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 3 MB matters
A 3,145,728-byte file, 3 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.
Use this file for
- Finding the first upload limit in a new stack
- Testing uploads from scanners and document-capture systems
- Checking conversion to JPEG, PNG or PDF for display
Testing notes for TIFF
- 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.
- Chrome, Firefox and Edge do not display TIFF. An upload feature that previews images in the browser needs to convert TIFF on the server or show a placeholder.

Questions about this file
- Is this file exactly 3 MB?
- Yes. It is 3,145,728 bytes, which is 3 MB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
- What is inside the 3 MB TIFF file?
- An uncompressed 1182 × 887 test card in a single strip, after one image file directory of 16 tags. 166 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.
