ScreenBuilder
App Store and Google Play screenshots, built in your browser
ScreenBuilder is a free screenshot maker for mobile app listings. Upload your app screenshots, place them in a modern iPhone or Pixel frame, add a headline and a background, and export pixel-perfect images for the Apple App Store and Google Play. Everything runs in your browser: your images are never uploaded.
How it works
- Pick the store (App Store or Google Play), the output size and a phone frame.
- Upload one or many screenshots. Each becomes a slide. Add a title and choose a colour, gradient or image background.
- Move, resize and rotate the phone with the mouse, then export all slides as a ZIP of PNG or JPEG files.
Features
- iPhone 17 Pro, iPhone Air and Pixel 10 Pro frames with several finishes, drawn as sharp vectors.
- Exact store sizes. App Store: 1320 x 2868, 1290 x 2796, 1260 x 2736. Google Play: 1080 x 1920, 1440 x 2560, 1080 x 2160.
- Headline in Nebula Sans with weight, size, alignment, colour and an optional box behind the title.
- Drag the phone, resize the screenshot inside it with handles, and pick a screen fill colour.
- Edit all slides at once or override a single slide. Undo and redo are built in.
- 24-bit PNG export without alpha channel, JPEG export and a store requirement check before download.
- No account, no watermark and no upload. Your project is saved locally in your browser.
Frequently asked questions
Is ScreenBuilder free?
Yes. There is no account, no watermark and no limit on exports.
Are my screenshots uploaded to a server?
No. Everything is processed in your browser. Your images, text and settings stay on your device and are saved locally in your browser storage (IndexedDB).
Which screenshot sizes does it export?
For the Apple App Store: 1320 x 2868, 1290 x 2796 and 1260 x 2736 pixels (iPhone 6.9 inch class). For Google Play: 1080 x 1920, 1440 x 2560 and 1080 x 2160 pixels.
Which phone frames are available?
iPhone 17 Pro, iPhone Air and Google Pixel 10 Pro, each with several colour finishes. The frames are drawn as vectors, so edges stay sharp at any export size.
Does it follow App Store and Google Play requirements?
Exports are the exact pixel size you choose and PNG files are 24-bit RGB without an alpha channel. Before export, ScreenBuilder checks the number of screenshots, the size limits and screen aspect ratio and shows warnings. Always confirm the final rules in App Store Connect and Google Play Console before submitting.
Can I edit all screenshots at once?
Yes. The All slides mode applies title, background and phone settings to every slide. Switch to This slide to override a single slide, and use undo and redo to step back.
