How to Convert HEIC to JPG (Free, On Any Device)

You took a perfectly good photo, tried to upload it to a job application, a listing site, or a school portal, and the form spat it back. Or you copied it to a Windows PC and got a broken thumbnail and a shrug. The photo is fine. The format is the problem: your iPhone saved it as HEIC, and a surprising amount of the world still refuses to open one. This guide covers every honest way to get a JPG or PNG out of it, including the routes that need no install at all, and ends with the setting that stops the problem at the source if you are tired of fighting it.

What HEIC actually is (and why Apple uses it)

HEIC is Apple's flavor of HEIF, a modern image container that compresses photos far more efficiently than JPG. iPhones have shot it by default since iOS 11 back in 2017. And credit where due: it is genuinely good. A HEIC file is roughly half the size of an equivalent JPG with no visible quality loss, which is why your phone storage lasts as long as it does.

The catch is purely compatibility. JPG has had thirty years to become the universal language of photos; HEIC has not. Web forms, older software, many printers, most non-Apple devices, and plenty of Windows machines either reject it outright or need extra codecs to read it. So the goal is rarely "get rid of HEIC forever." It is "get this one photo into a format the thing in front of me accepts."

Pick your route

Your situation	Best route
One photo, any device, right now	Browser converter (below)
You are holding the iPhone	The built-in tricks (share via Mail, or copy and paste into Files)
Photos arrive broken on your Windows PC	Set the iPhone to convert during transfer, or convert in the browser
You are on a Mac	Preview's Export does it natively
Sick of the problem entirely	Switch the camera to Most Compatible (last section)

Route 1: convert in the browser (works everywhere)

The fastest fix when a form just rejected your photo, because it works on whatever machine you are sitting at, including the PC that cannot open HEIC in the first place. The file does not need to be openable locally to be uploadable.

1. Open the converter. Go to ButterySpace's Convert Format tool. It runs in the browser, so it works the same on Windows, Mac, Linux, or a Chromebook, with no install and no sign-in.
2. Drop your photo. Drag the HEIC file in or click to browse. Files up to 20 MB are fine, which covers any iPhone photo with room to spare.
3. Pick the output. Choose JPG for the smallest widely accepted file, or PNG for a lossless re-encode. JPG quality is adjustable and defaults to 90.
4. Convert and download. Hit Convert image and download the result. The photo's orientation is preserved, so portraits stay upright instead of arriving sideways.

A conversion costs 1 pat of the 5 free ones you get each day, so a handful of photos a day costs nothing. It also reads AVIF, TIFF, and BMP if some other awkward format is the one in your way, and it can write WebP, TIFF, BMP, or GIF when a JPG is not what the destination wants. Uploads auto-delete within 24 hours.

Route 2: on the iPhone itself

If the phone is in your hand, iOS will quietly convert for you in a few places:

• Share it by Mail. Emailing a photo from the Photos app sends a JPG, not the HEIC. Mailing a photo to yourself is the oldest trick in the book and still works.
• Copy it into Files. In Photos, select the photo and tap Copy Photo, then open the Files app and paste into any folder. On current iOS versions the pasted copy lands as a JPG. Quietly one of the most useful behaviors Apple never advertises.
• Convert during transfer. In Settings, go to Photos and set Transfer to Mac or PC to Automatic. Photos then convert to a compatible format whenever you copy them off over a cable, which is the clean fix if your Windows machine is where HEIC keeps biting you.

Route 3: on Windows

Windows can learn to open HEIC, but it does not always come willingly. Recent Windows 11 builds handle many HEIC files out of the box; older installs need the HEIF Image Extensions from the Microsoft Store, and the underlying HEVC codec that actually decodes the image data has historically been a paid extra. If the Photos app opens your file, File Explorer's right-click menu or the Photos app's save options can re-save it as JPG or PNG.

Honestly though, if you are reading this on the Windows machine that cannot open the photo, the browser route above is faster than untangling codec packs, and it does not care what Windows thinks of the file.

Route 4: on a Mac

Macs read HEIC natively, so this one is easy. Open the photo in Preview, choose File, then Export, and pick JPEG or PNG as the format. The Photos app does the same via File, Export. No extra software, no tricks.

Should you stop shooting HEIC?

If the format fights you constantly, you can make the iPhone shoot JPG directly: in Settings, go to Camera, then Formats, and choose Most Compatible instead of High Efficiency. New photos save as JPG from then on.

Our honest take: most people should not flip it. HEIC's storage savings are real, JPG files quietly double the space your camera roll eats, and the compatibility problem only surfaces for the occasional photo that leaves the Apple bubble. Converting on demand keeps the best of both. Flip the setting only if your photos routinely head somewhere HEIC cannot follow, like a Windows-based workflow or a system that ingests photos automatically.

A note for makers

If the reason you are converting is a craft or print project, the format wall shows up there too: image tools, including ButterySpace's own Lithophane, 3D Bookmark, and Color Book, take PNG, JPG, or WebP, not HEIC. Convert the photo first and the rest of the pipeline butters itself. For the full phone-to-printed-lithophane walkthrough, see how to make a lithophane from an iPhone photo.
