Batch EXIF GPS Writer for JPEGs

About this tool

Drag and drop JPEG images, then batch-write EXIF GPS metadata from the latitude/longitude you provide (e.g., decimal "35.681236, 139.767125" or DMS "35°40'52.45" N, 139°46'01.65" E"). All processing happens in your browser (nothing is uploaded).

How to use

Drag and drop JPEGs or pick them with the “Add JPEGs” button.
Enter the coordinates you gathered (decimal example: 35.681236, 139.767125 / DMS example: 35°40'52.45" N, 139°46'01.65" E).
Adjust altitude, capture time, and overwrite settings if needed, then click “Write EXIF in batch and save ZIP.”

Notes

This tool does not call any map API—you fetch and enter the coordinates yourself.
DMS input may use N/S/E/W letters or ± signs.
If a file already has GPS data, the overwrite setting controls whether it is replaced.

Warnings

Only JPEG files are supported (PNG and others are not).
Large batches can consume significant browser memory.
Do not close the tab while processing.
