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.

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

Typical file sizes: HEIC 1.5–3 MB → PNG 8–25 MB.

Converting from lossy HEIC to lossless PNG will not recover detail the HEIC codec already discarded — but the output will not degrade any further. This is useful when you need a lossless format for editing or compatibility without additional compression artifacts.

Color depth: HEIC supports 12-bit, PNG supports 16-bit.

Transparency: HEIC supports transparency. PNG preserves transparency.

Your HEIC files are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
