How to Convert HEIC to PNG (Lossless)

Yes — any HEIC file can be converted to lossless PNG using image conversion software. HEIC to PNG is the right choice when you need pixel-perfect quality, transparency, or plan to edit the image further.

Why convert HEIC to PNG

PNG is lossless. Every pixel of the original HEIC is preserved exactly, with no compression artifacts. That's the reason to pick PNG over JPG:

You want pixel-perfect quality for editing, printing, or archiving
You need a transparent background (logos, graphics, UI assets)
You're saving the image as a source file you'll convert to other formats later
You're submitting to a system that only accepts PNG (some CMS, design tools, government forms)

3 ways to convert HEIC to PNG

1. Install Windows 11's free HEIF Image Extension

After installing the free HEIF Image Extension from Microsoft Store, the built-in Photos app can open HEIC and save as PNG. Works for individual files, but no batch mode — you'll be right-clicking and saving one at a time. If you can't install Store apps (work PC, school device), this option doesn't exist for you.

2. Use an online HEIC to PNG converter

Websites like CloudConvert and Convertio convert HEIC uploads to PNG. They work for one-off files, but every photo uploads to their server, gets processed, then comes back. Most cap file size at 25–100 MB. Your photos sit on a stranger's server for hours. For lossless PNG (which is much larger than JPG), the file size cap matters even more — one iPhone photo can easily exceed the limit.

3. Use EasyImg (desktop, lossless, batch)

EasyImg is a desktop app for Windows and Mac that converts HEIC to PNG entirely on your computer. Drag in a folder of iPhone photos, pick PNG, click Convert. The output is bit-identical to the decoded HEIC pixels — no quality loss, no compression artifacts. 200 photos take a couple of minutes. EXIF and color profiles are preserved by default. No upload, no file size limit, no internet required.

How to convert HEIC to PNG with EasyImg

Drop in your HEIC files

Files, folders, or both. EasyImg reads HEIC natively — the Windows HEIF extension isn't required.

Pick PNG as the output format

No quality slider — PNG is always lossless. Toggle EXIF on or off depending on whether you need camera metadata.

Click Convert

Files land in the same folder with the original name plus the .png extension. Duplicates skipped, filename conflicts auto-renamed.

HEIC to PNG — common questions

Yes — the conversion itself is lossless. Every pixel of the decoded HEIC is preserved exactly in the PNG output. Note that HEIC itself uses lossy compression, so the original photo already has some compression artifacts baked in. PNG just preserves what's there, bit-for-bit.

HEIC uses advanced compression to keep file size small. PNG uses lossless compression, which preserves every pixel exactly — and that takes more space. A 12-megapixel iPhone HEIC at 3 MB typically becomes a 15–25 MB PNG. If file size matters more than lossless quality, use HEIC to JPG instead.

HEIC files from the iPhone camera don't actually have transparency (the iPhone shoots photos, not graphics). The conversion itself supports alpha channels, so if you ever feed EasyImg a HEIC with transparency, the PNG output will have it too.

PNG when you need lossless quality, transparency, or plan to edit further — the file is 5–10× larger than JPG. JPG when you need smaller files for sharing, uploading, or archiving — there's a small quality drop that's invisible at quality 90+. Use HEIC to PNG for editing source files; use HEIC to JPG for everything else.

Yes. EasyImg preserves the embedded ICC color profile (usually Display P3 on iPhone) so the PNG displays the same colors in any app that respects color profiles. Most online converters strip the color profile to save bandwidth, which can shift colors slightly in professional workflows.

Yes — the iPhone's built-in Files app or Shortcuts can do single files, but with the same downsides as the Windows HEIF extension: no batch, one tap per photo. For libraries of dozens or hundreds of photos, a desktop tool like EasyImg is much faster.

Other conversions you might need

Bottom line

Pick HEIC to PNG when you need lossless quality, transparency, or a source file for further editing. The file is 5–10× larger than JPG, but the pixels are preserved exactly. For everything else — sharing, uploading, archiving — use HEIC to JPG instead. EasyImg handles both locally, so your photos never leave your computer regardless of which output format you pick.
