How it works
ResizeKit opens your PNG in the browser canvas and exports it as a JPG file. You can choose quality and the background color used for transparent areas.
JPG is often smaller than PNG for photos and complex images, but it does not preserve transparency.
Privacy
The conversion happens locally in your browser. The PNG is not uploaded to any server.
Limitations
JPG is lossy and cannot keep transparent pixels. Use PNG or WebP if transparency is required.
