The browser reads and transforms the selected file in local memory without uploading it to MW SysArc. The browser decodes the JPEG and writes a lossless PNG download. Conversion cannot restore detail already removed by JPEG compression. The selected file is processed in browser memory and is not uploaded to or stored by MW SysArc. Browser and operating-system limits still apply to large or damaged files.
