What is a GeoTIFF?
A GeoTIFF is a TIFF raster image with embedded georeferencing metadata. Where an ordinary TIFF is just a grid of pixels, a GeoTIFF also stores the affine transform that places each pixel in real-world coordinates, the coordinate reference system (CRS), and parameters describing the projection. That extra metadata is what lets a GeoTIFF be overlaid on a map, compared to other geospatial layers, or analysed alongside vector data.
GeoTIFFs are the dominant raster format in geospatial analysis: every major satellite program (Sentinel-2, Landsat, NAIP, MODIS), every elevation source (SRTM, ASTER, USGS DEMs), and most land-cover and classification products distribute their data as GeoTIFFs. Cloud-Optimized GeoTIFFs (COGs) are a modern variant that allows efficient HTTP-range streaming for cloud-native workflows.
Common uses for an online GeoTIFF viewer
Previewing satellite downloads
Quickly check a Sentinel-2, Landsat, or NAIP scene you just downloaded without spinning up QGIS — make sure the right area was captured and the bands look correct.
Validating elevation data
Drop a DEM or SRTM tile to confirm the coverage and visually scan for nodata holes or seams before bringing it into your analysis pipeline.
Checking client deliverables
When a contractor sends you orthophotos or classified rasters, view them directly in the browser to confirm CRS and coverage before importing into ArcGIS or QGIS.
Sharing imagery without software
Send a colleague a GeoTIFF plus a link to this viewer and they can see the data on a map — no GIS install required.
How to view a GeoTIFF file
- Drag your
.tifor.tifffile onto the viewer above, or click to browse. - The raster is decoded in your browser and rendered on an interactive map.
- Metadata — CRS, dimensions, bands, pixel size, bounding box — appears alongside the image.
- Pan and zoom to explore. For multi-band rasters, you can preview the first three bands as an RGB composite.
All decoding is client-side via WebAssembly. Your file is never uploaded to a server — safe for sensitive imagery, internal datasets, or anything you would not paste into a third-party API.
What the viewer reports about your GeoTIFF
Coordinate Reference System
EPSG code (where embedded), projection name, and datum.
Dimensions
Width × height in pixels and the pixel resolution in CRS units.
Bands
Number of bands, sample format (uint8, float32, etc.), and band statistics.
Bounding Box
Geographic extent of the image, useful for cropping or mosaicking.
Affine Transform
The 6-parameter transform that maps pixel coords to world coords.
Compression
Compression method (LZW, Deflate, JPEG, none) and whether it is a COG.
Frequently Asked Questions
How do I view a GeoTIFF file online?
Drag and drop your .tif or .tiff file onto the viewer above, or click to browse. The raster is decoded in your browser and rendered on an interactive map. No QGIS, no ArcGIS, no upload — your file stays on your device.
What types of GeoTIFF files does this viewer support?
Single-band and multi-band GeoTIFFs, including satellite imagery (Sentinel-2, Landsat, NAIP), digital elevation models, land-cover classifications, and any other georeferenced raster. Cloud-Optimized GeoTIFFs (COGs) work as well.
Is my GeoTIFF data uploaded to a server?
No. The file is decoded by WebAssembly inside your browser tab. Nothing is uploaded to QuickMapTools. Safe for sensitive imagery, in-progress survey data, or anything internal.
How large a GeoTIFF can I view?
Browser memory is the limit — typically a few hundred MB will load comfortably on a modern laptop. For multi-gigabyte rasters, consider using the GeoTIFF cropper to clip to your area of interest first, or convert to a Cloud-Optimized GeoTIFF (COG) which streams more efficiently.
Can I check the projection (CRS) of my GeoTIFF?
Yes. The viewer reads the embedded GeoTIFF tags and reports the CRS (EPSG code where available), pixel resolution, bounding box, and number of bands. If you need to reproject, use our reproject-geotiff tool.
How is a GeoTIFF different from a regular TIFF?
A GeoTIFF is a TIFF image with extra metadata that georeferences each pixel to real-world coordinates — typically the affine transform, CRS, and projection parameters. A regular TIFF has no spatial information; a GeoTIFF can be overlaid on a map.
What can I do with a GeoTIFF after viewing it?
Use our raster tools to crop to a smaller AOI, reproject to a different CRS, resize, extract individual bands, or split a multi-band raster into separate files. The Raster Workflow Builder (Pro) lets you chain these into one pipeline.
GeoTIFF files are georeferenced rasters that cannot be viewed in a standard image viewer — viewing the file here renders the raster on a map with correct spatial positioning, showing pixel values and metadata alongside the image.
