Every digital photo contains more than just pixels. Embedded inside the file is a block of invisible data called EXIF metadata. It records everything from GPS coordinates and camera settings to the exact second the photo was taken. This data travels with the file wherever it goes, unless you deliberately remove it.
This guide covers what EXIF data is, how to view it, what it reveals about you, and how to control it.
EXIF Data Explained
EXIF (Exchangeable Image File Format) is a metadata standard developed in 1995 by the Japan Electronic Industries Development Association (JEIDA). It defines a set of fields that cameras and imaging software embed directly into image files at the moment of capture.
EXIF metadata is stored in the file header, before the actual image pixel data begins. It occupies a small amount of space, typically 5 to 50 KB, depending on how many fields the camera populates. The metadata is invisible when viewing the image. You need a dedicated tool, software, or the file properties dialog to read it.
EXIF is supported by JPG, TIFF, and some WebP and HEIF files. PNG files do not support EXIF natively but can contain similar metadata in other formats (tEXt, iTXt chunks).
What Information Does EXIF Contain?
EXIF metadata is organized into several categories. Here is a breakdown of the most common fields:
Location data:
| Field | Example value | Description |
|---|---|---|
| GPSLatitude | 48.8566 | Geographic latitude |
| GPSLongitude | 2.3522 | Geographic longitude |
| GPSAltitude | 35 m | Altitude above sea level |
| GPSSpeed | 0 km/h | Speed at capture (some devices) |
Date and time:
| Field | Example value |
|---|---|
| DateTimeOriginal | 2026:03:15 14:32:07 |
| DateTimeDigitized | 2026:03:15 14:32:07 |
| OffsetTimeOriginal | +01:00 |
Camera and lens:
| Field | Example value |
|---|---|
| Make | Apple |
| Model | iPhone 16 Pro |
| LensModel | iPhone 16 Pro back camera 6.765mm f/1.78 |
| SerialNumber | DNQXXX123456 |
| ImageUniqueID | a3f2b1c4d5e6 |
Capture settings:
| Field | Example value |
|---|---|
| ExposureTime | 1/250 s |
| FNumber | f/1.78 |
| ISO | 64 |
| FocalLength | 6.765 mm |
| FocalLengthIn35mmFilm | 24 mm |
| WhiteBalance | Auto |
| Flash | No flash |
Software and processing:
| Field | Example value |
|---|---|
| Software | Adobe Lightroom 7.2 |
| ProcessingSoftware | Photos 9.0 |
| ColorSpace | sRGB |
| Orientation | Rotate 90 CW |
A single smartphone photo can contain over 100 EXIF fields. Professional cameras with GPS modules can record even more, including compass direction, scene type, and lens aberration correction profiles.
How to View EXIF Data
On Windows: right-click the image file, select Properties, go to the Details tab. You will see camera settings, dates, and sometimes GPS data.
On macOS: open the image in Preview, press Cmd+I, and click the "More Info" tab. For GPS data, open in Photos and check the Info panel.
On smartphones: most gallery apps show basic EXIF data (date, location) when you view photo details. On iPhone, open the photo and swipe up or tap the info button. On Android, open in Google Photos and tap the three-dot menu, then Details.
Online tools: upload the image to an EXIF viewer website to see the complete metadata. Note that uploading a photo to a third-party site may itself be a privacy concern.
Command line (exiftool): the most complete option. Running exiftool photo.jpg displays every metadata field in the file, including fields that GUI tools often hide.
EXIF and Privacy | What You Reveal Without Knowing
Most people are unaware that their photos contain location data. Here are concrete examples of what EXIF data can reveal:
Your home address. Photos taken at home, which includes photos of items for sale, pets, food, home projects, contain GPS coordinates that pinpoint your home to within a few meters.
Your daily routine. A series of photos taken over days or weeks creates a map of the places you visit: home, workplace, gym, school, restaurants. Combined with timestamps, it reveals when you are typically at each location.
Your device identity. Camera serial numbers and unique image IDs allow someone to correlate photos posted on different platforms to the same device, and therefore the same person, even if the accounts use different names.
Your financial situation. Camera model and lens data reveal the equipment you own. Combined with location data, this provides a picture of your lifestyle.
Your travel history. Vacation photos contain GPS data from every location you visited, along with exact dates.
Which Platforms Strip EXIF Automatically?
Major social media platforms remove EXIF metadata from uploaded photos, but the behavior varies:
| Platform | Strips GPS? | Strips device info? | Strips all EXIF? |
|---|---|---|---|
| Yes | Yes | Yes | |
| Yes | Yes | Yes | |
| Twitter/X | Yes | Yes | Yes |
| Yes | Yes | Mostly | |
| Yes | Yes | Yes | |
| Telegram (compressed) | Yes | Yes | Yes |
| Telegram (as document) | No | No | No |
| Signal (standard) | Yes | Yes | Yes |
| Signal (original quality) | No | No | No |
| Discord | Yes | Partial | Partial |
| Reddit (direct upload) | Yes | Yes | Yes |
| Forums, personal blogs | Usually no | Usually no | Usually no |
| Email attachments | No | No | No |
The critical takeaway: major platforms strip EXIF, but many sharing methods do not. Email, direct file transfer, "send as document" modes in messaging apps, personal websites, and smaller platforms often preserve the full metadata.
How to Remove EXIF Data
The safest approach is to remove metadata before sharing, regardless of the platform. This way, you are not relying on a third party's stripping behavior, which can change without notice.
With Morphix:
- Go to the Remove Metadata page.
- Drop your photo on the upload area.
- Click Remove Metadata.
- Download the clean file.
All EXIF, IPTC, and XMP metadata is removed. The image quality is not affected. Orientation is applied to the pixel data before the flag is removed, so the image displays correctly everywhere.
Check and Remove Metadata
Morphix removes all metadata from your photos directly in the browser. No registration required for the free plan.
