App store screenshot compliance check

Pick stores, then drop the screenshots you plan to submit. Width, height, format and file size are read in the browser against the spec table — nothing is uploaded. Specs checked: 2026-10-15.

What this tool does

Before upload, pick stores and drop shots. Width/height, format, and bytes are read locally and checked against specs — green/red with reasons. Files never leave your device.

How to use

  1. Select stores (multi-ok).
  2. Drop or choose images.
  3. Review per-store results; jump to the maker when a preset size fits.

How we judge

  • Exact pixel matches; swapped orientation counts as the same rule.
  • Byte caps parsed from format notes (e.g. 5MB). “Under 1MB” means strictly less.
  • Huawei WEBP vs PNG/JPG caps differ by format.
  • Same dataset as Screenshot sizes; console wins on conflict.

FAQ

Are images uploaded?

No — dimensions/format/size are read in your browser.

Landscape and portrait?

Both — 1290×2796 and 2796×1290 count as the same size rule.

Google Play without fixed pixels?

We use the official range (320–3840, long ≤ 2× short). Feature graphic must be 1024×500.

PNG with alpha?

App Store/Play disallow alpha — we warn when alpha is detected.

Why vivo size is “console wins”?

Size isn’t confirmed on official pages — we don’t pass/fail size; format still checked.

Shot count checked?

No — only each file you provide.
