EXIF Data in HEIC and JPG Photos: What You Need to Know

What Is EXIF Data?

Every photo you take with a smartphone or digital camera contains more than just the image itself. Embedded within the file is a block of metadata called EXIF data (Exchangeable Image File Format). This metadata is written automatically at the moment you press the shutter button, and it records a surprising amount of information about the photo and the device that captured it.

Common EXIF fields include:

  • Camera and device info -- Device manufacturer, model name, lens specifications, and software version.
  • Capture settings -- Shutter speed, aperture (f-stop), ISO sensitivity, focal length, and whether the flash fired.
  • Date and time -- The exact timestamp when the photo was taken, often down to the second.
  • GPS location -- Latitude, longitude, and sometimes altitude, pinpointing exactly where the photo was captured.
  • Orientation -- Whether the phone was held in portrait or landscape mode, so software can rotate the image correctly.
  • Thumbnail -- A small preview image embedded inside the file for quick display.

This metadata can be extremely useful for photographers, but it can also raise serious privacy concerns -- especially the GPS coordinates.

EXIF in HEIC vs JPG

Both HEIC and JPG files store EXIF metadata, and the data they contain is largely the same. Apple's HEIC format uses the same EXIF standard that JPG has relied on for decades, so switching between formats does not inherently add or remove metadata categories.

That said, HEIC files from an iPhone can also carry additional Apple-specific metadata, such as depth maps, Live Photo references, and HDR gain maps. This extra data goes beyond the standard EXIF specification and is typically not carried over when converting to JPG.

What Happens to EXIF During Conversion?

This is an important question, and the answer depends on how the conversion is performed. When you convert HEIC to JPG using a browser-based tool like our free converter, the conversion is handled by the browser's image rendering pipeline. In this process:

  • Standard EXIF fields may be stripped. Browser-based conversion decodes the HEIC image into raw pixel data and then re-encodes it as JPG, PNG, or WebP. This re-encoding process does not always preserve the original EXIF metadata.
  • GPS data is typically removed. Since the metadata is not explicitly copied, location information usually does not survive the conversion.
  • Image quality is preserved. The visual content of the photo is fully maintained -- only the invisible metadata is affected.

Desktop applications like Adobe Lightroom or dedicated EXIF tools, on the other hand, often have the ability to explicitly preserve or copy EXIF data during format conversion.

Privacy Benefits of Stripped EXIF Data

For many users, having EXIF data removed during conversion is actually a privacy advantage. Consider the following scenarios:

  • Sharing photos online. When you post a photo to a blog or forum, embedded GPS data could reveal your home address, workplace, or other sensitive locations.
  • Selling items online. Photos of products taken at home may contain coordinates that disclose where you live.
  • Sending photos to strangers. Any recipient can extract EXIF data with free tools, gaining access to your location history and device information.

Because our converter runs entirely in your browser, your photos are never uploaded to a server. Combined with the natural EXIF stripping that occurs during browser-based conversion, this provides a strong layer of privacy protection by default.

When You Want to Keep EXIF Data

Not everyone wants their metadata removed. There are legitimate reasons to preserve it:

  • Photographers rely on EXIF to catalog their work, track camera settings, and organize images by date and location.
  • Legal and forensic use may require original metadata as evidence of when and where a photo was taken.
  • Photo management software like Adobe Lightroom, Google Photos, and Apple Photos uses EXIF data to sort, search, and group images automatically.

If preserving EXIF data is important for your workflow, consider using a desktop application for conversion instead of a browser-based tool, or keep your original HEIC files as an archive.

The Bottom Line

EXIF metadata is a powerful but often invisible part of your photos. Both HEIC and JPG store similar EXIF data, but browser-based conversion tends to strip most of it out -- which is a benefit if privacy is your priority and a consideration if you need to keep that data intact.

If you want a quick, private way to convert your HEIC files while naturally removing embedded metadata, try our free converter. Your photos never leave your device, and the conversion process gives you a clean image file ready to share.
