Just tested it on demo-basic.pimcore.org (advanced currently not working), works as expected...

[SameerPCore]

Please upload a JPG file and edit and save it. then download it from either download button of toolbar or original file button present on the right panel. The error is very much there. this error is occurring because while editing the format is changed to PNG but the extension of file remains JPG.

@brusch It works fine if you try to open image on Windows default image viewer but reproducible on some softwares so maybe Linux is affected. @SameerPCore is right, this is the issue https://stackoverflow.com/questions/11310220/why-am-i-getting-the-error-not-a-jpeg-file-starts-with-0x89-0x50
