Free GeoTIFF Viewer Online

Drop a .tif file below and view it instantly — parsed entirely in your browser, never uploaded to a server. No login, no software installation.

Need to keep this layer, stream large COGs, or overlay Sentinel imagery?

TL;DR: View GeoTIFF files online for free using the drag-and-drop viewer above — files are parsed 100% client-side in your browser and never uploaded. UTM and other common projections are reprojected automatically. For COG streaming, multi-band RGB composites, GeoJSON, and satellite imagery overlays, use the free Off-Nadir Delta workspace.

COG Support

Cloud Optimized GeoTIFF enables streaming for large files without downloading entirely.

Multi-Band Display

Select bands, create RGB composites, and apply custom color ramps.

Layer Integration

Combine your data with Sentinel imagery in a single view.

How It Works

Drop Your GeoTIFF

Drag and drop a .tif file onto the viewer above, or click to browse. No account needed.

View Instantly

The file is parsed in your browser and displayed on the map — it never leaves your device.

Inspect & Adjust

Zoom to your data, check the extent and dimensions, and adjust layer opacity.

Analyze in the Workspace

Create a free account to save layers, build RGB composites from multi-band rasters, and overlay Sentinel imagery.

Frequently Asked Questions

Is my GeoTIFF uploaded to a server?▼

No. The viewer on this page parses your file entirely in your browser using client-side processing — the file never leaves your device. Saving layers for later requires a free account.

What GeoTIFF formats are supported?▼

Standard GeoTIFF and Cloud Optimized GeoTIFF (COG). COG format is recommended for large files as it enables streaming and progressive loading in the workspace.

What is the maximum file size?▼

The free in-browser viewer on this page handles files up to 150MB, limited by browser memory. In the workspace, size limits depend on your plan, and COG streaming works best for large rasters.

What coordinate systems are supported?▼

Most common projections including WGS84 (EPSG:4326), Web Mercator (EPSG:3857), and UTM zones (WGS84, NAD27, NAD83). Files are automatically reprojected for display.

Can I view multi-band rasters?▼

Yes. The on-page viewer renders the first three bands as RGB (or grayscale for single-band data). In the workspace you can select bands and create custom RGB composites.

How long are uploaded files stored?▼

Files viewed on this page are never stored — everything happens locally. In the workspace, saved layers are stored according to your plan and can be managed from the Layer Manager.
