How to Convert HEIC to PNG (Lossless, With Transparency)
Why PNG Instead of JPG?
Most people convert HEIC to JPG, but there are good reasons to choose PNG. PNG is lossless — no quality is thrown away during conversion. If you're converting iPhone photos for editing, graphic design, or any workflow where you'll re-save the file multiple times, PNG prevents the generational quality loss that JPG introduces with each save.
How to Convert
Use CocoConvert's HEIC to PNG converter: upload your HEIC file, and download the result as a full-quality PNG. On Mac, open the HEIC in Preview and use File → Export, selecting PNG as the format. On Windows, after installing HEIF extensions from the Microsoft Store, you can open HEIC in Paint and Save As PNG.
File Size Differences
Expect the PNG to be 3-5× larger than the original HEIC. A 3 MB HEIC photo might become 12-15 MB as PNG. This is the trade-off for lossless quality. If file size matters more than perfect quality preservation, JPG is a better target — you'll get files roughly the same size as the original HEIC.
When HEIC to PNG Makes Sense
Choose PNG when you need: lossless quality for professional editing, images with transparency layers (rare for iPhone photos but possible), high-quality source files for print work, or archival copies where you want zero compression artifacts. For everyday sharing — email, social media, messaging — JPG is fine.
