How to Convert HEIC to JPG Free on Windows and Mac
iPhone photos default to HEIC since iOS 11, 50% smaller than JPEG but only Safari opens them. Free methods to convert HEIC to JPG on Windows, Mac, and online.
Your iPhone has been silently saving photos in HEIC format since iOS 11 launched in September 2017. In 2025, there are 1.56 billion active iPhone users worldwide (DemandSage, 2026), and every one of them hits the same wall sooner or later: you share a photo on Windows, try uploading to a website, or send it to an Android friend, and they can't open it.
The reason is simple. Only Safari supports HEIC natively in a web browser. Chrome, Firefox, and Edge don't. Most social media platforms reject HEIC uploads. Windows can't even open the file without an optional codec that isn't installed by default. This guide covers five free methods to fix that, across every platform, with no software purchase required.
Key Takeaways
- As of 2026, 1.56 billion iPhones shoot HEIC by default (DemandSage), but only Safari opens it natively in a browser.
- HEIC files are roughly 50% smaller than equivalent JPEGs at the same quality (Cloudinary, 2024), which is why Apple chose it as the default.
- Windows requires a free codec from the Microsoft Store before it can open or convert HEIC files.
- Mac users can convert instantly using Preview or Finder Quick Actions, with no downloads needed.
- Prevent future HEIC files entirely: Settings > Camera > Formats > Most Compatible on your iPhone.
What Is HEIC and Why Won't Windows Open It?
In September 2017, Apple introduced HEIC as the default iPhone camera format with iOS 11, starting with the iPhone 7. According to Cloudinary's 2024 image format guide, HEIC files are approximately 50% smaller than equivalent-quality JPEG files. A 12-megapixel iPhone photo runs roughly 3.5 MB as a JPEG, 2.1 MB as WebP, and just 1.8 MB as HEIC (LetsConvert, 2024). That difference across an entire photo library adds up to gigabytes of saved storage space.
The format is based on HEIF (High Efficiency Image File Format), a container standard developed by MPEG. HEIC and HEIF are often used interchangeably. Technically, HEIF is the open standard and HEIC is Apple's implementation of it, identified by the .heic or .heif file extension on your device.
The compatibility problem goes wide. As of November 2025, only Safari natively supports HEIC in a web browser (Wikipedia, HEIF article, 2025). Chrome, Firefox, Edge, and Opera can't display HEIC images without a plugin. Facebook, Instagram, and Twitter/X reject HEIC uploads. On Windows, the operating system needs the optional HEIF Image Extensions codec, downloaded from the Microsoft Store, before any HEIC file can be opened (Windows Central, 2024). That codec isn't installed by default. It's the reason most Windows users see a black screen or an error the first time a friend sends them an iPhone photo.
How to Convert HEIC to JPG on Windows (2 Free Methods)
Windows 10 version 1809 and later, along with Windows 11, can handle HEIC conversion for free. You have two paths: the built-in Photos app after a one-time codec install, or IrfanView, a free third-party viewer that needs no Microsoft Store account. Both options work well for single files and batch conversions.
Method 1: Windows Photos App with the HEIF Codec
- Get the codec: Open the Microsoft Store and search for HEIF Image Extensions. Click Get. It's free and installs in about a minute. Skipping this step is the single most common reason users hit a blank screen when opening a .heic file in Photos.
- Open the photo: Double-click any .heic file. It should now open in Windows Photos instead of showing an error.
- Save as JPEG: Click the three-dot menu at the top right and choose Save a copy. In the Save As dialog, change the file type to JPEG.
- Bulk convert: Select multiple .heic files in File Explorer, right-click, and choose Open with > Photos. Then use Save a copy on each file in turn.
Method 2: IrfanView (No Microsoft Store Needed)
IrfanView is a free, lightweight image viewer that handles HEIC without requiring a Microsoft account or Store access. It's a practical choice for work computers or shared machines.
- Download IrfanView from irfanview.com (free, no subscription).
- During installation, also download the All Plugins package when prompted. That package is what adds HEIC support.
- Open your .heic file with IrfanView, then go to File > Save As and choose JPEG from the format dropdown.
- For batch conversion: go to File > Batch Conversion/Rename, add your HEIC files, set output format to JPEG, and click Start Batch. All files convert in one pass.
How to Convert HEIC to JPG on Mac (No Downloads Required)
Apple introduced HEIC format in iOS 11 and added native HEIC support to macOS High Sierra in September 2017 at the same time. Every Mac running High Sierra or later can open, preview, and convert HEIC files without installing anything. Three built-in methods cover single files, quick bulk conversions, and automated recurring workflows.
Method 1: Preview App (Single File or Batch)
- Double-click any .heic file to open it in Preview, or right-click and choose Open With > Preview.
- Go to File > Export.
- In the Format dropdown, select JPEG.
- Adjust Quality if needed. The default is high quality, which is fine for most uses.
- Batch convert: Select multiple .heic files in Finder, right-click, and choose Open With > Preview. All files load as thumbnails in the sidebar. Go to Edit > Select All, then File > Export Selected Images, choose JPEG as the format, pick an output folder, and Preview converts everything at once.
Method 2: Finder Quick Actions (macOS Monterey and Later)
This is the fastest bulk method available. It's built into Finder, so there are no menus to dig through.
- Select one or more .heic files in Finder.
- Right-click (or Control-click) and look for Quick Actions in the menu.
- Choose Convert Image.
- Select JPEG as the format. Converted files appear in the same folder immediately.
If Convert Image is missing from Quick Actions, go to System Settings > Privacy & Security > Extensions > Finder and enable Convert Image.
Method 3: Automator (For Recurring Batch Conversions)
If you regularly receive HEIC files from colleagues or clients, Automator can build a right-click workflow that converts any selected files to JPEG automatically. The setup takes about five minutes. Once created, the workflow appears in Quick Actions for any HEIC file going forward. Search "Automator convert image HEIC to JPEG" along with your macOS version for the exact steps, since the Automator interface varies between OS releases.
How to Convert HEIC to JPG Free Online
Online converters are the fastest option when you're on a borrowed machine, a Chromebook, or simply don't want to install anything. Most are free and require no account. Popular options include heic2jpg.com and ilovimg.com. Both convert single or multiple files in seconds with no sign-up for standard use.
The tradeoff is that your file uploads to a third-party server. For photos of landscapes, food, or everyday objects, that's perfectly fine. For photos that might contain GPS coordinates, timestamps, or recognizable people, uploading to an unknown server carries a privacy risk that most converter sites don't explain clearly. "We delete files after one hour" is a policy statement. It isn't an architectural guarantee that the file never persists anywhere.
For anything private, convert locally using Preview on Mac or Windows Photos. If your photos contain location data from home, work, or personal events, ZerofyTools' File Privacy Scanner strips GPS and other EXIF metadata entirely in your browser, with no upload required.
Once your photos are in JPG format, you can also convert between JPG, PNG, and WebP in the browser if you need a different format for web use or a specific platform's requirements. Everything runs locally, nothing leaves your device.
How to Stop Your iPhone from Shooting HEIC (Permanent Fix)
If you share photos with Windows users regularly, switching your iPhone to save JPEGs from the start eliminates the conversion step entirely. Apple provides a setting for this, but it's buried two levels deep in Camera settings and most users never find it.
Go to Settings > Camera > Formats on your iPhone. You'll see two options:
- High Efficiency: Saves photos as HEIC. Files are roughly 50% smaller than JPEG. Best for keeping more photos on your device without running out of storage.
- Most Compatible: Saves photos as JPEG. Files are larger but open on every device, browser, and platform without any conversion step.
Select Most Compatible. From that point on, your camera saves every new photo as a JPEG. Existing HEIC photos on your device aren't affected by this change.
The tradeoff is storage space. JPEGs run roughly twice the file size of equivalent HEIC photos, so your available storage fills up faster. If you have a 256 GB iPhone with plenty of room to spare, Most Compatible is the right default. If storage is tight, stick with High Efficiency and convert only when you need to share a specific photo.
One behavior worth knowing: when you share a HEIC photo via AirDrop to a Mac, iOS automatically converts it to JPEG during the transfer. This happens silently. The Mac receives a .jpg file even though the original on your phone is .heic. This conversion applies only to AirDrop transfers to Mac. Photos transferred to Windows via USB cable, iCloud sync, or email arrive as raw .heic files and still need conversion on the Windows side.
Frequently Asked Questions
What is the difference between HEIC and HEIF?
HEIF (High Efficiency Image File Format) is the container standard developed by MPEG and approved by ISO. HEIC is Apple's specific implementation of HEIF, used on iPhone and iPad devices with the .heic or .heif file extension. The two terms are often used interchangeably in casual conversation. HEIF is the broader open standard; HEIC is Apple's version of it. Other companies use HEIF too, sometimes with different extensions such as .avif for the AV1-based variant.
Is it safe to use an online HEIC to JPG converter?
For photos of everyday subjects without sensitive content, reputable online converters are safe. The concern is EXIF metadata: iPhone photos often contain GPS coordinates, camera model, timestamps, and other personal details. If your photos include location data from home, work, or personal events, converting locally via Preview or Windows Photos keeps that data off third-party servers. Use a browser-based EXIF removal tool to strip metadata before sharing any photo publicly.
Does converting HEIC to JPG reduce quality?
Converting at high quality settings (90-100%) produces minimal visible quality loss. HEIC supports 16-bit color per channel, versus JPEG's 8-bit, so some color depth is technically lost in conversion (Cloudinary, 2024). For everyday use, phone screens, and standard print sizes, the difference is invisible. For professional photography destined for large-format printing or HDR displays, use the maximum quality JPEG setting in your conversion tool to preserve as much color information as possible.
How do I bulk convert HEIC files to JPG on Windows?
First, install the free HEIF Image Extensions codec from the Microsoft Store. Without it, Windows Photos shows a blank screen on HEIC files. Once installed, select multiple .heic files in File Explorer, right-click, choose Open with > Photos, and use Save a copy to export each as JPEG. For a one-step batch process with no manual clicking, IrfanView (free from irfanview.com) converts all selected HEIC files to JPEG in a single run via its Batch Conversion feature.
Why does my iPhone take HEIC photos instead of JPEG?
Apple switched iPhones to HEIC as the default format in iOS 11, released in September 2017, because HEIC files are roughly 50% smaller than equivalent JPEGs at the same visual quality (Cloudinary, 2024). On a 128 GB iPhone, that difference translates to roughly twice as many photos stored before the device runs out of space. To shoot JPEG instead, go to Settings > Camera > Formats and select Most Compatible.
