LINE image lab: what can a local JPEG tell you before you pick a LINE path?
Before I send a LINE photo in chat, an album, Keep, or as a file, is GPS still in the JPEG I have open?
LINE chat, album, Keep, and file send are separate paths. The local JPEG’s GPS and camera fields were absent after the clean. A help page that skips those words is not this comparison. Clean the copy in this browser before sending. The file stays on this device and is not uploaded to this site.
A help article can skip the words EXIF and GPS and still leave you with a file that contains both. The check is the file you are holding.
Short answer
Direct answer: the local sample’s GPS and camera fields were removed in the cleaned copy. That does not collapse chat, album, Keep, and file send into one rule.
- What was measured: On 1 November 2026 the viewer read GPS and camera-style fields in the local JPEG. The cleaner copy omitted them.
- What that does not prove: Album, chat, Keep, and file send stay separate paths. This comparison does not merge them.
- What you can do first: Clean the copy in this browser before the file leaves the device. Nothing is uploaded to this site.

What we measured
Sample dated 2026-11-01. The viewer read location and camera fields. The cleaned file no longer has them. The file stayed on this device.
| Field | Local sample (viewer) | Cleaned copy (cleaner) |
|---|---|---|
| GPS / location | 35 deg 0' 0.00" N, 135 deg 0' 0.00" E | No GPS |
| EXIF | EXIF present (camera make, model, and settings) | EXIF fields cleared |
| Camera information | Camera make and model present | Camera make and model removed |
| Timestamps | 2026:11:01 18:00:00 | Capture time removed |
| Provenance / C2PA | JUMBF APP11 and a C2PA container | No C2PA or JUMBF container |
| Recompression / resize | 378,066 bytes, with location and the metadata above | 361,097 bytes; metadata removed, image scans unchanged |
GPS / location
The viewer read 35 deg 0' 0.00" N, 135 deg 0' 0.00" E. The cleaned file had no GPS.
EXIF
The viewer read a camera make, a model, and the capture time 2026:11:01 18:00:00. The cleaned file had no EXIF.
Test environment
Chrome 156.0.8078.47 and ExifTool 12.76. The file stayed on this device. Nothing was uploaded.
How to test your own file
- Plant GPS and camera fields in a JPEG.
- Send via the exact LINE path you care about (chat image vs Keep vs file).
- Download from the receiving side.
- Compare hash and GPS tags.
- Record iOS and Android separately; LINE versions matter.
Methodology
Every published result has to follow the same protocol: a known source file, a recorded hash, a specific upload path, and a downloaded copy. Folklore does not count.
Privacy implications
If a photo could identify a home, school, or workplace, strip location on the file before it enters LINE. Platform folklore is not a control.
