.com/tools/app-frames

How it works

1. Upload one or more screenshots
2. Preview framed assets (toggle iOS / Android preview)
3. Customize per frame (title, position, replace, reorder) and globally (gradient hue, device bezel)
4. Export a ZIP of store-sized JPEGs

Privacy

All processing happens in the browser. Your screenshots never leave your device.

Development

pnpm install
