Convert Apple HEIC to PNG — in your browser, no upload

Turn Apple HEIC RAW files into PNG — lossless, pixel-perfect — all at once. Files never leave your device; everything is decoded right here in your browser. No sign-up, no watermark, no limits.

What is an HEIC file?

HEIC is the photo format the iPhone has used by default since iOS 11 — Apple's name for an image stored in the HEIF container, compressed with HEVC. It packs the same picture into about half the size of a JPG, which is great on your phone but awkward everywhere else: Windows often can't open it, many websites and upload forms reject it, and Android phones may not show it. So the moment you move an iPhone photo off the phone, you usually need a JPG.

What is PNG, and why convert HEIC to it?

PNG is a lossless image format: it stores every pixel exactly, with no compression artifacts. It is universally supported and is the format of choice when you need a perfect copy of the developed image — for editing, archiving, or placing graphics over a clean background — rather than the smallest possible file.

Convert Apple HEIC to PNG when you want a lossless render you can edit repeatedly without quality loss, or a clean master to hand to a designer. Unlike JPG, a PNG won't introduce blocking or ringing around edges, so fine detail and text stay crisp. The trade-off is size: PNG files are large (often several times bigger than a JPG of the same image). Pixadel decodes the HEIC fully and writes a true-colour PNG with no recompression.

Why convert HEIC with Pixadel

The usual fixes are clumsy — email the photo to yourself to force a JPG, change a phone setting you'll forget, or install yet another app. Pixadel just converts it: drop your HEIC files and get JPGs back, all in the browser. Nothing uploads, there's no account or limit, and you can do a whole camera roll's worth at once into a single ZIP. It works the same on Windows, Mac, Android or anywhere with a browser.

How HEIC → PNG conversion works

Pixadel decodes each HEIC with libheif compiled to WebAssembly — the same engine behind many native HEIC viewers — then re-encodes a clean JPG at the quality you choose (default 92), with an optional half-size export. Because everything runs locally, your photos never leave your device. A memory-aware worker pool converts many files in parallel and streams them into a ZIP, so a full import of hundreds of iPhone photos finishes without uploading a single byte.

Frequently asked questions

Why is the PNG so much larger than a JPG?
PNG is lossless — it keeps all pixel data instead of discarding detail to save space. Expect a PNG to be several times the size of a JPG of the same HEIC. Use PNG when fidelity matters more than size; use JPG to share.
Does converting HEIC to PNG lose any quality?
No. The HEIC is fully developed and the result is stored losslessly, so the PNG is a pixel-exact copy of the rendered image — there is no quality setting because none is needed.
Why won’t my iPhone photos open on Windows or the web?
iPhones save photos as HEIC, a newer high-efficiency format many apps and sites don’t support yet. Converting to JPG makes them open everywhere. Pixadel does this in your browser without uploading anything.
Can I convert a whole camera roll at once?
Yes — drop a folder of HEIC files and Pixadel queues them all, converts in parallel, and hands you one ZIP of JPGs. There’s no cap on file count.
Are my photos uploaded to a server?
No. HEIC decoding runs entirely in your browser via libheif (WebAssembly). Your photos never leave your device — refresh the page and they’re gone.
Does converting lose quality, and what about location data?
You set the JPEG quality (default 92), and the image is fully decoded before re-encoding. The output JPG carries no metadata, so GPS and EXIF are dropped automatically — handy before sharing. To inspect or remove metadata while keeping a file, use the EXIF tool.
