App Store Connect wants screenshots at specific dimensions per device class. If you ship in five languages and need 6.9" + 6.5" + iPad 13" coverage, that's 5 panels × 5 languages × 3 device sizes = 75 files. Hand-exporting and renaming is the slow part. The ZIP names files 01-panel-name.png in folders 6.9", 6.5", iPad 13", etc. — drop the right folder into App Store Connect per device class.
Every official App Store Connect size: 6.9" (1320×2868), 6.7" (1290×2796), 6.5" (1242×2688), 5.5" (1242×2208), iPad 13" (2064×2752), iPad 11" (1668×2388), Pixel 8 Pro (1344×2992), Galaxy S24 (1080×2340). The editor re-renders each panel at exact dimensions per size; no upscaling, no blurry export.
If you have multiple App Store locales enabled, the ZIP can include "every panel × every locale" as folders named with App Store canonical codes (en-US/, pt-BR/, zh-Hans/, etc.). Translation happens once (see AI translation); export pulls the localized text per locale.
PNG-24 with alpha. Sub-100KB per panel for typical designs. SVG-based 3D tilt renders cleanly into PNG because the export uses the live DOM tree via a foreignObject SVG wrapper into a canvas.
