HEIC often gets converted too early because teams assume every downstream system will reject it. That is not always true. Some platforms preserve HEIC perfectly well, which means an unnecessary conversion only creates extra work and potential quality loss.
The better question is whether the actual destination can use the file today. If it can, keep the original and convert only when a real compatibility boundary shows up.
When conversion is necessary, the image type decides the fallback. For camera photos, JPG is usually the right answer because it preserves compatibility and keeps file sizes practical.
If the source is a screenshot, scan, or graphic with text and hard edges, PNG is often safer. Otherwise the resulting JPG can look softer than the original in ways users notice immediately.
Convert once, review once, and only compress after the destination is confirmed. Repeated exports are where visible degradation usually starts to accumulate.
Keep the untouched HEIC original for future reuse. That matters when a client later asks for a print version, a larger crop, or a different output format.
