What is in this file

An uncompressed 3761 × 2788 test card in a single strip, after one image file directory of 16 tags. 16 bytes of filler in the ImageDescription tag bring the file to the exact size.

Dimensions	3,761 × 2,788 px
Colour	8-bit RGB (24 bits per pixel)
Compression	None
Byte order	Little-endian (II)
Layout	One strip, one image directory
Resolution	72 dpi

First bytes of the file

Where 30 MB matters

A 31,457,280-byte file, 30 MB in the binary units that operating systems and upload limits use. It is useful wherever a form, an API gateway, a storage quota or a mail server is configured with a limit of about this size.

Testing image resizing and memory use
Testing image libraries with large uncompressed input
Verifying handling of both byte orders

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 30 MB?: Yes. It is 31,457,280 bytes, which is 30 MB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
What is inside the 30 MB TIFF file?: An uncompressed 3761 × 2788 test card in a single strip, after one image file directory of 16 tags. 16 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.
