Questions

Does converting JPG to PNG recover lost JPEG detail?

No. The conversion stores the existing decoded image in PNG format. It cannot reconstruct detail that the original JPEG compression removed.

Can I make a color transparent during JPG-to-PNG conversion?

Enable color transparency and choose the target color. The similarity control sets how broadly matching shades become transparent.

Why can the PNG file be larger than the JPG?

PNG and JPEG use different image representations and compression. Converting a photograph to PNG can increase file size without adding source detail.
