How to Convert iPhone HEIC Photos to JPG on Windows (No App)

The short answer

Yes. You can convert iPhone HEIC photos to JPG on a Windows PC without installing an app. Copy the photos to the computer (cable, AirDrop to a Mac then USB, email to yourself, or a USB stick), open a HEIC to JPG tool in the browser, choose the files, and download JPGs. The conversion can run in that tab. The pictures do not have to be uploaded to a random website.

HEIC is Apple’s default for Camera on recent iPhones. It is smaller than JPG at similar quality. That is good on the phone. It is bad on Windows, where File Explorer often shows a blank icon, and on websites that only accept .jpg or .png.

Microsoft does offer a HEIF extension in the Microsoft Store. It helps preview files. It does not help you send a JPG to a job portal, a landlord, or WhatsApp Web. For sharing, you still want JPG.

Why Windows will not open the iPhone photo

You plugged the phone in, copied DCIM, and double-clicked a file named IMG_1234.HEIC. Nothing useful happens. Or you emailed the photo to yourself and Gmail shows a download you cannot preview. That is HEIC, not a broken cable.

Apple stores High Efficiency Image Container files. Windows 10 and 11 do not treat them like JPG unless extra codecs are installed. Older office PCs, school machines, and locked-down work laptops will not let you install those codecs. A browser converter avoids that fight.

Some email apps silently fail: they attach the HEIC, the other person is on Outlook for Windows, and they see an empty attachment. Converting first is less painful than explaining codecs to your manager.

What “no app” and “no upload” mean here

“No app” means you should not need CopyTrans, iMazing, or a $30 converter just to open a birthday photo. A website that runs the decoder in JavaScript is enough for ordinary snapshots.

“No upload” means the HEIC is decoded in your browser. The JPG is built there and saved to Downloads. If the site asked you to drop a file and then showed a cloud progress bar, that was an upload. Fine for a meme. Poor for passport photos, kids, or anything from a workplace.

ReetInfoTech’s HEIC to JPG tool decodes on your device. There is no account. There is no watermark. You can select more than one file.

Convert HEIC to JPG in the browser

Get the HEIC files onto the PC first. The converter cannot reach into the iPhone by itself — your browser can only read files you choose.

1. Copy the photos to Windows. USB cable and File Explorer is the usual path: iPhone → DCIM → copy the HEIC files to a folder. You can also email them to yourself, use OneDrive/Google Drive, or AirDrop to a Mac and move them on a stick. WhatsApp from iPhone to a PC often already sends JPG — if the file is already .jpg, you are done.
2. Open HEIC to JPG on this site. Go to Tools, then HEIC to JPG. You should see a note that nothing is uploaded. If you do not, you are on the wrong page.
3. Choose one or more HEIC or HEIF files. Shift-click to select a batch. Live Photos are still a still image plus a short video; this tool converts the still. Burst shots are separate files — pick the ones you need.
4. Set JPG quality, then convert. 85% is a sensible default for email and WhatsApp. 95% is for prints or a portfolio. 60% is only for tiny previews. Convert, then open one JPG at full size. If skin or sky looks blotchy, raise quality and convert that photo again.
5. Save and send the JPGs. Downloads will contain .jpg files. Attach those. Do not send the original .heic “just in case” unless you know the other person is on an iPhone.

Large batches can make a laptop fan spin. That is the decoder working on your CPU, which is the point: the photos stayed local. Let the tab finish. Do not close it mid-batch.

Email, WhatsApp, and job portals

Gmail is happier with JPG. Many application forms only accept .jpg or .png. A HEIC upload fails with a useless “invalid file” error. Convert first.

WhatsApp Web on Windows will send a JPG as an image. A HEIC sometimes goes as a generic document the other person cannot swipe through. If you already share from the iPhone app, WhatsApp may convert for you. The problem is almost always the PC path.

For a portal that also caps file size, convert to JPG, then compress if needed. A 12 MP iPhone shot as high-quality JPG is often 2–4 MB — fine for email, sometimes large for a 1 MB form. In that case, convert at a slightly lower quality rather than screenshotting the photo.

Stop creating HEIC next time (optional)

On the iPhone: Settings → Camera → Formats. Most Compatible saves JPG (and H.264 video). High Efficiency saves HEIC. Most Compatible uses more storage. That is the trade.

You do not have to switch forever. Keep High Efficiency for everyday camera use, and convert only the photos you send to Windows people. Switching the whole camera to JPG is worth it if you constantly move photos to a work PC.

When you still want an app

A desktop app is better if you convert thousands of photos every week, or you need RAW alongside HEIC. For a dozen holiday pictures, the browser is enough. Do not pay a subscription to open a file Apple named with four letters.
