As long as you get a result and are happy with it.
as the thread title "Batch conversion from JPG to PNG"
Whichever way you do your corrections you decided to end up with a jpeg. Is that your reduce size? That only reduces the file size by a lossy-jpeg compression. Nothing to do with the image size.
As my previous remarks, for whatever reason BIMP adds an alpha channel to the png output*. You can remove alpha to your hearts content but when the end of the pipeline is the BIMP procedure to write a png file you get an alpha channel. I know I tried various this morning for a different result.
* I did write a bug report but this is probably a 'catch-all' default. There will be some conversions where an alpha channel is required.
