About this tool
Choose PNG over JPG when you plan to edit the photo further, need a lossless copy, or are handing an image to a tool that only accepts PNG. Expect files five to ten times larger than the original HEIC; that is the cost of lossless storage.
About the formats: HEIC (High Efficiency Image Container) has been the default photo format on iPhones since iOS 11. It stores photos at roughly half the size of JPG at the same quality, but Windows, Android apps, and most websites will not accept it without conversion. PNG (Portable Network Graphics) is a lossless image format with full transparency support. It is the standard choice for screenshots, logos, icons, and anything with sharp edges or text, but it produces much larger files than JPG or WebP for photographs.

Questions
Is HEIC to PNG lossless?
The PNG stores exactly the pixels decoded from the HEIC, so no further quality is lost. The HEIC itself was already lossy when the camera saved it.
Why is the PNG so much bigger?
PNG does not throw any information away. A 12-megapixel photo is typically 2-3 MB as HEIC and 15-30 MB as PNG.
