The Short Answer
HEIC is built for storing photos efficiently on Apple devices — small files, good quality, native support across iOS and macOS. PNG is built for universal compatibility and lossless precision — larger files, but it opens in every editor, browser, and operating system, and supports transparency, which HEIC doesn't.
Format Overview
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11, built on the HEVC video codec. It stores photographs at roughly half the file size of JPG at comparable quality, which is why Apple made it the default camera format.
PNG has been a web and graphics standard since 1996. It uses lossless compression and a full alpha channel for transparency, making it the default choice for screenshots, logos, and any image that needs to be edited further without quality loss.

When to Use HEIC
Stick with HEIC while a photo stays inside Apple's ecosystem — on your iPhone, backed up to iCloud, viewed on a Mac. It saves significant storage space without a noticeable quality trade-off for everyday photos.
When to Use PNG
Use PNG for anything that needs transparency, further editing, or guaranteed compatibility — design assets, screenshots, logos, or images bound for a website, a Windows PC, or software that doesn't recognize HEIC at all.
When to Convert HEIC to PNG
Convert when a photo needs to open in an editor that doesn't support HEIC, get uploaded to a site that rejects it, or get shared with someone on Windows or Android without compatibility issues. Our HEIC to PNG converter handles this entirely in your browser, producing a lossless file with nothing uploaded to a server.
