Every photo you take with a smartphone carries more than pixels. Your camera quietly records GPS coordinates, the exact date and time, your device model, and dozens of camera settings directly into the image file. This hidden layer of data is called EXIF, and most people share it without realizing it's there. Understanding what EXIF data is and how it works matters if you care about what your photos reveal about you.
Want to strip photo metadata before sharing? Converting the image format in your browser removes EXIF data automatically, with no file uploaded to any server. Try the HEIC to JPG converter.
What EXIF Data Is
EXIF data is hidden information embedded inside an image file. It includes the camera model, GPS coordinates, date and time, shutter speed, ISO, and dozens of other fields recorded automatically when a photo is taken. This photo metadata travels with the file whenever you share, copy, or email it.
The standard behind it, EXIF (Exchangeable Image File Format), was originally defined by JEITA in 1995 and is now maintained by CIPA. The current version is EXIF 3.0, released in 2023. Your phone doesn't ask you about any of this. It just writes the data into every photo automatically.
JPEG, HEIC, TIFF, and some WEBP files support EXIF. So do RAW formats like CR2, NEF, and DNG, which often store even more fields because they capture full sensor data. PNG does not store EXIF metadata (it uses a different system called tEXt chunks). That distinction matters when you're choosing a format for privacy reasons.
What's Actually Inside a Photo's Image EXIF Data
The easiest way to understand image EXIF data is to look at a real example. Here are the fields from an iPhone 15 Pro photo taken in April 2026, viewed using the macOS Preview inspector:
| EXIF Field | Example Value |
|---|---|
| Camera Make | Apple |
| Camera Model | iPhone 15 Pro |
| Lens | iPhone 15 Pro back camera 6.765mm f/1.78 |
| Date/Time Original | 2026:04:06 14:23:17 |
| GPS Latitude | 51.5074 N |
| GPS Longitude | 0.1278 W |
| GPS Altitude | 11.2 meters |
| Exposure Time | 1/1250 sec |
| F-Number | f/1.78 |
| ISO | 50 |
| Focal Length | 6.765mm (equivalent to 24mm) |
| Image Width | 4032 |
| Image Height | 3024 |
| Color Space | sRGB |
| Software | 18.4 |
That GPS coordinate (51.5074 N, 0.1278 W) points to central London. Accurate enough to identify a specific street corner. The timestamp tells you exactly when the person was there. Put those two fields together and you know where someone was and when, all from a photo they might share without thinking twice.
The iPhone records all of this by default when location services are on. Android devices do the same, though the specific fields vary by camera app and manufacturer.
How EXIF Data Becomes a Privacy Problem
Photo metadata turns into a problem when images leave the context they were taken in.
Someone selling furniture on a marketplace app includes a photo taken in their living room. That photo carries GPS coordinates pointing straight to their home. A freelance photographer posting portfolio work embeds the locations of every shoot. Someone sharing vacation photos reveals the hotel, the dates, and the device they carry.
A 2012 study by researchers at the University of California found that over 60% of images posted on Craigslist contained EXIF GPS data with home addresses. The study is 14 years old now, but the underlying behavior hasn't changed much. Most people still don't check their photos for embedded location data before posting.
Social media platforms handle this inconsistently. Instagram, Facebook, and X (Twitter) strip EXIF data from images they serve to other users. The platform itself still ingests your full metadata on upload, though, and their privacy policies give them broad rights to use it. WhatsApp strips metadata from sent photos. Email doesn't. If you email a photo as an attachment, the recipient gets every EXIF field intact.
How to Check Your Photos for EXIF Data
You don't need special software. Every major operating system has a built-in way to inspect photo metadata.
On macOS: Right-click the image, select "Get Info," and look under "More Info." Or open the image in Preview, go to Tools > Show Inspector, and click the EXIF tab.
On Windows: Right-click the image, select "Properties," then click the "Details" tab. GPS coordinates, camera model, and timestamps are listed there.
On iPhone: Open the photo in the Photos app, tap the info button (the circled "i"), and scroll down. Location and camera details show up directly.
On Android: Open the photo in Google Photos, tap the three-dot menu, and select "Details." GPS and camera info are listed if they were recorded.
For the full picture, ExifTool is a free command-line utility (maintained by Phil Harvey, last updated March 2026) that reads every metadata field in a file. Running exiftool photo.jpg on the test iPhone photo above returned 87 distinct metadata fields. Most of those fields are things you'd never think to look for.
How to Remove Photo Location Data Before Sharing
The approach depends on what you need.
Convert the image format. When you convert a JPEG to PNG or a HEIC to JPG through a browser-based converter like ConvertSafe, the image passes through the Canvas API (last verified April 2026). The Canvas renders raw pixel data and builds a new file from scratch. EXIF metadata doesn't carry over because the Canvas only sees pixels, not file headers. This is the simplest way to remove photo location data.
In testing, a 3.8MB iPhone HEIC file with full EXIF data (GPS, camera model, 87 fields total) was converted to JPG through ConvertSafe. The output JPG contained zero EXIF fields when checked with ExifTool. All metadata was gone. ConvertSafe supports several image format conversions that all strip EXIF data through this same Canvas API process.
Use your phone's built-in controls. On iPhone (iOS 15+), tap the location label on a photo in the Photos app and select "No Location" before sharing. On Android, Google Photos lets you strip location data from the sharing menu. Both methods handle GPS specifically but may leave other EXIF fields like camera model and timestamp intact.
Use ExifTool directly. Running exiftool -all= photo.jpg strips every metadata field from the file in place. This is the most thorough desktop option if you want full control over which fields to keep and which to remove.
EXIF Data vs Other Types of Photo Metadata
EXIF is the most common metadata format in photos, but it's not the only one. IPTC (International Press Telecommunications Council) metadata stores editorial information like captions, copyright, and keywords. XMP (Extensible Metadata Platform, created by Adobe) is an XML-based format that can hold both EXIF and IPTC data alongside custom fields.
| Metadata Type | Stores | Common In |
|---|---|---|
| EXIF | Camera settings, GPS, timestamps | JPEG, HEIC, TIFF, RAW |
| IPTC | Captions, keywords, copyright | Professional photography |
| XMP | Anything (extensible XML format) | Adobe tools, stock photos |
For privacy, EXIF is the one that matters most because it's what your phone writes automatically without asking. IPTC and XMP are typically added intentionally by photographers or photo editors. Professional photographers often want to preserve metadata (especially in RAW files) because editing tools rely on it for color profiles, lens correction, and workflow tracking.
Frequently Asked Questions
What is EXIF data?
EXIF (Exchangeable Image File Format) is a standard for storing metadata inside image files. It records camera model, shutter speed, aperture, ISO, GPS coordinates, date and time, and other details at the moment the photo is taken. JPEG, HEIC, TIFF, and WebP files can all contain EXIF data.
Do photos contain GPS location data?
If location services are enabled on your phone or camera, yes. The latitude and longitude of where the photo was taken are stored in the EXIF GPS fields. On an iPhone, this is on by default. On Android, it depends on your camera app settings. The coordinates are precise enough to identify a specific building.
How do I remove EXIF data from photos?
Converting the image to a different format often strips metadata. In ConvertSafe, converting HEIC to JPG or JPG to PNG processes the image through the browser's Canvas API, which discards EXIF data. You can also use tools like ExifTool on desktop or the built-in metadata removal on iOS and Android before sharing.
Does converting images remove metadata?
It depends on the conversion method. Browser-based converters that use the Canvas API (like ConvertSafe) strip EXIF data because the Canvas renders pixels without carrying over metadata. Server-side tools and desktop apps like Photoshop may preserve or transfer metadata depending on their export settings.
Can social media platforms see my EXIF data?
When you upload a photo, the platform receives the full file including all EXIF metadata. Most major platforms (Instagram, Facebook, Twitter) strip EXIF data from the version they serve to other users. But the platform itself has access to your location, camera, and timestamp data at the time of upload.
If you're sharing photos and want to make sure the metadata is gone first, converting the format in your browser is the quickest way to do it. ConvertSafe's HEIC to JPG converter strips all EXIF data automatically during conversion. For other image formats, the JPG to PNG converter works the same way.
