Add a Timestamp and GPS Location to Photos Online (Free, Private)

A date proves when. A location proves where. Together they turn an ordinary photo into usable evidence — for an insurance adjuster, a tenancy tribunal, a project manager, or your own records. This guide shows how to overlay both a timestamp and a GPS location stamp onto photos online, free, without uploading them anywhere. If your phone recorded GPS coordinates when the photo was taken, the tool reads them automatically; if not, you can set the location yourself on a map.

Where the Location Data Comes From

Modern phones embed GPS coordinates in each photo's EXIF metadata at capture time (when location services are enabled for the camera). iPhotoStamp reads that embedded data directly in your browser and can render it on the photo as: • **Decimal coordinates** — 25.276987, 55.296249 — compact and unambiguous • **DMS format** — 25°16'37"N 55°17'46"E — the traditional surveying style • **A small map thumbnail** — a rendered map snippet showing the capture point, placed alongside the stamp Because the coordinates come from the photo's own metadata, the location stamp reflects where the photo was actually taken — not where you happened to be when you processed it.

When Photos Have No GPS Data

Screenshots, photos shared through WhatsApp or email, and images from cameras without GPS typically carry no location metadata. For those, the tool provides a map picker: search or click the location, and it applies to the photo (or the whole selected batch). The stamp is styled identically either way.

Adding Both Stamps in One Pass

Date and location are independent layers with independent styling. A typical evidence-grade setup places the timestamp in the bottom-right and the GPS stamp in the bottom-left, each with a translucent background chip for legibility. Both are configured once and applied to the entire batch: 1. Load your photos — EXIF date and GPS are read automatically, with badges showing what was found 2. Enable the **Date** stamp and choose its format and corner 3. Enable the **GPS** stamp, pick decimal or DMS, and optionally switch on the map thumbnail 4. Export as ZIP, PDF, or individual JPGs The result is a set of photos that each answer both questions — when, and where — at a glance, with the originals untouched on your device.

Privacy: Location Data Deserves Extra Care

GPS metadata is among the most sensitive data your photos carry — it can map your home, your movements, and your habits. That makes the upload question sharper here than anywhere else: a server-based tool that processes geotagged photos receives not just your images but your location history. iPhotoStamp processes EXIF and GPS data entirely client-side. The coordinates are read, rendered, and burned into the output image by your own browser. Nothing — not the photo, not the metadata, not the map lookup for your stamp — is sent to iPhotoStamp servers, because there are none in the processing path.

Who Needs Location-Stamped Photos

• **Field engineers and surveyors** — tying each defect or measurement photo to an exact position on a large site • **Insurance documentation** — proving damage photos were taken at the insured property, not somewhere else • **Property inspections** — anchoring move-in/move-out evidence to the actual address • **Delivery and logistics** — proof-of-location for completed drops • **Agriculture and environment** — recording where each field observation was made In each case the visible stamp does what raw EXIF cannot: it survives screenshots, prints, and re-saves, and it is readable by any human looking at the image.

Conclusion

Location turns a dated photo into a placed, dated record. With EXIF GPS reading, DMS and decimal formats, an optional map thumbnail, and fully client-side processing, iPhotoStamp adds both stamps in a single batch pass — free, private, and accurate to the photo's own metadata. Load a geotagged set and check the badges: the where and the when are already in your photos, waiting to be made visible.
