Why PNG won't open
Most "won't open" issues are format mismatches (the extension says PNG but the bytes say otherwise) or unsupported variants (a specific sub-flavor of PNG the receiver's software doesn't handle).
Converting to JPG with PNG to JPG re-encodes the content into a clean, standards-compliant file. Whatever weirdness the original had, the output of PNG to JPG is a fresh, well-formed JPG.
