Method, example & boundaries
Convert a local raster image among JPEG, PNG, and WebP while choosing the destination format deliberately. The page keeps format choice separate from resizing: it previews the decoded result, reports the actual file size, and makes transparency loss visible before download.
One 800×300 PNG that retains transparent pixels, with a new measured byte size.PNG is selected because the target system accepts it and transparency matters. JPEG would flatten transparent areas and should be chosen only with an intentional background.
The source is decoded to canvas pixels, then the destination MIME type and quality are passed to the browser encoder. The downloaded extension follows the actual encoded Blob type; the process does not rename bytes to pretend that a format changed.
