What EXIF is and what your file reveals

Updated: August 25, 2026

Every photo is two different contents in one file. The first is visible: the picture itself. The second is shown by no ordinary viewer, yet any program reads it in a fraction of a second. That is EXIF — a set of service fields where the camera records the circumstances of the shot and editors add their own.

The format was invented in the nineties so photographers could make sense of their own archives: what shutter speed, which lens, exactly when the button was pressed. An honest and useful goal. The side effect appeared later, when files started travelling the internet with all that service filling still inside.

What is inside

• Make and Model — the manufacturer and model of the camera or phone.
• LensModel, ISO, ExposureTime, FNumber — the lens and capture settings.
• DateTimeOriginal — the exact date and time of the shot, down to the second.
• GPSLatitude, GPSLongitude, GPSAltitude — exactly where the photo was taken.
• Artist and Copyright — author and rights holder, if set in the camera or editor.
• Software — what processed the photo and which version.
• SerialNumber and LensSerialNumber — on many models, the serial numbers of that specific body and lens.
• Orientation, ColorSpace, WhiteBalance — technical values a viewer needs.

What it looks like on a real photo

Here is an abridged field set from an ordinary phone photo that passed through an editor:

• Make: Apple; Model: iPhone 15 Pro
• DateTimeOriginal: 2026:08:14 19:42:07
• GPSLatitude: 55 deg 45' 20.90" N; GPSLongitude: 37 deg 37' 2.30" E
• Artist: Ivan Petrov
• Software: Adobe Lightroom 13.2 (Windows)
• LensModel: iPhone 15 Pro back triple camera 6.765mm f/1.78

Six lines, and a portrait already forms: a person with a specific name, a specific phone, paying for Lightroom on Windows, who took the shot at a given point at 19:42 on 14 August. Not one of those lines was visible in the photograph itself.

Why this is more than technical trivia

Individually the fields look harmless; together they act as connective tissue. A camera serial number is identical across all your photos and links publications made under different names. Date and time paired with coordinates reconstruct a daily routine. The Artist field is filled in once in the settings and then quietly travels into every file for years.

The preview thumbnail stored inside EXIF deserves its own mention. In older editors it could survive from the original frame: the picture was cropped or painted over, yet the thumbnail still showed what was there before. Cases where the thumbnail exposed the contents of an "edited" photo have been discussed publicly more than once.

One more non-obvious consequence: the Software field answers the question "is this an original". A shot presented as untouched, carrying a Lightroom record inside, looks exactly like what it is.

EXIF is not the only block

A JPEG can carry other service records too, and removing EXIF alone leaves them in place:

• IPTC — headline, description, keywords, author name and agency data. Written by stock libraries, newsrooms and cataloguing tools.
• XMP — the same set in Adobe format, added when exporting from Lightroom or Photoshop.
• A text comment (COM) — where software sometimes records the name and version of the build that compressed the file.
• In PNG the metadata role is played by tEXt, zTXt and iTXt chunks plus a separate eXIf block.

The Metadata remover clears all of these at once. After cleaning there is no stock library IPTC field, no editor XMP and no service comment — while the ICC colour profile is preserved so the colours stay correct.

How to see what is in your file

1. Windows: right-click the file → Properties → the Details tab. It does not show everything, but the camera, date, author and GPS are visible immediately.
2. macOS: Preview → Tools → Show Inspector, then the general, EXIF and GPS tabs.
3. Any system: upload the file to our tool — after processing you see how many service fields were removed.

How to clean it

1. Open the Metadata remover.
2. Drag your file onto the upload area — JPEG, PNG, DOCX, XLSX, PPTX, PDF, MP3, MP4 and MOV are supported.
3. Wait for the "Download" link and take the cleaned copy.
4. If you uploaded several files, use "Download all as ZIP" to take them in one archive.

Images are cleaned without re-encoding: quality, resolution and colours stay exactly as they were.

When cleaning is not optional

• Before posting an ad with photos taken at home.
• Before sending a portfolio, a CV or scanned documents.
• Before publishing material received from a contractor or a stock library — it keeps the previous owner's fields.
• Before publishing under a pseudonym, if you also publish under your real name with the same camera.
• Any time a file goes to someone you never meant to tell your phone model, your address and the time of the shot.
