Convert HEIC to PNG
Drop your HEIC files and get pixel-perfect PNG copies, decoded and re-encoded entirely inside your browser. Useful when you need to edit a photo in software that requires PNG, paste a transparent-friendly format into a design tool, or archive a screenshot without further compression.
How to convert HEIC to PNG
- Drop one or more HEIC files into the box below.
- The libheif decoder unpacks each frame and a Canvas re-encodes it as PNG, all in your browser.
- Download the PNG copies individually or as a batch.
Why convert HEIC to PNG?
PNG is the right destination format when you cannot afford any quality loss after the conversion. Unlike JPG, PNG uses lossless compression, so the converted picture is bit-for-bit identical to the decoded HEIC frame. This matters for screenshots, diagrams photographed from a whiteboard, scanned documents, charts, product photography that you intend to retouch, and anything you plan to convert again later — every JPG round-trip degrades the image, while PNG round-trips do not. The price of lossless storage is file size: a typical iPhone photo that takes 1.5 MB as HEIC will land somewhere between 6 and 12 MB as PNG. If you simply want a portable, smaller, web-friendly file, prefer the HEIC to JPG converter instead.
How we compare
The closest peer to this tool is Google's Squoosh, which also runs fully in your browser. Squoosh focuses on compression for the modern web and does not handle HEIC or batch conversion. Cloudconvert and Convertio cover more formats but upload your files to their servers and meter usage.

Frequently asked questions
Is PNG really lossless?+
Yes. PNG uses DEFLATE compression which never throws away pixel information. The output is mathematically identical to the decoded HEIC frame.
Why is the PNG so much larger than the HEIC?+
HEIC stores the same picture using modern lossy compression that achieves roughly 50% smaller files than JPG. PNG keeps every pixel, so a typical iPhone photo grows by 4–8x.
Are my photos uploaded?+
No. Everything runs in your browser tab. Open the network panel in DevTools to confirm zero outbound traffic during conversion.
Can it preserve transparency?+
iPhone photos do not contain transparency, but if the HEIC came from a screenshot or designed image with an alpha channel, it is preserved in the PNG output.
Does it work on mobile?+
Yes on Android Chrome and modern iPhone Safari, but very large files may exceed iPhone Safari's per-tab memory budget.
Is the tool open source?+
Yes. The full source is on GitHub under AGPL-3.0 and you can self-host the converter if you prefer.
