EXIF Data Viewer reads and displays the metadata embedded in image files. Upload a JPEG, PNG, TIFF, or HEIC photo to see EXIF tags: camera model, lens, exposure settings (aperture, shutter speed, ISO), GPS coordinates, capture date/time, and software used. All processing happens in your browser -- your image is never uploaded to a server. Use it to verify metadata before sharing photos or to extract GPS data from geotagged images.
EXIF (Exchangeable Image File Format) is a metadata standard for images, defined by the Camera and Imaging Products Association (CIPA). EXIF data is embedded in JPEG, TIFF, and some PNG files by cameras and smartphones. Common EXIF tags: Make/Model (camera), DateTime, DateTimeOriginal (capture time), GPSLatitude/GPSLongitude (location), ExposureTime (shutter speed), FNumber (aperture), ISOSpeedRatings, FocalLength, Flash, Software (editing software).
Privacy note: EXIF GPS data reveals exactly where a photo was taken -- this can be a serious privacy risk when sharing photos. Social media platforms (Instagram, Twitter/X, Facebook) automatically strip EXIF data when you upload photos. But directly shared files retain all EXIF data. Tools to remove EXIF: ExifTool (command-line), digiKam, or online EXIF strippers. In macOS: Photos app preserves EXIF; AirDrop shares the original with EXIF intact.

What is EXIF data and why does it matter for privacy?
EXIF data is metadata embedded in image files by cameras and smartphones. It records technical settings (aperture, shutter speed, ISO), the camera model, the exact date and time of capture, and -- most importantly for privacy -- GPS coordinates (latitude, longitude, altitude) if location services were enabled. This means a photo shared via direct file transfer reveals: where the photo was taken (to within meters), what device took it, and when. Photos shared on social media platforms are typically stripped of EXIF automatically, but photos shared via email, messaging apps, or file links may retain all EXIF.
How do I remove EXIF data from photos before sharing?
Options for EXIF removal: macOS: drag the image to Preview -> File -> Export (saves without EXIF, select image format). Or: right-click in Finder -> Quick Actions -> Remove Location. iPhone: when sharing, iOS shows a location sharing prompt for photos -- tap Options and turn off location. Windows: right-click image -> Properties -> Details tab -> 'Remove Properties and Personal Information'. ExifTool (command line): exiftool -all= photo.jpg (removes all EXIF). Online tools: exifpurge.com, removemeta.com. Python: pip install Pillow; from PIL import Image; img.save('clean.jpg', exif=b'').
What do aperture, shutter speed, and ISO mean?
Aperture (FNumber): the size of the lens opening (f/1.8, f/4, f/16). Lower number = larger opening = more light in = shallower depth of field (blurry background). Higher number = smaller opening = sharper background but less light. Shutter speed (ExposureTime): how long the sensor is exposed (1/1000s, 1/60s, 1s). Faster = freeze motion. Slower = motion blur, needs stable camera. ISO (ISOSpeedRatings): sensor sensitivity (100, 400, 3200). Higher = brighter in low light but more digital noise (grain). The exposure triangle: these three settings balance to achieve correct exposure.
How do GPS coordinates in EXIF work?
EXIF GPS data stores: GPSLatitude (decimal degrees N/S, e.g., 35.6762 N), GPSLongitude (decimal degrees E/W, e.g., 139.6503 E), GPSAltitude (meters above sea level), and optionally GPSSpeed, GPSImgDirection (compass heading). Coordinates are stored in degrees-minutes-seconds (DMS) format in the raw EXIF but converted to decimal degrees for display. To view on a map: convert DMS to decimal (degrees + minutes/60 + seconds/3600), then use as lat/lon in Google Maps, OpenStreetMap, or any mapping API. Accuracy: smartphone GPS is typically accurate to 5-10 meters.
Why does my EXIF show the wrong date or time?
Common causes of incorrect EXIF timestamps: (1) Camera clock not set correctly -- especially after battery replacement or new camera. (2) Timezone mismatch: EXIF DateTimeOriginal stores local time without timezone info. If you travel, the camera records local time but GPS data may be in UTC. (3) Scanned photos: scanners set the scan date as the EXIF date, not the original photo date. (4) Image editing: some editors update DateTime to the edit time. ExifTool can fix timestamps: exiftool -DateTimeOriginal+='0:00:00 01:00:00' photo.jpg (adds 1 hour). digiKam and Lightroom have batch timestamp adjustment tools.
