Why Convert HEIC to PNG?

HEIC is what your iPhone saves by default, and while it is space-efficient, it will not open in a lot of editors and it is lossy. Converting to PNG gives you a lossless file with an alpha channel, which is what you want before editing or when you need a transparent background.

The photo will not gain back detail HEIC already compressed away, but from this point on nothing degrades.

Frequently Asked Questions

Can I convert HEIC to PNG in the browser?
No. Browsers cannot decode HEIC, so this pair runs in the desktop app through macOS's native sips tool. The conversion is still 100% local; nothing is uploaded.
Should I pick PNG or JPG for my HEIC photos?
PNG is lossless and supports transparency, which suits editing and graphics work. JPG is far smaller and better for sharing plain photos. Choose PNG when quality and a transparent canvas matter more than file size.
Will the PNG be larger than the HEIC?
Yes, usually much larger. HEIC is a highly efficient lossy format, and PNG is lossless, so the same image can grow several times in size after conversion.
Why does my iPhone save HEIC in the first place?
Apple adopted HEIC in iOS 11 because it stores photos at roughly half the size of JPG at similar quality. You can switch future photos to JPG under Settings, Camera, Formats, Most Compatible.
Is my file still private in the desktop app?
Yes. The desktop app converts with native engines on your Mac and works offline after a one-time activation check. Nothing is uploaded, in the browser or on desktop.

Converting a camera roll for editing?
