Kromia is a screenshot maker for app developers. Build your set on one panorama canvas with device frames and modern templates, then export every size the stores require — exact pixels, sRGB, no alpha channel. Designing is free.
Lay out every screenshot on a single continuous canvas. Artwork and headlines can flow across slide boundaries for a connected panorama, or stay per-slide — your call.
Drop your app screenshot into a phone or tablet frame, tilt it in 3D, and it stays sharp at any export size. Generic hardware, no manufacturer marks.
Export iPhone 6.9″ and 6.5″, iPad 13″, and Google Play dimensions at the precise pixels App Store Connect and Google Play require — no manual resizing.
PNG or JPEG, sRGB colour, and no alpha channel — the exact format the stores accept, so uploads don't get rejected for transparency or a missing colour profile.
Start from bold, current templates and swap in your screenshots, or build from a blank canvas. Curated Google Fonts, gradients, and shapes included.
Sign in to save projects to the cloud and open them on any machine. There's an API and an MCP server too, so an AI assistant can build screenshot sets for you.
Upload the screens from your app, or paste them straight from the clipboard.
Drop screenshots into frames, pick a template, add headlines, and arrange them on the panorama canvas.
Download every required size as a zip — correct pixels, sRGB, no alpha — ready to upload.

Kromia is a browser-based tool for designing App Store and Google Play screenshots. You build your screenshot set on a panorama canvas with device frames, text, and templates, then export the images at the exact pixel sizes each store requires.
iPhone 6.9″ (1320×2868) and 6.5″ (1284×2778), iPad 13″ (2064×2752), and Google Play (1080×1920), among others — at the precise dimensions App Store Connect and Google Play require. Everything downloads as a single zip.
Yes. Designing is completely free — every template, frame, and asset, unlimited projects, saved to your account. You only need a paid plan to export the finished images.
Exporting is $7.99 per month, $49.99 per year, or $199.99 once for lifetime access. You can cancel a subscription anytime from your account page.
No. Start from a template, drop in your app screenshots, and adjust the text. Everything is drag-and-drop, and the export sizes are handled for you.
Yes. Files come out at exact store pixel dimensions, in sRGB, as PNG or JPEG with no alpha channel — the format the stores accept. That avoids the common rejections for transparency or a missing colour profile.
Just a web browser — it works on macOS, Windows, Linux, and ChromeOS. Nothing to install. Rendering and export happen on your own device.
