如何查看 GEOTIFF、COG、TIFF 文件

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.

Para qué sirve

  • 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.

Compatibilidad y limitaciones

  • 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

Preguntas frecuentes

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?
