About this tool

Turn raw phone or tablet captures into store-ready marketing images without a design account or cloud upload. Use deterministic templates, multilingual copy, official presets, optional generic device frames, batch zip export, policy hints, and alt-text drafts.

How to use this tool

Create a complete store screenshot package in one local workflow:

  1. Upload or paste up to six real app screenshots.
  2. Choose App Store or Google Play, then pick one export size for that store.
  3. Pick a template on the right, edit copy, adjust colors, and drag or scale the screenshot for that size.
  4. Switch stores to design Google Play or App Store separately; screenshot placement is saved per size.
  5. Export the current size for one screenshot or a zip for all loaded screenshots.

Features

Designed for the real mobile-app publishing workflow:

  • Twelve deterministic templates shared by live preview and full-resolution Canvas export.
  • App Store phone and iPad, Google Play phone and tablet, landscape, and 1024×500 Feature Graphic targets.
  • Up to six screenshots exported at the currently selected size.
  • Multilingual two-line typography with overflow protection.
  • Optional generic device frame, contain/cover modes, dragging, scaling, undo, and redo.
  • Screenshot color extraction and local preference memory without storing image files.
  • Google Play alpha, text-area, CTA, promotional-claim, and device-frame policy hints.
  • Browser-local processing with stable file names, publishing checklist, and alt-text drafts.

FAQ

Are screenshots uploaded?

No. Image pixels stay in your browser and are never sent to DevCove.

Can I export iOS and Android together?

Design each store separately: switch App Store or Google Play, pick one size, adjust placement, and export. Screenshot position is saved per size.

Do I need every iPhone screenshot size on App Store?

Usually not. Upload one accepted size per device group (for example 1320×2868 for 6.9-inch iPhone). Apple uses it across that group in App Store Connect.

Does the tool guarantee store approval?

No. It validates documented dimensions and provides policy hints, but final review belongs to Apple or Google.

What is saved locally?

Only small preferences such as template, copy, colors, selected targets, and device-frame setting. Screenshot files are not persisted.

Is Feature Graphic just a cropped phone image?

No. The 1024×500 target receives a dedicated horizontal layout and automatically disables the device frame.

What happens to metadata?

Canvas export normally removes EXIF and other source metadata.
