Do my photos leave my browser?

No. Parsing, matching, and EXIF writes run on your device. There is no upload endpoint — photos never touch our servers.

Which tool should I use first?

If your camera clock is wrong or you crossed timezones, fix the offset first. Then geotag from a GPX track. Already geotagged? Map the folder or strip GPS before publishing.

Are my originals modified?

Never in place. You download copies or exports. Originals stay untouched on disk.

What replaces GeoSetter, Lightroom, or exiftool?

For the common trip workflow — match photos to a GPS track, fix the clock, check or strip location — gps.so runs in the browser so you do not need a desktop install or a CLI recipe. Heavy RAW/HEIC writing is still limited; JPEG batches are the free path today.

Do I need an account?

No. There are no accounts and no database. Open a tool, drop files, download the result.

gps.so

GPS photo tools that run in your browser.

Geotag from a GPX track, fix camera clocks, strip location EXIF, map a folder — without installing desktop software. Your files never leave your device.

Why this exists · 01

Workflows that still mean “install something”

Converting a GPX file is a solved web problem. Matching a camera roll to a GPS track is not — forum threads still point at GeoSetter, Lightroom, HoudahGeo, or an exiftool one-liner. gps.so is for that gap: photo + GPS jobs that currently require desktop software or the command line, running entirely in your browser.

The hard part is time. Camera clocks drift, trips cross timezones, and GPS tracks are in UTC. We treat the offset as an explicit step — not something the tool invents for you.

Four entry points, one client-side engine

Start with geotag if you have a track. Fix the camera clock first if timestamps are wrong. Map what you already tagged, or audit and strip location before you publish.

Geotag photos from a GPX track
Drop JPEGs and a GPX (or related track), set the camera→GPS offset, preview matched pins on a map, then download geotagged copies. Unmatched shots stay unmatched — never silently guessed.
Fix camera clock / timezone offset
The step that breaks geotagging when travel or drift skews the camera clock. Shift DateTimeOriginal by ±h:m:s, or derive the delta from a photo of your GPS clock.
Strip GPS / location leak audit
Count how many photos carry GPS, see clusters within a radius you choose, then strip location from copies. Camera settings stay; originals are never overwritten.
Map a photo folder
For folders that already have GPS in EXIF — scrub the timeline, inspect the shoot, export for other maps. Pair with geotag when you still need coordinates from a track.

A typical trip · 03

Offset → geotag → check

Fix the camera clock if Date Taken does not match GPS time — especially after travel or long stretches without syncing the camera.
Geotag from your GPX track: preview pins, confirm unmatched shots, download copies with coordinates written into EXIF.
Map the folder to scrub the shoot, or strip GPS after an audit when you are about to publish and location would leak.

Privacy · 04

Nothing is uploaded

Photos and tracks are processed on your device (heavy work in a Web Worker so large batches stay responsive). There is no upload endpoint, no object storage, and no account. Originals are never modified in place — you always download copies or exports.

Map tiles are a separate network request for the basemap only. Your images never ride along.
