Convert HEIC to JPG on Windows Without Installing Anything

Why won't my HEIC photos open on Windows?

Since iOS 11, iPhones save photos as HEIC (High Efficiency Image Container) by default. It's a smart format — it keeps the same quality as a JPG at roughly half the file size, which is why your phone's storage lasts longer. The catch is that older versions of Windows, most web browsers, and a lot of everyday apps still expect a plain JPG. So the moment you move an iPhone photo to a PC, it can feel like it's locked.

You have two real options: install Microsoft's free HEIC codec so Windows can read the file, or skip all of that and convert the photo to JPG. For most people, converting is faster and avoids the codec hassle entirely.

Method 1: Convert HEIC to JPG online (fastest, no install)

This is the method I reach for on a PC that isn't mine — a library computer, a work laptop with locked-down software, or a friend's machine. Everything happens in the browser, so there's nothing to download.

1. Open the HEIC to JPG converter on this page.
2. Drag your .heic files in, or click to browse and select them.
3. Wait a second or two while each photo is converted to JPG.
4. Click Download — grab one file, or all of them as a zip.

Because the conversion runs in your browser, it works exactly the same on Windows 10 and Windows 11, and you don't need administrator rights. If you also need a different format later, the same workflow covers PNG to JPG and JPG to PNG.

Method 2: Convert with the built-in Windows Photos app

If the photos are already on your PC and you'd rather use what's built in, the Windows Photos app can save a HEIC as a JPG — once Windows can read HEIC in the first place.

Step 1: Add the free HEIF codec (one time)

Open the Microsoft Store and install HEIF Image Extensions. It's a free, official add-on from Microsoft that teaches Windows how to open .heic files. You can read Microsoft's own notes in the Windows support documentation.

Step 2: Save the photo as JPG

1. Double-click the .heic file so it opens in Photos.
2. Click the three-dot menu in the top-right corner.
3. Choose Save as.
4. In the Save as type dropdown, pick JPG, then save.

This is fine for one or two photos. For a full camera roll, it gets tedious fast — which is where the next method helps.

Method 3: Convert a whole folder of HEIC photos at once

Vacation albums and event photos usually come in batches, not singles. To convert many files in one go, select all of your .heic files together and drop them into the converter above in a single batch. Every photo is processed, and you download the finished JPGs as one zip. If those JPGs end up too large to email or upload, run them through image compression afterward to shrink the size without a visible drop in quality.

Will I lose quality or photo details?

Converting HEIC to JPG is a small, practical trade-off. JPG is slightly less efficient than HEIC, so the file may be a little larger, but at high quality the difference is invisible to the eye. Most photo metadata — the date and basic camera info — carries over. If you rely on GPS location tags for every shot, keep your original .heic files as a backup before converting.

Which method should you use?

• Need it done now, or on a PC you don't control? Use the online converter (Method 1).
• Prefer built-in Windows tools and only have a couple of photos? Use Photos (Method 2).
• Converting an entire folder? Batch-convert online (Method 3).
