How It Works
Upload Photos
Drag and drop or browse for multiple JPEG, PNG, or WebP images at once.
EXIF Auto-Extract
GPS coordinates, date, altitude, and camera info are read from each photo's metadata.
Address Lookup
Coordinates are reverse-geocoded to human-readable addresses via OpenStreetMap.
Download Stamped
Each photo gets a professional overlay stamp. Download individually or all at once.
Frequently Asked Questions
What is EXIF GPS data?
EXIF (Exchangeable Image File Format) is metadata embedded in photos by your camera or phone. When location services are enabled, the GPS coordinates, altitude, date, and camera model are stored in the image file. This tool reads that data and uses it to create a visible stamp.
Are my photos uploaded to a server?
No. All processing happens entirely in your web browser using JavaScript and the HTML5 Canvas API. Your photos never leave your device. We do not store, transmit, or have access to any of your images.
What if my photo does not have GPS data?
If a photo lacks embedded GPS coordinates, the tool will flag it and give you the option to manually enter latitude and longitude values. The stamp will then be applied with the coordinates you provide.
Which image formats are supported?
The batch stamp tool supports JPEG, PNG, and WebP images. JPEG files are most likely to contain EXIF GPS data since it is the standard format for camera and smartphone photos.
How does the address lookup work?
The tool uses the OpenStreetMap Nominatim API to convert GPS coordinates into a human-readable address (reverse geocoding). This is the same service used by many open-source mapping applications. There is a small delay between requests to respect their usage policy.
Can I customize what information appears on the stamp?
Yes. The settings panel lets you toggle each data field on or off: timestamp, GPS coordinates, altitude, address, and the GPSnap badge. You can also choose between small, medium, or large font sizes and whether the overlay appears at the top or bottom of the image.
Is there a limit on how many photos I can process?
There is no hard limit. However, since all processing happens in your browser, very large batches (hundreds of high-resolution images) may slow down depending on your device. We recommend processing in batches of 20-50 images for the best experience.
What is the output format and quality?
Stamped images are exported as JPEG files at 92% quality. The output resolution matches the original photo resolution, so you do not lose any detail.
