What Is EXIF Data? A Plain-English Guide

Every time you take a photo, your camera or phone quietly records a block of information inside the file. That block is called EXIF — short for Exchangeable Image File Format — and most people never see it. Yet it can reveal a surprising amount about a picture and the person who took it.

What EXIF actually contains

EXIF stores technical and contextual details about how a photo was made. The most common fields include:

• Camera make and model — for example Canon EOS R5 or iPhone 16 Pro.
• Exposure settings — aperture, shutter speed, ISO and focal length.
• Date and time the photo was captured.
• Lens information and the software used to edit the file.
• GPS coordinates showing exactly where the picture was taken.

Not every photo contains all of these. A screenshot has almost none, while a RAW file straight from a professional camera can hold dozens of fields, including maker-specific notes.

Why EXIF is useful

For photographers, EXIF is a learning tool. Reviewing the settings behind a great shot — the aperture, the ISO, the lens — helps you understand and repeat it. Archivists and journalists use timestamps and camera identity to organize and verify images.

Why EXIF can be a privacy risk

The same data that helps photographers can expose you. The GPS coordinates embedded by a phone can reveal your home address, your workplace or your daily routine. The timestamp shows when you were somewhere, and the camera model can link photos across accounts.

This is why it is worth checking — and often stripping — the metadata before you share a photo publicly, especially on marketplaces, forums or dating apps that don't remove it for you.

How to view and remove EXIF

You don't need special software. ExifPixel reads and edits metadata entirely in your browser, so your photo never leaves your device. Drop an image into the viewer to see everything it contains, or into the remover to strip it out losslessly.
