What EXIF records
Every photo from a camera or phone carries a hidden data block describing how, when, and where it was taken. This viewer parses it from the file bytes locally and lays it out:
| Category | Example fields |
|---|---|
| Camera | Make, model, lens, serial (sometimes) |
| Exposure | Aperture, shutter speed, ISO, focal length |
| Location | GPS latitude/longitude/altitude |
| Time | Capture date, time, sometimes timezone |
| Image | Dimensions, orientation, color space |
For photographers, this is gold — you can study the exact settings behind a great shot. For everyone else, it’s a privacy surface worth understanding.
The two faces of EXIF
EXIF is simultaneously useful and a liability:
- Useful — learn from a photo’s aperture/shutter/ISO, organize a library by capture date, recover the camera settings that produced a look, and read the orientation tag that keeps images upright.
- Liability — GPS and device data leak where you were and what you shot it with (see FAQs).
The same data that helps you also exposes you, which is why knowing how to read it (here) and remove it (above) are both worth having.
Why a photo might have no EXIF
A blank result is usually expected, not a bug: screenshots carry no camera data (the OS captured them), images from social media have been stripped on upload, PNGs from the web rarely hold camera EXIF, and re-saved or edited files often lose metadata if the software didn’t preserve it. If your own phone photo shows nothing, check that location services were enabled for the camera and that the file didn’t pass through a messaging app (WhatsApp, Telegram) that compresses and strips metadata.
A caution on trusting EXIF
EXIF fields are plain metadata and can be edited, added, or removed with ordinary tools — so a timestamp or location in EXIF is not proof of authenticity in any legal or forensic sense; corroborate it with other evidence. It’s a useful first signal, not a verdict. Everything here runs in your browser, so even sensitive photos you’re checking for leaked metadata never leave your device.
