PLATFORM IMAGE REQUIREMENTS
Official image specifications
Platform requirements can change. Check the official documentation before submitting your assets. This tool separates app icons, screenshots and promotional images because one image is not suitable for every asset type.
Specification sources checked: November 1, 2026. Output sizes marked as recommended are practical presets, not a claim that the platform mandates that exact resolution.
Frequently asked questions
Does this tool upload my images?
No. Image decoding, resizing, format conversion and ZIP creation run in your browser. The tool does not upload your source image.
Can one image create every type of store asset?
No. An app icon, a product screenshot and a promotional graphic serve different purposes. Upload the appropriate original image for each purpose.
Will the generated images guarantee store approval?
No. The tool checks dimensions and supported output formats. Store approval may also depend on content, design, transparency, file-size and other current platform rules.
Why do some platforms offer more than one screenshot size?
Platforms support different device families and orientations. Select only the outputs relevant to the devices your app supports.
What do PWA icons do?
PWA icons are referenced by a web app manifest so a website can be installed and displayed like an app. Chromium installable PWAs need suitable 192 × 192 and 512 × 512 icons; you still need to add the generated files to your site and reference them in the manifest.
