    What changes when JPEG becomes PNG

    • The tool decodes each JPEG and writes a PNG with the same pixel dimensions.
    • PNG adds no further lossy compression, but it cannot restore detail or transparency already lost in the JPEG.
    • The PNG may be larger than its JPEG source; this conversion does not promise a smaller file.
