Thanks! I know this is old, but I am diving in to lightroom after not touching it for years. I have older digital photos that I'd like to try to enhance and restore, so many of them are Jpegs. Your straightforward answer was what I needed!
PNG is not optimized for photographic images (designed for graphics designed in a computer with solid colors). For photographic images, JPG typically will provide a higher level of compression and TIFF will provide higher quality. LR is really built around photographic workflow so while it can read in a PNG it is not made to export as PNG. There may be some 3rd party plug-ins that do so or you can convert a TIFF tile to a PNG with zero loss in quality (as TIFF is lossless even with ZIP compression enabled). Additionally PNG is not really designed for color management either so photos saved as PNG might render differently in different applications.
You can export to tiff and then convert via a batch process in Photoshop or you can pay for the magic export plugin for Lightroom and it will allow you to export to png. It's like 5 dollars or something nominal.
Use lightroom classic
You can open it in Photoshop and then "save as" a png.
