GPStamper "Know Where - Know When"

A Simple Workflow

A typical GPStamper [G-P-Stamper] photo includes subject description, coordinates (GPS or UTM), date/time and author (e.g. company/agency) information. Including an automatically generated location description, image direction, elevation, file name or other metadata, is optional.

Simply select a single geotagged (JPG) file or folder via drag-and-drop and click the Stamp Coordinates (globe) button for instant stamping of coordinates along with all selected content and appearance options. GPStamper is optimized to work best using drag-and-drop with Windows File Explorer. A file or folder can also be selected via GPStamper's main menu.

Stamping interface (with options hidden) is simple and efficient.

Subject Descriptions

  • A subject description entered into the Subject Description window is applied to all the photos in a selected folder.
  • A unique subject description for individual photos in a folder can be entered by ticking the checkbox left of the Subject Description window prior to stamping. The opportunity to assign a description to each photo will be given during stamping.
  • Alternatively, use File Explorer’s Details pane to add a unique subject description for each photo in a folder. Edit the Subject field, save changes, then leave the checkbox unticked and the Subject Description window in GPStamper empty.

Smart Clipboard

Use GPStamper's smart clipboard (right of the Subject Description window) to copy and paste subject description content from any Windows document, and write it directly to a file's metadata for stamping. The smart clipboard minimizes typing, and eliminates typos in complex technical/legal descriptions. Supports English (ASCII) characters.

How The Clipboard works...

  • If no description exists in the Subject Description window, click the clipboard (Clip) button to paste content copied from any Windows document and write it to the selected file or folder. The pasted description may be edited prior to being written and copied back to the clipboard.
  • Or, enter a subject description and click the Clip button to immediately write the metadata to the selected file or folder. The description is also copied to the clipboard.
  • GPStamper's Subject Description is written to File Explorer's "Subject" field. If no description exists in the Subject Description window, and the "unique descriptions" checkbox is not ticked, GPStamper uses the contents of File Explorer's "Subject" as the description during stamping.

Stamp appearance & content

Easily accessible font/appearance and content/formatting options can be hidden after selections are made. Selections are saved between stamping sessions.
All inputs and options have tooltips which describe their function.

Including subject and author (copyright) information is possible with all stamping options. Author (copyright) information, once entered, is saved from session to session.

Select from font size, color, opacity, placement and background/border options. "Auto" color converts font color from white to black, based on image brightness, automatically optimizing stamp contrast and legibility.

Available Content options:

  • Include AutoLocation (city, state/province, country, OR a high precision location)
  • Select coordinate notation as GPS (sexagesimal or decimal) or UTM
  • Include file name
  • Include horizontal positioning error or DOP (if present in photo metadata)
  • Include image direction (if present in photo metadata)
  • Include elevation (if present in photo metadata) and select units (feet or meters)
  • Include time (with date)
  • Include copyright © symbol
Option selections are saved between stamping sessions!


AutoLocations are location descriptions automatically derived by reverse geocoding a photo's GPS coordinates. Click the Stamp AutoLocation (GPS Pin) button for instant stamping of location descriptions along with all selected content and appearance options.

  • AutoLocation reports and stamps the closest city (population >1000) and state/province/municipality, with country being optional.
  • High precision locations which might include an actual point of interest name and/or street address are an option when stamping single JPG files. High precision locations may be edited prior to stamping.
GPStamper is designed for compatibility with Windows File Explorer, and saves all information to standard metadata tags.


Extract still frames from MOV or MP4 videos (including 4K) and instantly stamp them with location metadata just as you would still photos! Include coordinates, an AutoLocation, elevation (iPhone), date, time, subject description, and author information in the stamp.

An annotated and AutoLocated quad-frame photo extracted from a 25 second Samsung geotagged MP4 video.
  • A quad-frame photo is generated from four video frames spaced equidistant within the video clip, whereas a single-frame photo is generated from a single video frame located mid-point in the video clip.
  • Quad-frames are UHD (maximum), and single-frames are 1x the original video resolution.
  • All font options are available for use on video frames.

Google Earth

View photo locations in Google Earth via a single click! Display a single photo or an entire folder.

Click "Google Earth" in GPStamper's status bar to instantly display photo locations in Google Earth Pro (if installed). Click on camera icons to display thumbnail images.
  • Saving the generated KML file is optional. Use the KML file to easily create a map in Google My Maps, or generate a KMZ file (with bundled photos) in Google Earth.
  • Make sure that "Allow access to local files and personal data" is checked on Google Earth's "Tools > Options > General" tab if you wish to display thumbnails (as shown above).
  • Requires Google Earth Pro for Windows desktop, version 7.3.1 or later.

Geotagging photos

GPStamper can also geotag JPG/MOV/MP4 files from cameras lacking GPS by using a track log from any GPS device or mobile app (e.g. myTracks for iOS), readying the files for stamping.
