Preparing file upload...
PNG uses lossless compression — zero quality degradation during conversion. JPG is lossy and introduces compression artifacts. If you need perfect quality from your iPhone photos, PNG is the right choice.
PNG supports alpha transparency while JPG doesn't. If you need to use iPhone photos as overlays, in designs with transparent backgrounds, or for compositing, PNG preserves transparency.
If your HEIC files contain screenshots, text overlays, or graphics, PNG preserves sharp edges perfectly. JPG compression blurs high-contrast edges — the "fuzzy text" problem.
For regular photos where file size matters more than pixel-perfect quality, HEIC to JPG produces much smaller files (3-5x smaller than PNG). Use PNG for:
| HEIC | PNG | JPG | |
|---|---|---|---|
| Compression | Lossy (efficient) | Lossless | Lossy |
| File size | Small | Large (3-5x JPG) | Medium |
| Quality | Excellent | Perfect (lossless) | Good at 90%+ |
| Transparency | Yes | Yes | No |
| Device support | Apple + modern Android | Universal | Universal |
Yes — typically 3-5x larger for photos. PNG is lossless (no quality loss) while JPG is lossy (smaller but some quality lost). Choose based on your priority: quality or file size.
