Does converting JPG to PNG improve quality?

No — it cannot restore detail that JPG compression already removed. What it does is stop further loss: every later edit and save of a PNG keeps the image exactly as it is.

Why is the PNG larger than the JPG?

PNG stores every pixel without lossy compression, while JPG throws detail away to stay small. The larger file is the price of an image that no longer degrades.

Can I convert many images at once?

Yes. Add as many JPGs as you need in one go, and each comes back as its own PNG, named after the original file.
