1242×2688 px PNG
Design assets often have to ship at a single canonical size — an icon set, a profile picture, a thumbnail — because platforms or frameworks will reject anything off-spec. App Store Screenshot · iPhone 6.5" produces 1242×2688 PNG, the size App Store Screenshot · iPhone 6.5" expects.

How iOS App Store ranks images: App Review checks dimensions, content, and lookalike rules. Posting at the platform's exact native dimensions (1242×2688 px) preserves your original framing and avoids the softening that happens when the platform's own resampler runs to fit its expected size.
Platform-specific note: App Store screenshots render at exactly the device-specific size; submitting at the wrong resolution will fail App Store Connect's intake validator.
This preset is a deterministic recipe — every step has fixed parameters so the result is byte-identical across runs of the same input.
App Store Screenshot · iPhone 6.5" crops your input to 1242:2688 and resizes it to 1242×2688 px as PNG — a 3.3-megapixel output. The work runs through canvas APIs and a WebAssembly image-encoder; the source image is decoded into an off-screen canvas, transformed in place, and re-encoded without any network upload.
Design deliverables to clients often require an exact pixel-size; this preset's deterministic output makes the deliverable repeatable. The browser-side path also means the file never leaves your device — relevant when the input contains personally identifiable information, screenshots of private documents, ID scans, or proprietary product photography.
1242×2688 px, saved as PNG.
The target platform — see the cited spec — uses 1242:2688 as its native frame. Submitting any other ratio means the platform's own crop runs, which often clips faces or text near the edge.
PNG preserves hard edges and transparency that JPEG would smear. Icons, logos, and screenshots compress better as PNG when the image isn't photographic.
No. This preset runs entirely in your browser using WebAssembly + canvas APIs — no server round-trip. You can verify this in your browser's network panel: only static asset requests, no image upload. The file never leaves your device.
