How to inspect GEOTIFF, COG, TIFF files

GeoTIFF stores georeferencing with raster pixels, while COG optimizes tiled range access. Use this tool for inspection, not QGIS reprojection or raster analysis.

  1. Choose a .tif or .tiff file.
  2. Review dimensions, band count, geographic bounds, resolution, and NoData.
  3. Select RGB bands or a single-band color ramp.
  4. Read pixel values under the pointer and check orientation, stretch, and gaps.

What this tool helps with

  • Distinguish ordinary TIFF from geospatial raster
  • Quick band and geotag inspection
  • The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.

Compatibility and limitations

  • Not every EPSG definition is resolved and no reprojection is performed
  • Huge non-COG files can consume substantial memory
  • Display stretching is a preview, not quantitative remote-sensing analysis

Frequently asked questions

Can it open a normal TIFF?

It may display pixels, but reliable map bounds are unavailable without geotags.

Why is the image black?

16/32-bit data often needs a display stretch; choose the intended band and adjust min/max.

Is the raster uploaded?

The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
