Open a raster, make the details visible, and prepare an image for your report. A focused viewer for a quick look, without setting up a full GIS project.

Open. Adjust. Export.
1
Open your GeoTIFF
Select or drop a .tif or .tiff file. Files stay in your browser; there is no file upload service.
2
Adjust the display
Choose RGB or grayscale and available bands. Use automatic contrast or set a minimum and maximum value.
3
Export an image
Save the entire rendered preview as JPG or PNG for a document or presentation. Keep the original GeoTIFF for geospatial work.
For a quick look, a clearer explanation, or a report
Check an unfamiliar raster
Inspect the image, dimensions, bands and available CRS before deciding how to process the original.
Understand a dark image
Try different bands and display ranges. An unexpected preview does not necessarily mean a damaged file.
Share a readable picture
Prepare a picture for someone who needs the visual, not a GIS dataset or specialist software.
A picture is not the original dataset
Exports contain the displayed colors at the preview resolution, not original bands, scientific values or georeferencing. This is a viewer, not a GIS editor, reprojection tool or satellite download catalog.
Questions before you open a file
What is a GeoTIFF, and how is it different from a TIFF?
GeoTIFF is a TIFF image with geographic metadata describing where the raster belongs. An ordinary TIFF need not include that information.
Why does my GeoTIFF look black in a photo viewer?
A photo viewer may not interpret specialized bands or value ranges as expected. Try the relevant band and automatic contrast. This adjusts the display; it does not repair damaged data.
Which files can I open?
This version reads the first image of supported grayscale and RGB TIFFs, including tested 8-bit, 16-bit, floating-point and Deflate examples. Limits: 128 MiB per file, 16 million source pixels, 96 MiB decoded data and 8 bands. Palette, rotated TIFF orientation and premultiplied-alpha files are not supported.
Will JPG or PNG keep the georeferencing?
No. These are ordinary rendered images, up to 1.2 million preview pixels with a 1536-pixel longest edge. Export saves the full preview, not just the visible zoomed area. Keep the source GeoTIFF for map placement or analysis.
Are my files uploaded or changed?
The viewer reads your chosen file locally in the browser and exports a new image. It does not upload file contents or overwrite the original. Loading this website and its example still requires network requests.
Can I use it instead of GIS software?
Use GIS software for editing, reprojection, spatial analysis and scientific measurement. This tool is designed for viewing, display adjustment and a simple image export.
