How to Convert HEIC to JPG on Windows 11 (Free, Without Uploading)

If you want to convert HEIC to JPG on Windows, you have probably just discovered that your iPhone photos will not open on your PC. You copy a batch of photos from your iPhone to your Windows 11 laptop, double-click one, and Windows Photos shows an error instead of your picture. The good news is that fixing this takes less than a minute, and every method below is free.

In this guide you will learn what HEIC actually is, why Windows refuses to open it, and five free ways to convert HEIC to JPG — including a converter that runs entirely in your browser so your photos are never uploaded anywhere.

What is HEIC, and why won't Windows open it?

HEIC (High Efficiency Image Container) has been the default photo format on iPhones since iOS 11, released in 2017. Apple switched to it because it stores photos at roughly half the file size of a JPG with the same visual quality, which saves a lot of storage on your phone.

The catch is compatibility. HEIC photos are compressed with the HEVC video codec, and Windows does not include the HEVC decoder out of the box — Microsoft sells it as a small paid add-on. That is why a file named photo.heic opens perfectly on your iPhone and your Mac, but does nothing on a Windows PC. Many websites, job-application forms, and older programs also reject HEIC uploads, so converting to JPG is often the only practical fix.

One important warning: simply renaming photo.heic to photo.jpg does not convert the file. It is still HEIC data inside, and most apps will refuse it or show an error. You need a real conversion, which re-encodes the image data as a genuine JPEG.

Method 1: Convert HEIC to JPG in your browser — no upload, no install (fastest)

The quickest way to convert a few photos is a browser-based converter. But there is a privacy catch with most of them: they upload your photos to someone else's server first. If your photos contain people, documents, or location data, that trade-off is worth avoiding.

That is why we built our free HEIC to JPG converter: it runs entirely inside your browser tab using WebAssembly. The page loads a decoder compiled to WASM, your files are processed in memory on your own machine, and nothing is ever uploaded. You can even disconnect from the internet after the page loads and it still works.

To convert HEIC to JPG without uploading:

  1. Open the HEIC to JPG converter in Chrome or Edge on your Windows PC.
  2. Drag your .heic files onto the page — converting several at once works.
  3. Choose JPG output and your quality setting, then click Convert Now.
  4. Download each JPG. Done — no account, no watermark, no upload.

Because the files never leave your PC, this gives you the privacy of a desktop app with the convenience of a website. If the resulting JPGs are still too large for an upload form, you can then shrink them with our free photo resizer, which targets an exact file size like 20KB or 50KB.

Method 2: Install the free codec and use the Photos app

If you would rather open HEIC files directly on your PC, Windows can learn to read them with two add-ons from the Microsoft Store:

  1. Open the Microsoft Store and install HEIF Image Extensions — this one is free.
  2. Also install HEVC Video Extensions. Microsoft charges $0.99 for the standard version, but there is a free edition called HEVC Video Extensions from Device Manufacturer — search for that exact name.
  3. Double-click any HEIC file. It should now open in the Photos app, and thumbnails will appear in File Explorer.

To convert, open the photo in the Photos app, click the See more (three dots) menu, choose Save as, and pick .jpg as the file type. This saves a new JPG and leaves your original HEIC untouched. This method is fine for one photo at a time, but it gets tedious for a whole holiday album.

Method 3: Stop your iPhone saving photos as HEIC in the first place

If you regularly move photos to a Windows PC, the simplest long-term fix is to make your iPhone capture JPGs:

  1. On your iPhone, go to Settings > Camera > Formats.
  2. Switch from High Efficiency to Most Compatible.

New photos will now be saved as JPG. Note that JPGs take up roughly twice the storage space of HEIC, so this is a trade-off if your phone storage is tight.

There is also a middle setting worth knowing: Settings > Photos > Transfer to Mac or PC > Automatic. With this on, your iPhone automatically converts HEIC photos to JPG when you copy them to a Windows PC over USB — you keep the storage savings on the phone and get compatible files on the computer.

Method 4: Batch-convert hundreds of photos with a free desktop app

For large batches — say, 400 photos from a weekend trip — a dedicated desktop converter is the most efficient option:

  • iMazing HEIC Converter (Windows and Mac, free): drag in hundreds of files, choose JPG or PNG, and convert in one go. It preserves EXIF metadata such as the date and GPS location.
  • CopyTrans HEIC for Windows (free): adds a right-click Convert to JPEG option in File Explorer, which is handy for quick batches.
  • IrfanView (free, with the plugin pack): open a HEIC file and use File > Batch Conversion to process whole folders.

All three work fully offline and cost nothing, which makes them a good fit if you convert photos regularly.

Which method should you use?

  • A few photos, right now: use the no-upload browser converter — fastest, private, nothing to install.
  • You just want to view HEIC on your own PC: install the two Store extensions from Method 2.
  • Hundreds of photos: use iMazing or CopyTrans from Method 4.
  • You are tired of the problem entirely: switch your iPhone to Most Compatible (Method 3).
  • Sensitive or personal photos: avoid upload-based online converters; use the browser converter, a desktop app, or the codec method instead.

Frequently asked questions

Is it free to convert HEIC to JPG?

Yes. Every method in this guide is free, including the browser converter, the Microsoft Store codec route (using the free HEVC edition), and the desktop apps. You should never need to pay to convert HEIC to JPG.

Does converting HEIC to JPG lose quality?

A high-quality JPG conversion is visually identical to the original for normal viewing and printing. HEIC is technically more efficient, so the JPG file will be larger, but at 90%+ quality you will not see a difference. If you need a pixel-perfect copy, choose PNG output instead.

Why are my iPhone photos HEIC instead of JPG?

Apple made HEIC the default camera format in iOS 11 (2017) because it halves file sizes at the same quality. Your iPhone has been saving HEIC all along — you only notice when you move the files to Windows.

Is it safe to upload HEIC photos to online converters?

It depends on the photos. Uploading means a copy of your image sits on someone else's server, even briefly. For family photos, IDs, or anything with location data in the EXIF, prefer a method where files never leave your device — a browser converter that runs locally, a desktop app, or the Windows codec method.

How do I stop my iPhone from saving HEIC photos?

Go to Settings > Camera > Formats and choose Most Compatible. Alternatively, keep HEIC on the phone but enable Settings > Photos > Transfer to Mac or PC > Automatic, so photos are converted to JPG automatically when copied to a Windows PC.

The bottom line

HEIC is a better format trapped in a compatibility gap, and JPG remains the universal language for photos in the meantime. For most people, the fastest fix is converting in the browser without uploading — try our free HEIC to JPG converter and your photos will be Windows-ready in seconds. And if your converted JPGs need to fit a strict file-size limit afterwards, our exact-KB photo resizer handles that too.
