HEIC is efficient, but compatibility is the tradeoff
HEIC can store high-quality iPhone photos in smaller files than older formats. The problem is not the image quality. The problem is that many tools still expect JPG or PNG.
Choose JPG for everyday compatibility
Use JPG when you need the image to work almost everywhere:
- Windows Photos and File Explorer workflows
- Android sharing
- Email attachments
- Insurance and support portals
- ID or profile photo uploads
- Printing and photo kiosks
JPG is lossy, but it is usually the practical answer when a form rejects .heic.
Choose PNG for a lossless browser-friendly copy
Use PNG when exact pixels matter more than small file size. It is a good fit for documentation, design review, UI screenshots, and workflows where you do not want another lossy photo generation.
Keep HEIC as the original
If the source came from an iPhone, keep the original HEIC file when possible. Convert a copy for the destination app, but preserve the original for storage and Apple Photos compatibility.
