Where 5 KB matters

A 5,120-byte file: larger than a cookie, smaller than a typical HTTP header limit. These are the default limits a file of this size is useful for testing:

SystemLimitNote
Browser cookies4,096 bytes per cookie5 KB does not fit in one cookie.
Vite asset inlining4 KB by default (assetsInlineLimit)A 5 KB asset is emitted as a separate file rather than inlined as base64.
nginx and Apache request headers8 KB per header line by default5 KB fits; the 10 KB sample does not.

All 5 KB sample files

Use this file for

  • Smoke tests in CI that must run in milliseconds
  • Testing Markdown renderers and editors
  • Checking sanitisation of rendered HTML

Testing notes for Markdown

  • Markdown may contain raw HTML, so anything that renders user-supplied Markdown needs an HTML sanitiser.
  • Tables are an extension rather than part of CommonMark, so renderers differ on whether they appear.
