HEIC to PNG: Apple Photos in Lossless Quality with Transparency
Key Takeaways
- Converting HEIC to PNG preserves maximum image quality with lossless compression — ideal when you need pixel-perfect accuracy from your Apple photos.
- PNG format enables further editing without quality degradation, making it the best intermediate format for design and editing workflows.
- Unlike JPG conversion, HEIC to PNG avoids introducing any additional compression artifacts, maintaining the sharpest possible output.
When you need the highest possible quality from your iPhone or iPad photos, converting HEIC to PNG is the superior choice over JPG. PNG's lossless compression means zero additional quality loss during conversion, preserving every detail your Apple device captured. This matters most for professional editing workflows, graphic design projects, and any situation where you plan to further manipulate the image and want to avoid the cumulative quality loss of multiple JPG compressions.

Quality Advantage
When to Convert HEIC to PNG
Professional Photo Editing
When importing iPhone photos into Photoshop, Lightroom, or Affinity Photo for extensive editing, PNG as an intermediate format prevents cumulative compression artifacts.
Product Photography for E-Commerce
iPhone product photos destined for background removal and compositing should be converted to PNG to maintain crisp edges and enable transparency.
Screenshots and UI Documentation
iPad screenshots saved in HEIC format need PNG conversion for technical documentation where text clarity and pixel accuracy are critical.
Archival and Backup
For long-term photo archiving where format longevity and universal support matter, PNG is a safer bet than the relatively newer HEIC format.
Tips for HEIC to PNG Conversion
PNG files are significantly larger than HEIC or JPG. Only use PNG when you genuinely need lossless quality or plan to do further editing.
If your goal is simply sharing photos online or via email, HEIC to JPG is usually the better choice for smaller file sizes.
PNG preserves color depth and sharp edges perfectly — ideal for screenshots, diagrams, and images with text overlays.
Consider converting to PNG as a working format, then exporting to WebP or JPG for final web delivery.
All HEIC decoding and PNG encoding runs locally in your browser. No images are transmitted to any server, guaranteeing the privacy of your personal photos.
