No. Everything runs in your browser - your file never leaves your device. How this is verifiable
HEIC is the iPhone default that many programs cannot open. PNG is the right choice when you need lossless quality or transparency - for screenshots, graphics or further editing.
Decoding runs locally in the browser (libheif) and exports PNG. Your photos are never uploaded.
Unlike converting to JPG, PNG keeps every pixel exactly, because PNG compresses losslessly using the Deflate method. That matters when you reuse text, screenshots or diagrams from a HEIC - JPG artefacts around sharp edges show up immediately there. Note, though, that a photo saved as PNG needs noticeably more space than the compact HEIC original, because PNG is not optimised for photographic content.

Limitations: PNG files are larger than JPG, especially for photos. For small photo files, HEIC to JPG is usually the better fit. The output is 8-bit sRGB. Apple's "HDR" photos already store the visible image at 8 bits and keep the extra dynamic range separately as a small gain map plus metadata, applied only when viewed on an HDR-capable screen - that gain map is not carried over, only the 8-bit base image comes out.
Whenever pixels must survive exactly: screenshots with text, diagrams, logos or images you plan to edit several more times. For transparency there is no way around PNG either - JPG has no alpha channel. For ordinary photos to share or print, HEIC to JPG is the smaller choice.

No, PNG is lossless. No detail is lost.
PNG is lossless and packs photos less tightly than HEIC or JPG: as PNG a photo often takes five to ten times the size of the HEIC original, because HEIC compresses with HEVC video technology while PNG keeps every pixel exactly. If a photo should stay small, HEIC to JPG is the better choice; PNG pays off for graphics, text and transparency.
The visible pixels are carried over fully; embedded metadata such as capture date or location is usually not written into the PNG export - handy when you want to share the image without those details.
