How to Convert HEIC Photos to JPG on Windows
Published August 6, 2026
You copy a folder of photos off an iPhone, open it on your PC, and every thumbnail is blank. Or you try to attach one to an email and the site refuses it. The culprit is a file extension you probably never chose: .heic. This guide explains what HEIC actually is, why Windows and most websites trip over it, and how to turn those photos into ordinary JPG files in a few seconds — without installing anything and without uploading your pictures to a stranger's server.

HEIC stands for High Efficiency Image Container. It's the format Apple switched to as the iPhone default back in iOS 11, and every iPhone since has been quietly saving your photos this way unless you changed a setting.
The reason Apple made the switch is genuinely good: HEIC uses a modern compression method (HEVC, the same family used for 4K video) and stores the same photo in roughly half the space of a JPG at comparable quality. On a phone where storage is finite and you take 3,000 pictures a year, halving the size of every one of them is a big win. HEIC can also hold extras a JPG can't — a depth map for Portrait mode, multiple frames for Live Photos, and 16-bit colour instead of 8-bit.
The problem isn't the format. The problem is everything else: JPG has been universally supported for thirty years, and HEIC has not.
Why won't Windows open HEIC photos?
On many Windows PCs, HEIC files simply don't render. You'll see one of these symptoms:
- Blank or generic thumbnails in File Explorer instead of picture previews.
- An error in the Photos app along the lines of "this file format is not supported."
- A website, forum, or job application form rejecting the upload because it only accepts .jpg and .png.
- An older program — Photoshop CS6, an ancient printing utility, your accountant's expense portal — that has never heard of HEIC.
The technical reason is licensing. HEVC decoding requires patent-licensed codecs, so Microsoft can't bundle them freely with every Windows edition the way it does JPG and PNG support. Some machines ship with the codec preinstalled by the manufacturer; many don't. Windows will offer to install "HEVC Video Extensions" from the Microsoft Store, but the version that reliably works has historically been a paid item, and codec installs can behave differently across builds and OEM images.
That's why converting is usually the faster answer. A JPG works everywhere, forever, with zero setup — on Windows, Android, Linux, in every browser, in every upload form, and in every old program you own.
How to convert HEIC to JPG in Toolyard
The Toolyard HEIC to JPG Converter is free, requires no account, and does the whole job inside your browser — your photos are never uploaded anywhere. Here's the full process:
- Get the photos onto your PC first — by USB cable, AirDrop to a Mac then a shared folder, iCloud for Windows, or a download from iCloud.com. They'll arrive as
.heic(occasionally.heif) files. - Open the HEIC to JPG Converter and drag your files onto the drop zone, or click browse files. You can select a whole batch at once.
- Choose your output format: JPEG — opens everywhere is the right answer for sharing and uploading. Pick PNG — lossless only if you need a perfectly lossless copy for editing (expect a much bigger file).
- Set the Quality slider. Around 90% is the sweet spot: visually identical to the original for normal viewing, with a sensible file size. Push it to 100% only for photos you'll print large.
- Each photo converts and appears with a preview. Click Download on an individual file, or hit Download all to grab the entire batch in one go.
Because the conversion runs on your own device, there's no upload wait and no queue — a folder of holiday photos converts about as fast as your PC can chew through them, and it keeps working even if your connection drops after the page has loaded.
Will I lose quality?
A little, in the strict technical sense — and almost certainly not in any way you'll see. Both HEIC and JPG are lossy formats, so re-encoding means the picture is compressed a second time. At a high quality setting the difference is invisible on a screen and invisible in a print.
What will change noticeably is the file size, and in the direction people don't expect: your JPG will usually be bigger than the HEIC original, often close to double. That's not a bug — it's the whole reason Apple moved to HEIC. You're trading storage efficiency for universal compatibility.
Two things do get dropped in the conversion, and it's worth knowing about them:
- Live Photo motion. A HEIC that's half of a Live Photo becomes a single still frame. The short video lives in a separate file on the phone.
- Depth data. Portrait-mode depth maps don't survive as JPG, so you can't re-edit the background blur afterwards. Convert a copy and keep the originals if that matters to you.
If the resulting JPGs are too heavy to email or upload, don't lower the quality until the photo looks bad — shrink them properly instead:
JPGs came out too big?
Compress your converted photos down to a size that will actually attach to an email — with a live preview so you can see exactly what you're giving up.
Open the Image Compressor →Should you just turn HEIC off on your iPhone?
You can, and for some people it's the right call. On the iPhone go to Settings → Camera → Formats and choose Most Compatible instead of High Efficiency. From then on the camera saves JPG, and this whole problem disappears for future photos.
The trade-off is storage: every new photo takes roughly twice the space, on a phone and in your iCloud allowance. There's also a related setting worth knowing — Settings → Photos → Transfer to Mac or PC → Automatic tells the iPhone to hand over JPG copies when you plug into a computer, while keeping HEIC on the device.
Most people land in the middle: leave the iPhone on High Efficiency to save space, and convert the handful of photos that actually need to go somewhere else. That's a five-second job, not a settings change.
A word about privacy
Photos are personal, and a HEIC straight off a phone carries more than the picture. Buried in its metadata are the GPS coordinates of where it was taken, the exact date and time, and your phone model. Uploading a family album to an anonymous "free converter" website to get JPGs back means handing all of that to someone whose business model you don't know.
That's the core reason Toolyard works the way it does. The HEIC decoder is a small library that loads into the page and runs on your machine — the file is read from your disk by your own browser, converted there, and saved back. No upload happens at any point.
If you're about to post the converted photos publicly, it's worth stripping the location data too. Our guide on removing EXIF and GPS data from photos covers what's hidden inside and how to clear it.
Is it private and free?
Yes to both. The Toolyard converter is 100% private because it decodes your HEIC files and writes the JPGs entirely inside your browser — your photos are never uploaded to any server. It's completely free with no sign-up, no file limit and no watermark, and once the page has loaded you can convert offline.
FAQ
What is a HEIC file?
HEIC is the photo format iPhones have used by default since iOS 11. It stores the same picture as a JPG at roughly half the file size by using a newer compression method (HEVC). The downside is that many programs and websites still can't open it.
Why won't my HEIC photos open on Windows?
Windows doesn't include HEIC support out of the box on every edition. Without the HEVC codec installed, Photos and File Explorer show a blank thumbnail or an error. Converting to JPG avoids the problem entirely.
Does converting HEIC to JPG lose quality?
There's a small loss because both formats are lossy, but at a high quality setting the difference is invisible on screen or in print. The JPG will usually be larger than the HEIC original, since JPG compresses less efficiently.
Can I convert several HEIC photos at once?
Yes. The converter accepts a whole batch of .heic files at once and gives you a "Download all" button, so you don't have to repeat the process for every photo.
Is converting HEIC files online safe?
With Toolyard, yes. The decoding and conversion happen entirely inside your browser, so your photos are never uploaded to a server and nothing leaves your device.
Should I just stop my iPhone shooting HEIC?
You can — in Settings → Camera → Formats, choose "Most Compatible" and your iPhone will shoot JPG instead. You'll use roughly twice the storage per photo, so many people keep HEIC and convert only the pictures they need to share.
