How to convert a folder of files with GDAL TRANSFER?

Question

I have about 2000 images that need to be converted from TIF to JPG with some parameters using GDAL. I need to achieve this by using a CMD script. Here is my script so far:

set "SourceFolder=C:\Tif\newimages\"
set "DestinationFolder=C:\Tif\temp"
set "CreatedFolder="

if not exist "%DestinationFolder%\" (
    md "%DestinationFolder%" 2>nul
    if not exist "%DestinationFolder%\" (
        echo Error: Failed to create folder "%DestinationFolder%"
        goto EndBatch
    )
    set "CreatedFolder=1"
)
for %%N in (%SourceFolder%*.tif) DO gdal_translate -of jpeg -a_nodata 0 -b 1 -b 2 -b 3 %%i %DestinationFolder%\%%i*jpg

:EndBatch
endlocal
pause

This produces the following error message on CMD:

ERROR 4: %i: No such file or directory

Background:

Windows environment (obviously)
OSGeo4W cmd to run the script.

What I am looking for is an explanation of what I am doing wrong with the script and suggestions to make it functional.

Edit:

I realize that the commands at the end of the gdal line should be source and destinations of converted files. Is there any way around this as I would need to only define the destination folder at the end. I got it to work as an endless loop which was not optimal of course as the number of images is more than 2000.

Well after closer inspection, it turns out that I set a value for %%N and later tried to use %%i. Also, the gdal command should be this:

DO gdal_translate -of jpeg -a_nodata 0 -b 1 -b 2 -b 3 %%N %DestinationFolder%\%%~nN.jpg

Instead of:

DO gdal_translate -of jpeg -a_nodata 0 -b 1 -b 2 -b 3 %%i %DestinationFolder%\%%i*jpg
