JPG and JPEG are the same format: lossless mode only changes the extension. Re-encode if you also want to adjust quality and file size.

Download .jpeg files
Download each file or all of them as a ZIP.
JPG vs JPEG
JPG and JPEG are the same format. JPEG is the name of the standard from the Joint Photographic Experts Group, and .jpg exists only because early versions of DOS and Windows limited file extensions to three letters. Programs read both extensions the same way, and the image inside is identical.
Still, some systems are strict: a website form, a camera utility, an archive specification or a script may require exactly .jpeg. Renaming files one by one is tedious, and some converters silently recompress the picture. The default lossless mode here copies the JPEG data bit for bit with all metadata and simply gives each file the .jpeg extension.
If you actually want to change the file, choose Re-encode: the photos are decoded and saved again at the quality you pick on a 10–100% slider, which is a quick way to make large camera images lighter. Add many files at once and download them individually or as a single ZIP.
