What is HEIC, and why convert it to JPG?
HEIC (High Efficiency Image Container) is the format Apple has used by default since iOS 11. It
is based on the HEIF standard and the HEVC codec, and it’s genuinely clever: a HEIC file stores
roughly the same image quality as a JPG in about half the file size. The catch is
compatibility. Windows, most Android phones, a lot of web upload forms, and
countless apps still don’t open HEIC reliably — so the moment you move a photo off your iPhone,
it often won’t open. Converting to JPG (JPEG), the most universally supported
image format on earth, fixes that instantly.
Why use SnapHEIC instead of an upload-based converter
Most online converters send your photos to a server, process them there, and send a file back.
For holiday photos, screenshots of documents, or pictures of your kids, that means handing your
private images to a company you’ve never heard of. In March 2025 the FBI even
warned that some
“free file converter” sites were a vector for malware and data theft.
SnapHEIC works differently. The HEIC decoder is compiled to WebAssembly and runs
inside your browser tab. Your photos are read from disk into memory, converted,
and offered back to you as a download — they are never transmitted anywhere. There’s no account,
no watermark, and no daily limit, and you can confirm the “no upload” claim yourself by opening
your browser’s developer tools and watching the Network tab while you convert.
Quality, color and metadata
HEIC can store 10-bit color and a wide Display P3 gamut with HDR data, while
JPG is 8-bit sRGB. When you convert, that extra range is mapped down into standard sRGB color —
which is exactly what you want for sharing, uploading and printing, because almost every screen,
printer and website expects sRGB. SnapHEIC respects the photo’s rotation so portraits don’t come
out sideways, and it strips the embedded EXIF metadata (including GPS coordinates) so your
converted JPGs don’t leak where they were taken. If you’d rather keep every last bit of detail
with no compression at all, convert to PNG instead, or read how to
convert without losing quality.
Works on Windows, Mac, iPhone and Android
Because it’s just a web page, there’s nothing to install. Open it in Chrome, Edge or Firefox on
Windows, in Safari on a Mac or iPhone, or in Chrome on Android. On Safari the conversion uses
Apple’s built-in HEIC support and is extremely fast; on other browsers SnapHEIC uses its bundled
WebAssembly decoder. Either way the result is the same: clean, shareable JPGs.
Tip: need a single document instead of separate images? Use
HEIC to PDF to merge several photos into one file, or keep maximum
quality with
HEIC to PNG.
Frequently asked questions
Is this HEIC to JPG converter free?
Yes — completely free, with no sign-up, no watermark, no email, and no daily limit. Because the conversion runs on your own device instead of a paid server, there is nothing to charge for. Convert as many photos as you like, as often as you like.
Are my photos uploaded anywhere?
No. The conversion runs entirely inside your browser using WebAssembly. Your HEIC files never leave your device — you can disconnect from the internet after the page loads and it still works. You can verify this yourself in your browser’s DevTools → Network tab, or simply switch on airplane mode and watch it keep working.
How do I convert HEIC to JPG on Windows?
Just open this page in Chrome, Edge or Firefox on Windows 10 or 11 and drop your photos in — there is nothing to install. It’s the simplest way around Windows’ patchy HEIC support. For other options, see our guide to opening HEIC on Windows 11.
Can I convert HEIC to JPG on a Mac, iPhone or Android?
Yes. On a Mac or iPhone, Safari decodes HEIC natively so conversion is near-instant; on Android, open the page in Chrome. The same page works on every device. See converting on iPhone or opening HEIC on Android.
How many photos can I convert at once?
As many as you want. Because everything happens locally, there is no file-count or file-size limit imposed by a server — you can drop in a whole camera roll and download them together as a ZIP. See our batch conversion guide. Very large batches on older phones may be slower, since the work uses your device’s memory.
Will converting to JPG reduce quality?
JPG uses lossy compression, so there is a small quality trade-off. SnapHEIC defaults to 92% quality, which is visually indistinguishable for photos. Use the quality slider to balance file size and fidelity (see converting without losing quality), or convert to PNG for a lossless result.
Does the JPG keep my photo’s location and metadata?
No — converting through the browser canvas strips EXIF metadata, including GPS location. That is a privacy benefit: the JPGs you share won’t reveal where the photo was taken.
Why are my iPhone photos HEIC in the first place?
Since iOS 11, iPhones default to HEIC because it stores the same quality in about half the space of JPG. The downside is compatibility. See our guide on why your photos are HEIC.
Is JPG the same as JPEG? Which one do I need?
They are exactly the same format — JPEG is the full name and JPG is just the three-letter file extension left over from old Windows systems. Any site or app that asks for a “JPEG” will happily accept the .jpg files this converter produces, so converting HEIC to JPG and HEIC to JPEG are the same task.
