One question, one page.
Every question here gets its own page and a direct answer in the first line. No accordion to open, no article to scroll through to find the sentence you came for.
Metadata in general
What is in a photo, why it is there, and what removing it costs.
- Does screenshotting a photo remove its metadata?Yes, for the original metadata — a screenshot is a new file that never contained it. But you pay for that in resolution, and the screenshot carries its own metadata instead.
- Can image metadata be faked or edited?Yes, all of it. EXIF, IPTC and XMP are plain editable fields, and rewriting them takes seconds with freely available tools. Metadata is a claim, not evidence.
- Do all photos have metadata?Almost every photo straight from a camera or phone does. Images that reach you by other routes often carry very little, and some carry nothing at all.
- Does removing metadata reduce image quality?It does not have to, and here it never does. But a great many tools remove metadata by re-saving the image, and re-saving a JPEG is lossy every single time.
- Why remove metadata from photos?Because the file carries more than the picture: where it was taken, what took it, and when. All of it travels with the photo wherever you send it.
- Why keep the colour profile and orientation tag?Because they describe the image rather than you. Dropping them makes photos display sideways or with washed-out colours, and it protects nothing.
Location and GPS
How precise the coordinates are, and what does and does not remove them.
- Do screenshots contain GPS location data?No. A screenshot is captured from your display, not from your camera, so there is no location fix to record. It does still carry a timestamp and some device information.
- How accurate is the GPS location in a photo?Outdoors with a clear sky, usually within a few metres — precise enough to name the building you were standing in. Indoors it can be far worse, or simply wrong.
- Does turning off location services remove GPS from photos I already took?No. It only changes what happens to future photos. Coordinates were written into each existing file at the moment it was taken, and they are still there.
- Can I remove only the GPS location and keep the rest of the metadata?Yes. GPS is stored in its own section, so it can be removed on its own while camera settings, copyright and timestamps stay untouched.
Reading a file
How to see what a photo is carrying before you decide what to do about it.
- Why does my photo show no EXIF data at all?Almost always because the file has already been through something that removed it — a platform upload, a screenshot, a chat app or an export.
- How do I check whether a photo has metadata?File properties on Windows or Get Info on macOS will show you the basics. A dedicated viewer shows the fields those summaries leave out — which is most of them.
- Can you see a photo's GPS location on a map?Yes, trivially. Coordinates are stored as plain numbers, and anyone holding the file can put them on a map in seconds with no special software.
Fields and standards
What the individual fields are for, and who uses them.
- What is photo metadata used for?Sorting, searching, mapping, editing and copyright. It exists for good reasons — the privacy problem is a side effect of how well it does its job.
- What are examples of image metadata?Coordinates, camera model and serial number, lens, exposure settings, capture time, orientation, colour profile, copyright — and in AI images, the prompt and seed.

What generators embed, and what stripping it does and does not achieve.
Video
What MP4 and MOV files record, and how they are cleaned.
- What metadata do video files carry?Frequently more than a photo. MP4 and MOV files record location, device make and model, creation and modification times, and the encoding software.
- Does removing metadata from a video re-encode it?It does not have to, and here it does not. The metadata boxes are removed and the audio and video streams are copied through bit for bit.
Sharing and platforms
What happens to a file once it leaves your device.
