No upload. No account. No API key.
Everything runs locally in your browser.
AI image tools sometimes generate images that look transparent, but are actually exported with:
- a white canvas
- a baked-in checkerboard background
- no real alpha channel
RealAlpha helps turn those fake-transparent images into real transparent PNGs.
- Drop, click, or paste to upload
- Detects solid-color and checkerboard backgrounds
- Removes enclosed fake-transparent areas, such as holes inside rings
- Adjustable removal strength
- Local browser processing
- English / 中文 / 日本語 / 한국어
npm install
npm run devBuild for production:
npm run buildRealAlpha detects likely fake-transparent backgrounds from image borders, removes matching background regions, and applies light feathering around transparency edges.
It also handles enclosed background areas that simple edge flood-fill methods may miss.
