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
- Testing icon pipelines and optimisers
- Testing SVG sanitisation on upload
Testing notes for SVG
- An SVG shown with an <img> tag cannot run scripts, but the same file opened directly or inlined can. Sanitise uploads or serve them as attachments.
- SVG has no intrinsic byte-to-pixel relationship: a few hundred bytes can describe an image of any dimensions.
