Why iPhone photos will not open on Windows
Since 2017 iPhones have saved photos as HEIC instead of JPG. It is a genuinely better format — roughly half the file size at the same quality — but Windows, most websites, and a lot of older software still cannot read it. That mismatch is why "HEIC to JPG" remains one of the most searched conversions on the internet nearly a decade later.
One honest detail about HEIC specifically: the decoder this site uses hands back a high-quality JPEG, which is then re-encoded into whatever you asked for. So converting a HEIC always costs a little quality, even when the destination is PNG. For every other input format the conversion is a single encode, exactly as you would expect. You can set the quality below. The first HEIC file takes a moment longer while the decoder loads from this site; everything after that is fast.
What happens to your colours
iPhones photograph in Display P3, a wider range of colour than the sRGB that most software assumes. Many converters ignore this: they read the numbers out of the file and label them sRGB without translating them. The picture that comes back is measurably duller than the one that went in, and the more saturated the subject, the worse it gets — a red sign or a green leaf loses its life.
This converter reads the colour space your file actually declares, and hands the browser what it needs to translate correctly. We checked the result against a reference colour engine: every patch landed within one or two levels out of 255. Files that declare no colour space at all are treated as sRGB, which is the only reasonable assumption.
It is a quiet detail, and it is the sort of thing you only notice when it has gone wrong.
Which format to choose
JPG is the safest destination. Every device, every website, and every piece of software made in the last thirty years can open it. Choose it when something has rejected your file and you are not sure why.
PNG is lossless and keeps transparency. It is the right choice for logos, screenshots of text, and diagrams — and the wrong choice for photographs, where it will produce files several times larger than JPG for no visible benefit.
WebP gives roughly 25–35% smaller files than JPG at matching quality and is supported by every current browser. Use it for websites. Avoid it for files you need to email to people, since desktop software support is still patchy.
AVIF compresses better than all of them but takes longer to encode and is not yet universally supported. Your browser may not offer it at all — the dropdown will say so if that is the case.
Common questions
Will converting reduce quality? Converting to PNG will not. Converting to JPG, WebP or AVIF re-encodes the image, which loses a small amount of detail — at 90% quality this is almost never visible. Converting repeatedly between lossy formats does accumulate damage, so convert from the original whenever you can.
Why did my file get bigger when I converted HEIC to JPG? That is expected, and it is not a fault. HEIC is a newer, more efficient format — it stores the same picture in noticeably less space than JPG needs, commonly 30–50% less. Converting to JPG buys you compatibility with Windows and older software, and the price is a larger file. A 900 KB HEIC commonly lands somewhere between 1.3 and 1.8 MB as a JPG, depending on the picture. If size matters more than compatibility, convert to WebP instead, which is closer to HEIC in efficiency.
What happens to transparency? JPG cannot store it, so transparent areas are filled with white. Convert to PNG or WebP if you need to keep them.
Are animated GIFs supported? Only the first frame is converted. Animation is not preserved.
Is there a file size limit? No limit is imposed by us, because we are not paying to process anything. The practical ceiling is your device's available memory.
Coming from an iPhone?
Most people who land here are trying to do one specific thing. These two pages are written for that, with the converter already set to it.
- Convert HEIC to JPG
The same converter, set to JPG, on a page that explains why renaming the file never works and how to stop your iPhone making HEIC at all.
- How to open a HEIC file
For when the question is not how to convert it but why it will not open — and the three ways out, including one that needs nothing installed.
Saved a picture from a website?
WebP is what most sites now serve, and it is the format your browser quietly saved. These two pages are set up for exactly that.
- Convert WebP to JPG
The same converter, set to JPG, on a page that also explains what happens to a transparent background — the part most tools do silently.
- How to open a WEBP file
For when the question is what the file even is. It is not a virus and not damaged; here is where it came from and the three ways to open it.
Common questions
What if my connection drops halfway through? Nothing breaks. The conversion happens on your own device rather than on a server, so a dropped connection cannot interrupt it. The whole site is kept on your device after your first visit, which means you can disconnect entirely and every format on this page still works.
