Mappero Geotagger review
Open-source desktop geotagging with GPX/KML correlation and map-based editing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Mappero Geotagger is an open-source desktop application for assigning, reviewing and saving geographic metadata on photographs. It suits solo and small-team users who want a map-based workflow across Windows, macOS and Linux. Photos can be dragged onto map markers, existing photo locations can be viewed, and location information can be written into image metadata for image types handled by exiv2.
Its standout capability is GPS-track correlation. The application displays GPX and KML tracks, then compares photo timestamps with track times to place images automatically. Timezone offsets and fine-grained timing adjustments help account for differences between camera clocks and GPS records. Map layers can be downloaded from OpenStreetMap and other providers, giving users a visual way to review placements before saving metadata. This combination makes it a practical choice for organizing travel, field or outdoor photo collections when track files are available.
Mappero Geotagger keeps its scope focused on desktop geotagging rather than a broader photo-management ecosystem. The latest listed release is version 1.10 from 2020, so buyers who prioritize a recently updated application may prefer an alternative. Support is offered through email and documentation, and deployment is limited to desktop platforms. Users seeking a cross-platform open-source tool with GPX/KML display, automatic timestamp matching and direct metadata writing should consider it; those needing mobile access, web collaboration or a wider integrated workflow should look elsewhere.
