What is in this file
A 213 × 159 lossless test card coded with literal pixels only, so the size is set by the pixel count. 638 bytes of XMP metadata, most of it standard whitespace padding, bring the file to the exact size.

Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |
Use this file for
- Checking email size handling
- Testing image CDNs and optimisation
- Testing whether upload forms accept modern formats
Testing notes for WebP
- Sniffers that read only the first four bytes see RIFF and may confuse WebP with WAV or AVI.
- Allow-lists written years ago often contain only JPEG, PNG and GIF, so WebP uploads fail on otherwise working forms.
