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 500 KB matters

A 512,000-byte file: larger than most API body limits, smaller than most upload limits. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Amazon DynamoDB items	400 KB per item	500 KB cannot be stored as a single item.
Express body parsers	100 KB by default	Rejected unless the limit is raised.
nginx request body	1 MB by default (client_max_body_size)	Accepted with room to spare.

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.
