How to remove EXIF data from photos before sharing
Every photo your phone takes has hidden information attached. Some of it is harmless (lens focal length, ISO). Some of it is not — most importantly, the GPS coordinates of exactly where the photo was taken. Here's what's actually inside your photos, and how to clean them up before posting publicly.

What EXIF actually contains
EXIF (Exchangeable Image File Format) is metadata embedded in JPEG and TIFF files. A typical iPhone photo includes: camera make/model, lens, focal length, ISO, shutter speed, aperture, software version, capture date, and GPS coordinates accurate to a few meters. Some Android phones add even more — barometric altitude, magnetic heading, even sensor temperature. None of this is visible when you view the photo, but it's all there in the file.
Why GPS data matters
If you post a photo of your kid in your back garden, GPS data tells anyone with the file exactly where you live. If you post a vacation photo, you've also broadcast that your home is empty. If you photograph a sensitive document at work, your employer's office address is leaked. Most social platforms strip EXIF on upload (Instagram, X, Facebook) — but private shares (email, WhatsApp originals, cloud links, AirDrop) preserve it intact.
Beyond GPS: what else gets exposed
The capture timestamp can confirm whether you were somewhere at a given time. The camera serial number (some cameras include it) can tie multiple photos to the same physical device — useful for journalists protecting sources, dangerous if leaked. Software-version metadata can identify whether a photo was edited and with what tool. None of these are dealbreakers individually, but they add up.
How to strip it out
Three options: 1) Take a screenshot of the photo (effective but loses quality). 2) Use your phone's built-in privacy options (iOS: 'Options' → 'All Photos Data' off when sharing; Android: location-tag toggle in camera app). 3) Use a metadata stripper that processes the file directly — strips APP1 (EXIF), APP13 (IPTC), and XMP markers without touching the pixel data. Our EXIF Viewer tool does this in your browser without uploading.
What stays, what goes
When EXIF is stripped properly, the image looks identical (pixel-for-pixel) but file size shrinks by 10-50 KB. The image's intrinsic info (dimensions, color space) stays — that's part of the image data, not metadata. PNG and WebP also have metadata, though it's usually less revealing. PNG can carry XMP and tEXt chunks; WebP can embed EXIF too. Strip both before posting if privacy matters.
