COG Dumper is a python utility to extract a tile from a Cloud Optimized GeoTIFF (COG) without decompressing the contained data. Tiff data can be hosted locally, on a web server or S3. This can be useful for serving compressed tiles from a TIFF without invoking Rasterio and GDAL. This utility has been tested with Tiff that have JPEG compression.
