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:
| System | Limit | Note |
|---|---|---|
| Browser cookies | 4,096 bytes per cookie | 5 KB does not fit in one cookie. |
| Vite asset inlining | 4 KB by default (assetsInlineLimit) | A 5 KB asset is emitted as a separate file rather than inlined as base64. |
| nginx and Apache request headers | 8 KB per header line by default | 5 KB fits; the 10 KB sample does not. |
Use this file for
- Checking thumbnail and icon handling
- Testing avatar and reaction uploads
- Testing whether image pipelines preserve animation
Testing notes for GIF
- Many resizing libraries silently keep only the first frame of an animated GIF.
- Animated GIFs are large for what they show; a few seconds can reach several megabytes, so they hit size limits early.
