What is a HEIC file?
HEIC is the format iPhones and iPads have used for photos since iOS 11. Built on the HEVC video codec, it stores photos at roughly half the size of an equivalent JPG — but outside the Apple ecosystem support is patchy. Windows needs paid codecs, many websites reject HEIC uploads, and most printing services will not accept it.
In short, HEIC is Apple's iPhone photo format. It is best for staying on Apple devices — for everything else, convert it first. Its main limitations are poor support on Windows, Android, the web, and most upload forms; licensing restrictions keep adoption low.
Why convert HEIC to PNG?
PNG is a lossless format designed for the web. Every pixel is preserved exactly, and its alpha channel supports smooth, variable transparency — which is why logos, icons, and UI screenshots are almost always PNGs. The tradeoff is file size: photographs saved as PNG can be several times larger than an equivalent JPG.
Converting from HEIC to PNG makes sense when you need logos, icons, screenshots with text, diagrams, and any image that needs a transparent background. PNG is universally supported in every modern and legacy browser.
Both formats support transparency, and this converter preserves the alpha channel — transparent areas in your HEIC stay transparent in the PNG.
Because PNG is lossless, the conversion will not add any new compression artifacts — but it also cannot restore detail the original HEIC compression already discarded.
How to convert HEIC to PNG
Drag and drop one or more HEIC files into the box above (or click to browse). Then press Convert. Each file is decoded and re-encoded as PNG on your own device in a second or two, and you can download results individually or grab everything as a ZIP.
Unlike most online converters, FileLark never uploads your files to a server. The conversion runs entirely inside your browser using modern web technology, which means it works offline once the page has loaded, there are no file size queues or daily upload limits, and your images can never be stored, scanned, or leaked — they simply never leave your device.
