Convert PNG to HEIC
This conversion runs the usual direction in reverse: PNG is the universally readable format and HEIC is the space-efficient Apple one. It makes sense when the files are headed into Apple's ecosystem and storage is the constraint.

Why Convert PNG to HEIC?
PNG is lossless and therefore large — it stores photographic detail without discarding anything, which is exactly why it is a poor fit for a phone photo library. HEIC applies HEVC compression and routinely lands a comparable-looking image at a fraction of the size.
The catch is compatibility, and it runs opposite to what most people expect here. HEIC needs an HEVC decoder, so a file that opens instantly on an iPhone may show nothing at all on Windows 10, on older Android builds, or in most web forms and email clients. PNG opens everywhere; HEIC does not. Convert in this direction only when you know the destination is Apple.
Transparency does not survive. PNG's alpha channel is one of its main reasons for existing, and the HEIC output produced here is flattened — so screenshots, logos and icons with transparent backgrounds will come out with those areas filled rather than clear.

- 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 free HEIC converter?
This one — free for files up to 50MB, or 100MB with an account, in both directions between HEIC and the common image formats.
Is HEIC better than PNG?
Better at being small, worse at being opened. HEIC uses a fraction of the storage for photographs. PNG is lossless, keeps transparency and is readable by everything. For photos going into Apple Photos, HEIC; for anything else, PNG.
How do I change my image to HEIC?
Upload the PNG above and choose HEIC. Apple devices produce HEIC natively but offer no way to convert an existing PNG into one, which is why this comes up.
How to convert PNG on iPhone?
iOS has no built-in format converter for images in the Photos app. The Files app and Shortcuts can do limited conversion, but there is no direct PNG-to-HEIC path — converting here is simpler.
Will transparency be preserved?
No. The HEIC output is flattened, so transparent areas will not stay transparent. If the image relies on an alpha channel, keep it as PNG or use WebP or AVIF, both of which support transparency and are far more widely readable.
Will the HEIC open on Windows or Android?
Windows needs the HEIF Image Extensions from the Microsoft Store. Android support varies by version and manufacturer. If either is a possible destination, PNG, JPG or WebP is the safer format.
