Transparency
Transparent PNGs for overlays and UI tests
Does your upload path need alpha? The transparent image generator creates PNG or WebP files with controllable opacity — including a checkered preview.
Test the alpha channel on purpose
Many bugs only show up with semi-transparency: bad flattening, dark fringes, broken thumbnails. A controlled transparent test image makes that reproducible.
PNG and WebP
Pick the format your stack expects. WebP with alpha is common in modern browsers; PNG remains the classic for design and QA handoff.

Convert with the format converter or inspect metadata in the image inspector — all in the same toolbox.
