Where 25 KB matters
A 25,600-byte file: the size of a small web image or a short document. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| TCP initial congestion window | About 14.6 KB (10 segments) | 25 KB needs at least two flights of packets on a new connection. |
| Base64 encoding | Adds 33 percent | A 25 KB file becomes about 34 KB inside JSON or an email. |
Use this file for
- Checking thumbnail and icon handling
- Verifying upload filters that allow or block RTF
- Testing legacy document import
Testing notes for RTF
- Two MIME types are in use, application/rtf and text/rtf, and allow-lists should recognise both.
- RTF readers must skip groups they do not understand; a parser that fails on unknown control words is not conformant.
