PNGMaker
Narrow on purpose and better for it - generating a genuine alpha channel rather than a white box you have to key out saves a real step for anyone making slides, stickers or overlays. Ten free credits a day makes it usable without paying. The vendor is anonymous, the terms dodge naming a jurisdiction, and there is no API, so it stays a manual tool.
Pros
- Outputs a real transparent alpha channel, not a white background to remove later
- Resolution up to 4K with a choice of five aspect ratios
- Style presets covering kawaii, 3D cartoon, flat illustration and pixel art
- Commercial use permitted and a privacy toggle on generations
- Ten free credits every day rather than a one-off trial
Cons
- No company name, address or jurisdiction anywhere on the site
- Terms say only that disputes follow the law wherever it operates, without naming where
- No API, batch mode or integration with design tools
- Credit-to-image ratio (about 6 credits per PNG) makes the entry plan roughly 200 images
