Convert HEIC to JPG

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.

JPG is thirty-four years old, entirely unencumbered, and read by every operating system, every browser and effectively every printer and upload form you will meet. 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.

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.

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.

Drop up to 100 files at once. 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 waits on your machine rather than on a queue or a daily allowance — in our measurements a single HEIC photo takes under a second. A camera roll larger than a hundred has to go through in more than one drop.

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.

iPhones can be told to photograph in JPG directly, under Settings, Camera, Formats — the option is called Most Compatible. It roughly doubles the space each picture takes and removes the problem at the source, which is the right trade for anyone who sends photographs more often than they run out of storage.

Leaving the camera on HEIC and converting when you need to is the other reasonable answer, and it is the one this page exists for. What is not reasonable is emailing a HEIC to someone on Windows and waiting to hear that it did not open.
