JPG and JPEG are the same format. A JPG to JPEG conversion is not really converting anything, it is giving the file the four letter extension that some upload form, import folder or piece of software has decided it will only accept. The picture inside is unchanged.
Early Windows could only handle three character extensions, so .jpeg was clipped to .jpg and both spellings stayed in circulation. Decades later, a surprising number of systems check the name rather than the file, which is the only reason this page needs to exist.
The file is written out again, so strictly speaking it passes through the JPEG encoder a second time. At normal quality that is invisible on a single pass. What it does mean is that repeating the round trip over and over on the same image will slowly soften it, so convert from your original rather than from a copy of a copy.
Typing a new extension in a file manager works, right up until the moment it does not. Hidden extensions turn photo.jpg into photo.jpeg.jpg without telling you, and a few programs read the file header and ignore the name entirely. Converting sidesteps both problems, and doing a folder in one pass beats renaming forty files individually.
Straight to the .jpeg extension
Output is named the way the receiving system asked for it.
Mixed sources welcome
Files that are not already JPG can sit in the same queue and still come out as JPEG.
Sizes shown before and after
Each row reports both weights, so you can confirm nothing unexpected happened.
Free for any number of files
A single stray file and a folder of four hundred cost the same, which is nothing.

JPEG to JPG Converter
Give .jpeg files the shorter .jpg extension that many upload forms and older programs still require.
Only slightly, and it can go either way by a few kilobytes depending on how the original was encoded. Nothing you would notice.
It is closer to the standard's own name, but neither is wrong. Use whichever the thing you are feeding the file to expects.
No. A file that is genuinely damaged stays damaged, and it will simply fail in the queue rather than producing a working JPEG.
Some of it does not. If the shooting date and camera model matter to you, keep the original file alongside the converted one.
