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

The first 64 bytes of sample-tiff-5mb.tiff as a hex dump: offset, bytes, then the same bytes as text. The TIFF signature is 49 49 2A 00.

Where 5 MB matters

A 5,242,880-byte file: the size of a phone photo and the minimum part size for S3 multipart uploads. These are the default limits a file of this size is useful for testing:

System	Limit	Note
PHP	2 MB per uploaded file by default (upload_max_filesize)	A 5 MB upload fails on an untuned PHP installation.
Vercel Functions	4.5 MB request body	Larger uploads must go directly to object storage.
Amazon S3 multipart upload	5 MiB minimum part size	This file is exactly one minimum part.
AWS Lambda	6 MB synchronous invocation payload	5 MB of binary data exceeds it once base64-encoded.
Browser localStorage	About 5 MB per origin	Storing this file as text fills the quota.
Django	2.5 MB in memory by default	Larger uploads are streamed to a temporary file instead of held in memory.

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.

Verify your copy

This file is created in your browser, so it has no direct URL for curl or wget. The bytes are the same every time and in every browser, so after saving it you can compare its checksum with the SHA-256 value above.

sha256sum sample-tiff-5mb.tiff     # Linux
shasum -a 256 sample-tiff-5mb.tiff # macOS

On Windows, run Get-FileHash sample-tiff-5mb.tiff -Algorithm SHA256 in PowerShell. For scripts and pipelines, save the file once and keep your own copy, or use a 1 MB file, which has a direct URL.

Questions about this file

Is this file exactly 5 MB?: Yes. It is 5,242,880 bytes, which is 5 MB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
What is inside the 5 MB TIFF file?: An uncompressed 1526 × 1145 test card in a single strip, after one image file directory of 14 tags. 778 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.
