HEIC to PNG Converter — Free, Lossless, In-Browser

Open the converter

This HEIC to PNG converter turns iPhone HEIC photos into PNG images with no compression artifacts and no upload to a server. PNG is the right choice when you need a lossless copy — for design work, screenshots that include text, or pictures with sharp edges and flat colors.

HEIC is fantastic for storage on an iPhone, but the moment you try to drop one into Figma, send it to a coworker on Windows, or paste it into a document, you hit a wall. PNG is the universal lossless format — every operating system, every browser, every image tool can open it without complaint.

The conversion happens inside the browser tab. Your photo is decoded by the same library Safari uses internally, re-encoded into PNG, and offered as a download. Nothing is sent over the network, so even sensitive screenshots or work-in-progress designs stay on your machine.

PNG files are larger than JPG because they preserve every pixel exactly. Expect a 5MB HEIC to become 15–25MB as a PNG. If you do not need lossless, the HEIC to JPG tool will produce far smaller files at near-identical visual quality.

Frequently asked questions

Is PNG really lossless from HEIC?

The PNG encoding step is lossless. The HEIC decode itself is what the iPhone produced — we cannot recover detail lost at capture time, but no further compression happens during conversion.

Are my files uploaded to a server?

Never. All processing happens locally in your browser. The site has no server-side conversion endpoint.

Why is the PNG so much larger than the HEIC?

HEIC uses modern HEVC compression. PNG uses lossless DEFLATE. A typical 12-megapixel photo grows from ~3MB to ~20MB. This is normal.

Does this work offline?

Yes — install as a PWA on first visit and all future conversions run without any network connection.

What is the file size limit?

25MB per file. The output PNG can be much larger; that download is unconstrained.
