Help for the iPhone Duo mockup generator.

Which files can I upload?

Use one PNG or JPEG up to 20 MB, 20 megapixels, and 10,000 pixels on either edge. HEIC, SVG, GIF and PDF files are not supported.

What is the difference between Fit and Fill?

Fit shows the entire screenshot inside the screen. Fill scales it to cover the screen and may crop the edges.

Does my screenshot leave my browser?

No. The image is decoded and composed locally in the current browser page. Refreshing or closing the page clears the work.

Which PNG sizes are available?

Choose 2560 × 1920 for the full marketing canvas or 1280 × 960 for a smaller file.

Can I submit the PNG to the App Store?

No. This tool creates marketing visuals. App Store screenshot export sizes are not supported.
