Runs in-browser · no uploads

1.Upload any PNG image with or without transparent alpha channels.
2.Choose your preferred background fill color (e.g. solid white) and compression quality.
3.The browser rasterizes the composite onto canvas and exports a lightweight JPEG.

You can choose your background fill (white, black, or custom color) so transparent pixels render cleanly without accidental black backgrounds.
