HEIC to JPG: How to Convert iPhone Photos

4 min read

Why Does My iPhone Use HEIC?

Starting with iOS 11, Apple adopted HEIC (High Efficiency Image Container) as the default photo format for iPhones. You can quickly convert HEIC to JPG right in your browser. HEIC uses the HEIF (High Efficiency Image Format) standard, which provides significantly better compression than JPEG while maintaining the same visual quality.

A typical iPhone photo in HEIC format is about 40-50% smaller than the equivalent JPEG. For a phone that takes thousands of photos, this saves gigabytes of storage space. HEIC also supports features that JPEG cannot, including:

  • 16-bit color depth (vs JPEG’s 8-bit), enabling smoother gradients
  • Transparency (alpha channel support, like PNG)
  • Multiple images in one file (Live Photos, bursts, depth maps)
  • Non-destructive edits stored within the file
  • HDR data for improved dynamic range

The Compatibility Problem

Despite its technical advantages, HEIC is not universally supported. You will encounter compatibility issues when:

  • Uploading to websites — Many web forms and CMS platforms do not accept HEIC uploads.
  • Sharing with non-Apple users — Windows PCs, Android devices, and some software cannot open HEIC files without additional codecs.
  • Using older software — Photo editors, document tools, and social media platforms may not support HEIC.
  • Printing services — Many online print services require JPEG or PNG uploads.
  • Email attachments — Some email clients cannot preview HEIC files.

When you share photos from your iPhone via AirDrop to a Mac, or through iMessage, iOS often handles the conversion automatically. But when you transfer photos via USB, download from iCloud, or access them directly from your phone’s file system, you get the raw HEIC files.

Method 1: Convert in Your Browser

The fastest and most private way to convert HEIC to JPG is using a browser-based tool. The noupload Image Format Converter converts HEIC to JPG, PNG, or WebP directly in your browser. Your photos never leave your device.

  1. Open the Image Format Converter
  2. Drop your HEIC file(s) into the upload area
  3. Select JPG as the output format
  4. Choose your quality level (90% recommended for near-lossless conversion)
  5. Download the converted file

This method works on any device with a modern browser, including Windows, Mac, Linux, and even other phones.

Method 2: Change iPhone Settings

You can configure your iPhone to save photos as JPEG instead of HEIC going forward:

  1. Open Settings
  2. Go to Camera > Formats
  3. Select Most Compatible

This changes the capture format from HEIC to JPEG. The trade-off is that photos will take up roughly twice as much storage space. If you have a large-capacity phone and frequently share photos with non-Apple users, this can be a reasonable choice.

Note: This only affects future photos. Existing HEIC photos remain in HEIC format.

Method 3: Transfer Settings

iOS can automatically convert HEIC to JPEG when transferring photos to a PC:

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

With “Automatic” selected, iOS converts HEIC to JPEG during USB transfers. However, this does not apply to iCloud downloads, AirDrop, or email attachments.

Method 4: Preview on Mac

macOS Preview can convert HEIC files natively:

  1. Open the HEIC file in Preview
  2. Go to File > Export
  3. Choose JPEG as the format
  4. Set the quality slider (80-90% is usually ideal)
  5. Click Save

For batch conversion, select multiple files in Finder, right-click, and choose Quick Actions > Convert Image.

Method 5: Windows

Windows 10 and 11 support HEIC viewing if you install the free HEIF Image Extensions from the Microsoft Store. For conversion, use the Photos app’s export feature, or use a browser-based tool like noupload for batch conversion without installing anything.

Quality Considerations

When converting HEIC to JPEG, you are going from a more efficient format to a less efficient one. To minimize quality loss:

  • Use 90-95% JPEG quality for photos you want to look nearly identical to the original.
  • Use 80-85% quality for general sharing where file size matters more than perfection.
  • Avoid converting multiple times — Each JPEG re-save introduces additional compression artifacts. Convert from the original HEIC once.

If you need transparency support or lossless quality, convert to PNG instead of JPEG. PNG files will be larger but preserve every pixel exactly.

Batch Conversion Tips

If you have hundreds of HEIC photos to convert:

  • Browser tools — The noupload Image Format Converter supports batch uploads, letting you convert multiple files at once.
  • Command line — On macOS, use the sips command: sips -s format jpeg *.HEIC --out ./converted/
  • ExifTool — Can handle HEIC conversion alongside metadata operations.

After Converting

Once your photos are in JPEG format, you might also want to:

  • Compress them — Use the Image Compressor to reduce file size further with adjustable quality.
  • Resize them — The Image Resizer can scale photos to specific dimensions or social media presets.
  • Strip metadata — Remove GPS location and other sensitive EXIF data before sharing online.
