What is in this file

An uncompressed 6840 × 5110 test card in a single strip, after one image file directory of 16 tags. 140 bytes of filler in the ImageDescription tag bring the file to the exact size.

Dimensions	6,840 × 5,110 px
Colour	8-bit RGB (24 bits per pixel)
Compression	None
Byte order	Little-endian (II)
Layout	One strip, one image directory

First bytes of the file

TIFF files cannot be shown in a browser. Download the file and open it in an application that reads TIFF, such as Adobe Photoshop and GIMP.

Where 100 MB matters

A 104,857,600-byte file: the request-body limit of Cloudflare's Free and Pro plans, and the size above which GitHub rejects a file outright.

Testing notes for TIFF

A TIFF may hold many pages. Code that reads only the first directory silently drops the rest of a scanned document.
Support for the compression schemes varies between libraries, so a file that opens in one tool can fail in another. The samples here are uncompressed, which every reader accepts.

Questions about this file

Is this file exactly 100 MB?: Yes. It is 104,857,600 bytes, which is 100 MB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
What is inside the 100 MB TIFF file?: An uncompressed 6840 × 5110 test card in a single strip, after one image file directory of 16 tags. 140 bytes of filler in the ImageDescription tag bring the file to the exact size.
Are the TIFF samples compressed?: No. They hold 8-bit RGB pixels with no compression, in a single strip, in little-endian byte order. That is the baseline form of the format.
