BigTiff

The TIFF file has 64-bit offsets (instead of 32) allowing for bigger size images.

Reproducibility

Simulate

A BigTIFF file can be simulated by manipulating its header. Open the TIFF file with an Hexadecimal Editor (e.g. HxD)

  1. Change the bytes 2-3 to the decimal value 43 (2B in hexadecimal).
  2. Note that if the first two bytes of the TIFF file have the value 4D4D it means little endian, therefore 43 is 002B, and if the two first bytes are 4949 it means big endian and therefore 43 is 2B00.

Generate

BigTIFF files may be generated with editors that are able to write in this format.
