About this skill
Gumroad Image Preflight checks the actual PNG, JPEG, or WebP files you plan to upload. It reports dimensions, ratio, format, mode, transparency, file size, and hashes; catches undersized, non-square, or reused compositions; and renders separate cover and thumbnail safe-zone previews. The result is PASS, REVIEW, or REWORK with exact file facts. It never signs in or uploads anything.
