Read guide →Screenshot maker FAQ
Are my screenshots uploaded?
No. Image editing and ZIP generation happen locally in your browser. Analytics never receives image contents, filenames, or your custom captions.
Is the screenshot maker free?
Yes. The current editor requires no account, adds no watermark, and does not limit the number of local exports.
Can I use the exports in App Store Connect?
Each iOS PNG uses the selected Apple pixel dimensions. Dedicated iPhone Duo uploads are planned for later in 2026; check App Store Connect availability before submitting.
Does it support Google Play?
Yes. Choose Android Phone or Android Tablet to generate opaque PNG screenshots using Google Play-friendly dimensions.
Which app-icon formats are included?
You can export Xcode AppIcon.appiconset or an Android Studio resource pack with mipmaps, adaptive icons and the Play listing icon.
What size should an app screenshot be?
For iPhone, start with the current 6.9-inch App Store category. For Google Play phones, 1080 × 1920 in 9:16 is a practical recommended format. The size selector includes additional accepted options.
Build the listing without leaving the browser.
Use editable templates, exact platform presets, custom copy, and local ZIP export.
