Why Convert PNG to HEIC?
HEIC is Apple's default iPhone photo format since iOS 11, built around space-efficient photo storage on Apple devices. Converting from PNG — built around graphics, logos, and screenshots needing sharp, exact detail instead — closes that gap.
HEIC was built around space-efficient photo storage on Apple devices, which is precisely the gap PNG leaves open, since it's designed around graphics, logos, and screenshots needing sharp, exact detail instead.
PNG works well for graphics, logos, and screenshots needing sharp, exact detail, but has a real limitation: larger file sizes than lossy formats for photographic content. Converting trades that for this: roughly half the file size of JPG at similar visual quality.

- MiConvert converts it to HEIC, aiming to preserve what makes HEIC useful: roughly half the file size of JPG at similar visual quality.

Frequently Asked Questions
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
What happens to features specific to PNG that HEIC doesn't have?
PNG's real strength — lossless compression plus full alpha transparency support — has no equivalent once converted, since HEIC's constraint is: many Windows programs and non-Apple platforms can't open it directly.
Is HEIC objectively better than PNG?
Not objectively — HEIC is better specifically for space-efficient photo storage on Apple devices. For graphics, logos, and screenshots needing sharp, exact detail, PNG is still the right tool; that's exactly why both formats exist.
What's the real difference between PNG and HEIC?
PNG is built around graphics, logos, and screenshots needing sharp, exact detail (a lossless raster format with alpha transparency). HEIC is built around space-efficient photo storage on Apple devices instead (Apple's default iPhone photo format since iOS 11) — different enough that this is a genuine format conversion, not just a rename.
Why does HEIC exist as a separate format instead of everyone just using PNG?
Because they're built for different jobs — PNG is aimed at graphics, logos, and screenshots needing sharp, exact detail, while HEIC is aimed at space-efficient photo storage on Apple devices. Neither format is "better," they just fit different parts of a workflow.
