TXT test files, any size.
Set a size and generate a structurally valid TXT immediately. Nothing is uploaded and nothing is stored.
TXT, built to spec.
Each file is a plain UTF-8 text file. The size you ask for is reached with printable ASCII characters, so the result opens in Notepad, TextEdit and VS Code. Most people generate these for the simplest possible upload and transfer test.

Questions.
How small can a TXT file be?
About 1 byte. Below that the format cannot carry its mandatory structure, let alone padding.
Will the file open normally?
Yes — it opens in Notepad, TextEdit and VS Code, because the padding lives in printable ASCII characters.
Can I ask for an unusual size?
Any byte count above the minimum works, including values like 3,145,728 or 27.5 MB. Drag the caliper or type the number.
