How to convert HEIC to JPG for free

A short, practical guide.

If you have ever taken a photo on an iPhone and then tried to upload it somewhere, a website form, an old computer, a friend's Android phone, and gotten an error or a file that will not open, HEIC is almost always the reason.

What is a HEIC file, and why does it cause problems?

HEIC (High Efficiency Image Container) is the photo format Apple switched to by default a few years ago. It stores photos at roughly half the file size of a JPG with similar quality, which is genuinely useful for saving storage space on a phone.

The problem is support outside Apple's own ecosystem. Plenty of websites, older software, some Android phones, and many workplace systems still do not recognize HEIC at all. You end up with a photo that looks fine in your camera roll but fails to upload or shows as broken everywhere else.

The simplest fix: convert to JPG

JPG is supported absolutely everywhere, every browser, every operating system, every upload form built in the last twenty years. Converting a HEIC photo to JPG once solves the compatibility problem permanently for that file.

How to convert HEIC to JPG online, free

1. Open the image format converter on TidyToolbox.
2. Drop in your HEIC photo, or a whole batch of them at once.
3. Choose JPG as the output format.
4. Download the converted file, or all of them as a ZIP if you added more than one.

The conversion happens directly in your browser. Nothing is uploaded to a server, which matters if the photos are personal.

A couple of things worth knowing

You can change your iPhone to save new photos as JPG automatically instead of HEIC, in Settings, Camera, Formats, and choosing "Most Compatible." This does not fix photos you already have, but it prevents the problem going forward if compatibility matters more to you than saving storage space.

Converting to JPG does involve a small amount of compression, since JPG is a lossy format. For everyday photos this is not noticeable. If you need a fully lossless result, converting to PNG instead is an option, though the file size will be larger than the original HEIC.
