How to Use

Upload your image

Click the upload area or drag and drop an image. Supported formats are JPG, PNG, and WebP.

How to Calculate

Conversion decodes the source pixels and re-encodes them in the target format. Transparency survives PNG to WebP, while JPEG flattens alpha onto white, so the tool warns before lossy jumps.
