What Is EXIF Data in Your Photos?
Your photos carry a hidden record of how, when, and sometimes exactly where they were taken.
EXIF is metadata tucked inside your image file — a record the camera writes alongside the picture. Shutter speed, aperture, ISO, lens, the exact date and time, the camera's orientation, and on a phone, very often the GPS coordinates of where you stood.
It's invisible in normal use, and mostly harmless. But it explains a few things that otherwise make no sense, and it has one implication worth taking seriously.
The mystery it explains
If you've ever had a photo appear upright on your phone and sideways everywhere else, EXIF is why.
When you rotate your phone to shoot, the camera usually doesn't rotate the pixels — it writes an orientation tag saying "display this rotated." Your phone reads the tag and obliges. Plenty of older software, upload forms, and processing pipelines ignore it and show the raw pixels, which are sideways.
The photo was always sideways. Your phone was being polite. Our guide on rotating and flipping covers the fix — rotating properly bakes the transform into the pixels so nothing has to honour a tag.
The part that matters: location
Here's the one to actually think about. If location services were on when you took a photo, the file very likely contains the coordinates of where you were standing, accurate to a few metres.
That's genuinely useful in your own library — it's what puts your holiday photos on a map. It's a different proposition when you post the picture publicly. A photo of your cat, taken in your living room, can carry your home address in a form anyone can read with free software.
The reassuring bit: most major social platforms strip EXIF when you upload, both for privacy and to save bytes. The unreassuring bit: "most" isn't "all", and it doesn't cover a file you email, put in a shared folder, or upload to a forum or marketplace listing. Selling something from home and uploading the original camera file is the case worth pausing on.
How to remove EXIF data
You don't need a dedicated tool. Most image processing quietly drops EXIF as a side effect, because the tool decodes the picture into raw pixels and encodes a fresh file — and the new file has no reason to carry the old metadata.
So running a photo through Compress Image, Resize Image, Crop Image, or a format conversion like PNG to JPG will generally produce a file without the original EXIF. You were probably going to do one of those anyway before uploading.
Three honest caveats. First, this is a side effect rather than a guarantee — if stripping location data is a safety matter rather than a tidiness one, verify the output with an EXIF viewer rather than trusting a rule of thumb.
Second, Compress Image is the one to watch. If re-encoding your file would make it bigger, it hands back your original untouched — which is good behaviour for file size and useless for stripping metadata, because the original still has all of it. Resizing, cropping, and converting always re-encode, so they're the reliable routes.
Third, it's all-or-nothing: you lose the camera settings along with the coordinates, which photographers sometimes want to keep.
When you want to keep it
EXIF isn't the enemy. It's how you know what settings produced a shot you liked, how your library sorts chronologically, how photos land on a map, and how a photographer proves provenance. Losing it wholesale to strip one field is a real cost.
The sane habit: keep your originals with metadata intact, and let the processed copy you actually share be the one that's been through a tool. That's the same discipline that protects you from generation loss — original stays pristine, copy goes out into the world.
And if you were hoping stripping EXIF would shrink a heavy file: it won't. Metadata is a few kilobytes at most. Our guide on why images get so big covers what actually accounts for the weight.
FAQ
Does EXIF data include my location?
Often, if location services were enabled when you shot. It can be accurate to a few metres.
Do social media sites remove EXIF?
Major platforms generally strip it on upload. Emailing a file, sharing a folder, or posting to a smaller site may not.
How do I remove EXIF data?
Most processing drops it as a side effect — compressing, resizing, cropping, or converting all typically produce a clean file. If it's a safety matter, verify with an EXIF viewer rather than assuming.
