How to export App Store screenshot sizes

A polished screenshot set can still fail a release checklist when one file is the wrong dimension or format. A preset-based export keeps the final mile predictable.

1. Start from the target size

Do not resize a finished image by eye. Begin with the platform preset so the composition is designed for the final canvas and text remains legible.

2. Use a three-point review

• Dimensions match the selected App Store family.
• Text and device details remain readable.
• No transparent pixels, accidental crop, or low-quality source image remains.

3. Keep the batch organized

Use stable ordering and descriptive filenames. That makes it easy to compare a new release against the previous set and catch a missing locale or device family.

4. Export with confidence

FrameLoom includes App Store size presets and a repeatable batch export workflow, so a single composition can become a complete upload set without guesswork.
