Are my HEIC files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Why can I not open HEIC files on Windows?

HEIC stores its picture using HEVC, a video codec that Windows does not license by default. Windows 11 offers a paid extension in the Microsoft Store, and it works, but it only fixes your own computer — anyone you send the file to has the same problem. Converting to JPG fixes it once and everywhere.

Does converting HEIC to JPG lose quality?

A little, and less than you would notice. Both formats are lossy, so the picture is compressed twice — once by the phone and once here. At the default quality setting the difference is invisible at normal viewing sizes. If you are converting something you will edit heavily afterwards, raise the quality, or convert to PNG instead and accept a much larger file.

Why is the JPG bigger than the HEIC?

Because HEIC is genuinely better at compression — roughly twice as efficient for the same visual quality. That efficiency is the reason Apple adopted it and the reason nothing else supports it. Expect a JPG around twice the size of the original for a comparable-looking image.

What happens to Live Photos?

A Live Photo is a still image with a short video attached. Only the still is converted, which is what you see in your camera roll and almost always what you want. The video part is not included in the JPG, because JPG cannot hold one.

Does it keep the location and camera information?

No, and that is deliberate. The conversion produces a fresh image from the decoded pixels, so EXIF metadata — GPS coordinates, camera model, the exact timestamp — does not survive it. For a photograph you are about to send to someone, that is usually what you want. If you need the metadata kept, this is not the tool for it.

Can I convert several HEIC files at once?

Yes. Drop a whole batch and each one converts separately, with its own progress. When more than one is finished you can take them as a single ZIP instead of downloading them one at a time.

Are my photos uploaded to a server?

No. The HEIC decoder is downloaded to your device and the photograph is converted there — it never leaves the machine. You can verify it: open your browser's developer tools, switch to the network tab and convert a file, or simply disconnect from the internet and watch the page keep working.

Convert HEIC to JPG

Up to 3 files at once, 100 with Pro. Mixed formats are fine.

HEIC is the format an iPhone saves photographs in, and almost nothing outside Apple can open one; converting HEIC to JPG fixes that everywhere at once. Drop your photos above and they convert on your own device — free, in batches, and without a single byte being uploaded, which for family photographs is the whole point.

Why iPhone photos will not open on Windows

If you have ever emailed a photo from your iPhone to someone on Windows and been told it will not open, you have met HEIC. Apple switched to it in 2017 because it stores the same picture in about half the space of a JPG. The saving is real, and so is the cost: HEIC needs the HEVC video codec, HEVC is covered by a thicket of patents, and most software outside Apple has quietly declined to license it. So the photograph on your phone looks perfect and arrives at its destination as a file nobody can open.

Windows 11 sells an extension in the Microsoft Store that fixes it, and it works — on that one computer. The person you sent the photo to still cannot open it, and neither can the print shop. Converting to JPG fixes the problem at the file rather than at each machine that meets it.

Why JPG is the safe format to send

JPG is thirty years old, entirely unencumbered, and supported by every operating system, every browser, every printer and every form upload ever built. It is the right answer when you do not know what the other end can read — and when you are attaching a photograph to a job application, an insurance claim or a passport form, not knowing is the normal case.

Converting HEIC to JPG without uploading your photos

This conversion runs inside your browser. That is not a performance claim; it is the point. Your photographs are the most personal files you own, and the ordinary way to convert them is to upload them to a website you know nothing about, which keeps them on a server for some period it declines to specify.

Here the decoder is downloaded to your machine and the picture never moves. You can watch this happen: open your browser's developer tools, switch to the network tab, and convert a file. Nothing is sent. The page works with your network disconnected, which is the only proof that really settles the question.

What you lose: size, metadata and a little quality

Both formats are lossy, so the image is compressed a second time, and at the default setting the result is visually indistinguishable from the original at any normal size. The file will be larger — roughly twice — because that compression advantage was the whole reason for HEIC.

And the metadata goes: GPS coordinates, camera model, the precise timestamp. For a photograph you are about to send to a stranger, stripping the location out is a feature rather than a loss, but if you are archiving rather than sharing, keep the original alongside the JPG.

Converting a whole camera roll at once

Drop as many files as you like. Each converts on its own with its own progress, and once more than one is finished you can take the lot as a single ZIP rather than clicking through downloads. Because the work happens on your device, a batch is limited by your machine rather than by a queue or a daily allowance — in our measurements a single HEIC photo takes under a second.

If quality matters more than convenience, the settings under the result let you raise it. If the picture is a screenshot or a scan rather than a photograph, convert it to PNG instead — JPG compression is built for continuous tone and makes a visible mess of sharp edges.

How to convert HEIC to JPG on Windows, Mac or your phone

Drop your HEIC file onto this page, or click to choose one. A whole batch works too.
The conversion starts on its own, in your browser. Nothing is uploaded.
Download the JPG — or take the whole batch as a ZIP.

HEIC vs JPG: what an iPhone photo gains and loses

HEIC compared with JPG
	HEIC	JPG
Full name	High Efficiency Image Container	JPEG Image
File extension	.heic	.jpg, .jpeg, .jpe
Media type	image/heic	image/jpeg
Compression	Lossy — file size is bought with quality	Lossy — file size is bought with quality

Quality: Some quality is given up for a smaller file. At the default setting the difference is hard to see.
Where it runs: This conversion runs inside your browser. Your file is never uploaded, and it works with the network disconnected.
