What is EXIF?
EXIF (Exchangeable Image File Format) is metadata written into the file by your camera at the moment of capture. Phones and cameras store a surprising amount:
| Field | Example | Risk level |
|---|---|---|
| Camera & lens model | "iPhone 15 Pro, 24mm f/1.78" | Low — device fingerprint |
| Date & time captured | 2026:08:26 14:32:05 | Medium — reveals patterns |
| GPS coordinates | 39.9042° N, 116.4074° E | High — exact location |
| Serial numbers | Body & lens serials | Medium — links files to you |
| Software / editing history | "Adobe Photoshop 25.1" | Low-medium |
How does GPS get in there?
Phone cameras geotag by default: at capture time, the phone writes its GPS fix into the EXIF GPS block. That's the feature that lets your gallery map your trips — and the same feature that reveals your home address, workplace, or your kid's school when you share the original file.
Who strips EXIF — and who doesn't
Most social networks re-compress uploads and strip metadata in the process. But plenty of channels don't:
- Email attachments (the file goes as-is)
- Chat apps in "document/file" mode
- Cloud drive shared links
- Marketplace listings that accept file uploads
- Anything where the recipient gets the original bytes
Step-by-step: audit and clean a photo
Step 1 — Inspect
Open the EXIF Viewer and drop your photo in. It parses the file locally and shows every field, with a red alert if GPS coordinates are present (including a map link so you can see exactly what's exposed).
Step 2 — Remove
For most sharing, use the EXIF Remover. It offers two depths:
- Segment strip — removes EXIF APP segments surgically, keeping every original pixel byte-identical.
- Full re-encode — decodes the pixels and rebuilds the file from scratch, guaranteeing no metadata container (EXIF, XMP, ICC, comments) survives. Use this for maximum certainty.
Step 3 — Verify
Drag the cleaned file back into the EXIF Viewer. Empty result — proof it worked.
Disable geotagging at the source
On iPhone: Settings → Privacy & Security → Location Services → Camera → Never. On Android: Camera app → Settings → Location tags off. Your future photos will simply not carry coordinates.
What about screenshots and PNGs?
Screenshots rarely carry EXIF, and PNG files generally don't embed camera metadata at all (they can carry other metadata, though). The Metadata Remover full re-encode handles any format if you want certainty across the board.
