I have a GeoTIFF image, size 11gb. It's too big to work with. How can I compress it in JPEG format with QGIS? I tried through GDAL and did not succeed.

  • perhaps check this post regarding the correct GDAL usage: https://gis.stackexchange.com/questions/26249/how-to-convert-qgis-generated-tiff-images-into-jpg-jpeg-using-gdal-command-line – dmci Jan 26 '19 at 02:12

    TIFF can be compressed as well. Use this command gdal_translate -of GTiff -co tiled=yes -co compress=JPEG -co photometric=YCBCR input.tif output.tif and then create overviews with gdaladdo -r average -ro --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR 2 4 8 16 32 64. – user30184 Jan 28 '19 at 07:35
  • Please never just say but it didn't work or did not succeed, that will attract downvotes and close votes. Instead, edit your question and say what actually did happen. Was there an application/software crash, was there an error message (if so what was the complete error message as text, not screenshot), did the program run but produce incorrect/unexpected results (if so what were they)? And also, you need to edit your question and provide a gdalinfo or QGIS layer Properties->Information report for your TIFF, as currently we don't have enough informationto actually answer. – user2856 Jul 25 '19 at 21:05

Try to use BigTIFF in your operation.

BIGTIFF=YES

gdal_translate -co BIGTIFF=YES -co compress=JPEG input.tif output.tif

it would help if you amended your quesiton to show us your GDAL script.

A simply go to Raster/Conversion/Translate. Then in the Converted field go to "..." - Save to file, Choose: JPG or JP2
