How to Convert HEIC to JPG: iPhone Photo Format Guide

If you have ever transferred photos from an iPhone to a Windows PC and found yourself unable to open them, you have encountered the HEIC format. Since 2017, Apple has used HEIC as the default photo format on iPhones and iPads, replacing the universally supported JPG. The result is smaller files with better quality, but at the cost of compatibility headaches on non-Apple platforms.

This guide covers everything you need to know about the HEIC format, how it compares to JPG, and the best ways to convert between them. Whether you need to convert a single photo or process an entire library, you will find the right method here.

What Is HEIC?

HEIC stands for High Efficiency Image Container. It is a file format based on the HEIF (High Efficiency Image Format) standard, which itself uses the HEVC (H.265) video codec to compress still images. The format was developed by the Moving Picture Experts Group (MPEG) and adopted as an international standard (ISO/IEC 23008-12) in 2015.

A HEIC file is technically a container, not just an image codec. A single .heic file can store multiple images (including burst photos and Live Photos), depth maps, alpha channels for transparency, EXIF metadata, thumbnails, and non-destructive editing history. This makes HEIC significantly more versatile than JPG, which is limited to a single image per file.

Why Does Apple Use HEIC?

Apple adopted HEIC with iOS 11 in 2017 for one primary reason: storage efficiency. HEIC files are roughly 40-50% smaller than equivalent-quality JPGs. On a device where users take thousands of photos, this translates to significant storage savings.

For perspective, over 10,000 photos, the savings can reach 12-15 GB, making a real difference on devices with limited storage.

Beyond file size, Apple benefits from HEIC's support for:

• 16-bit color depth (vs. 8-bit in JPG), enabling HDR photography and wider color gamuts
• Live Photos stored as a single file combining a still image and a short video clip
• Non-destructive editing where the original image data is preserved alongside edits
• Depth maps for Portrait Mode photos, stored within the same container

Apple made this transition seamless within their ecosystem. AirDrop, iMessage, and iCloud handle HEIC natively. The friction only appears when moving files to non-Apple platforms.

HEIC vs JPG: Detailed Comparison

Where JPG Still Wins

Despite HEIC's technical advantages, JPG remains the more practical choice in many scenarios:

• Universal compatibility: Every device, browser, application, and operating system supports JPG without exception.
• Web publishing: Most websites, social media platforms, and email clients expect JPG.
• Printing services: Online print shops and photo labs almost universally require JPG or TIFF.
• No licensing concerns: JPG is free of patent royalties, while HEVC has a complex licensing landscape.

How to Convert HEIC to JPG

There are several approaches depending on your platform, the number of files, and your technical comfort level.

Method 1: Online Conversion (Fastest)

Online converters are the quickest option when you need to convert a few files without installing any software.

Use our HEIC to JPG converter to convert files directly in your browser. Upload your .heic files, and download the converted JPGs. The process takes seconds and preserves your image quality and EXIF metadata.

This is ideal for converting a few files quickly without installing software. If you need PNG output instead (for transparency or lossless quality), use our HEIC to PNG converter. For details on online conversion security, read our guide on file conversion security and data protection.

Method 2: Change iPhone Settings (Prevent the Problem)

You can configure your iPhone to shoot in JPG instead of HEIC, eliminating the conversion step entirely.

1. Open Settings on your iPhone
2. Scroll down and tap Camera
3. Tap Formats
4. Select Most Compatible (this uses JPG for photos and H.264 for video)

Alternatively, you can keep shooting in HEIC but have the iPhone automatically convert to JPG when transferring:

1. Open Settings
2. Tap Photos
3. Under Transfer to Mac or PC, select Automatic

The "Automatic" setting converts HEIC to JPG on-the-fly when you transfer photos via USB. This gives you the storage benefits of HEIC on the device while ensuring compatibility when sharing files.

Note that switching to "Most Compatible" increases storage usage by roughly 40-50%. If storage is tight, keep HEIC and convert only when needed.

Method 3: Convert on Windows

Windows 10 and 11 can open HEIC files after installing the free HEIF Image Extensions from the Microsoft Store. However, this only enables viewing, not conversion.

Using the Photos app:

1. Install "HEIF Image Extensions" from the Microsoft Store (free)
2. Open the .heic file in Photos, click the three-dot menu, select Save as
3. Choose JPEG from the file type dropdown and save

Using Paint:

1. With the HEIF extensions installed, open the .heic file in Paint
2. Click File > Save as > JPEG picture

For batch conversion on Windows, third-party tools like IrfanView or XnConvert provide more control over output quality and metadata handling.

Method 4: Convert on Mac

macOS has native HEIC support, making conversion straightforward.

Using Preview:

1. Open the .heic file in Preview
2. Click File > Export
3. Select JPEG from the Format dropdown
4. Adjust the quality slider as needed
5. Click Save

Using Automator (batch conversion):

1. Open Automator and create a new Quick Action
2. Set "Workflow receives current" to image files in Finder
3. Add the action Change Type of Images and select JPEG
4. Save the Quick Action with a descriptive name
5. Right-click any selection of HEIC files in Finder, go to Quick Actions, and select your workflow

Using the sips command (terminal):

For power users, macOS includes the sips command-line tool:

sips -s format jpeg input.heic --out output.jpg

To batch convert all HEIC files in a directory:

for file in *.heic; do sips -s format jpeg "$file" --out "${file%.heic}.jpg"; done

Method 5: Convert on Linux

Install libheif and use its conversion tool:

sudo apt install libheif-examples
heif-convert input.heic output.jpg

For batch conversion, loop through all HEIC files in a directory:

for file in *.heic; do heif-convert "$file" "${file%.heic}.jpg"; done

Batch Conversion: Handling Large Photo Libraries

When migrating an entire photo library from HEIC to JPG, efficiency and metadata preservation become critical. Here are the best approaches for large-scale conversion.

Key considerations for batch conversion:

• Folder structure: Choose a tool that preserves your directory organization or allows you to define an output structure.
• EXIF data: Verify that camera metadata, GPS coordinates, and timestamps survive the conversion. Most dedicated conversion tools handle this correctly, but verify with a sample batch first.
• Quality settings: Set a JPG quality of 90-95% before converting thousands of files. This is visually indistinguishable from the original while keeping file sizes reasonable.
• Duplicate management: Decide whether to keep the original HEIC files or delete them after verifying successful conversion.

Our HEIC to JPG converter supports batch uploads, making it practical for converting multiple files without any software installation. For truly large libraries (thousands of files), a desktop tool like XnConvert or a command-line approach with ImageMagick offers more control.

Preserving EXIF Data During Conversion

EXIF (Exchangeable Image File Format) metadata contains valuable information embedded in your photos: camera model, exposure settings, focal length, ISO, GPS coordinates, date and time, and orientation. Losing this data during conversion means losing the context of when and where each photo was taken.

How to ensure EXIF preservation:

• Use quality conversion tools: Reputable converters transfer EXIF data from the source HEIC to the output JPG automatically.
• Verify after conversion: Use an EXIF viewer (like ExifTool or your OS file properties dialog) to confirm metadata is intact.
• Watch for orientation issues: HEIC files store rotation in EXIF orientation tags. Some converters may not apply this correctly, resulting in rotated JPGs.
• GPS data privacy: Converted JPGs will contain the same GPS location data as the originals. If sharing photos publicly, consider stripping location data with ExifTool: exiftool -gps:all= output.jpg

Quality Considerations: What You Lose in Conversion

Converting from HEIC to JPG is inherently a lossy process, even when using maximum quality settings. Here is what changes:

Color depth reduction: HEIC supports 16-bit color (65,536 shades per channel), while JPG is limited to 8-bit (256 shades). Photos with subtle gradients may show slight banding after conversion, though for most photography this difference is imperceptible.

Compression artifacts: JPG uses DCT compression, which can introduce blocky artifacts at lower quality settings. HEIC's HEVC compression produces fewer visible artifacts at the same file size. Use a JPG quality of 92-95% to minimize artifact introduction.

HDR data loss: If your iPhone captured a photo in HDR with a wide color gamut (Display P3), converting to JPG maps those colors to sRGB. Bright, saturated colors may appear slightly muted. For color-critical work, consider converting to PNG instead, which supports lossless compression.

Increased file size: Converting to JPG often results in a larger file at equivalent visual quality. A 2 MB HEIC file might become a 3-4 MB JPG at quality 95%, because HEVC compression is more efficient than JPEG's older algorithm. For context on compression methods, see our guide on lossy vs lossless compression.

What you do NOT lose: Resolution, EXIF metadata (with proper tools), and the fundamental image content. For everyday use, social media, email, and printing, a high-quality JPG conversion is perfectly adequate.

Alternative Formats to Consider

If compatibility is your main concern but you want better quality or features than JPG, consider these alternatives:

• PNG: Lossless compression, supports transparency. Larger files but no quality loss. Use our HEIC to PNG converter when you need lossless output. You can also convert between JPG and PNG or PNG and JPG as needed.
• WebP: Developed by Google, WebP offers both lossy and lossless compression with significantly better efficiency than JPG. Browser support is now universal. Convert using our JPG to WebP or PNG to WebP converters. For a detailed format comparison, read our WebP vs PNG vs JPEG guide.
• AVIF: The newest contender, based on the AV1 video codec. Even better compression than WebP, with growing browser and OS support. AVIF may eventually replace both HEIC and JPG for most use cases.
