Is this HEIC to PNG converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple HEIC files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

How do I convert HEIC to PNG on Windows 11?

Drop your HEIC file into the converter above and click Convert — no download or install required. The conversion runs entirely in your browser using WebAssembly, so it works on Windows 11 without installing the HEIC codec or any third-party app.

Can I convert multiple HEIC photos to PNG at once?

Yes — drop in a whole batch and each HEIC is converted to its own PNG, then you can download them individually or as a ZIP. It's the fast way to unlock an entire camera roll's worth of iPhone photos for use on Windows, Android, or in an editor.

Why does my iPhone save photos as HEIC instead of JPEG?

Since iOS 11, Apple uses HEIC by default because it's about 50% smaller than JPEG at the same visual quality. You can change it in Settings → Camera → Formats → Most Compatible to shoot in JPEG instead.

Is my photo uploaded to your server?

Never. The conversion runs entirely inside your browser. Your files never leave your device — not even temporarily.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert HEIC to PNG?

Apple introduced HEIC (High Efficiency Image Container) in iOS 11. On Apple hardware, it's invisible — the camera shoots HEIC, the device displays HEIC, and everything feels normal. But the moment a HEIC photo leaves the Apple ecosystem, the problems start.

On Windows 10 and Windows 11, HEIC files require a paid codec extension to open in native apps. Without it, File Explorer shows a blank thumbnail, Windows Photos shows an error, and Paint won't load the file. Even with the codec installed, most third-party apps — GIMP, older Photoshop versions, Lightroom Classic before 2018 — still reject HEIC. Upload a HEIC to a government portal, a university form, or most e-commerce sites and you'll get a "file type not supported" error.

PNG is universally supported. Every operating system — Windows 11, macOS, Android, Linux — every browser, every image editor, and every web platform handles PNG without plugins or special settings. Converting HEIC to PNG gives you a pixel-accurate, lossless image you can open and use anywhere without compatibility headaches.

The best way to convert HEIC to PNG on Windows 11 (or any platform) is entirely in your browser: no download, no install, no codec — just drop the file and click convert. It works because the conversion runs in WebAssembly inside your browser tab.

Note: HEIC files are typically about half the size of an equivalent-quality JPEG. The resulting PNG will be larger — that's the trade-off for lossless, universal compatibility. If file size matters more than lossless quality, convert to JPG instead.

Common reasons to convert HEIC to PNG:

›Opening iPhone photos in Photoshop, Lightroom, GIMP, or any image editor on Windows or Mac
›Uploading iPhone photos to a website, portal, or CMS that rejects HEIC
›Sharing photos with Windows 11 or Android users who can't open .heic files
›Archiving photos in a format that will still open correctly in 10 or 20 years

Quality & file size: HEIC to PNG

HEIC to PNG is fully lossless: the HEIC is decoded and every pixel is written to the PNG exactly, so the result is pixel-for-pixel identical to what your iPhone captured — no re-compression, no artefacts. That's precisely why you'd choose PNG over JPG here when quality matters.

The cost is file size. HEIC is one of the most efficient photo formats there is — roughly half the size of an equivalent JPEG — while PNG is lossless, so the PNG can end up several times larger than the original .heic (a 2 MB HEIC photo can become a 6–10 MB PNG). That's expected: you're buying universal compatibility and zero quality loss. If a smaller file matters more than perfect fidelity — for email, a web upload, or a photo you'll just view — convert HEIC to JPG instead, which stays much closer to the original size.
