Where 500 KB matters
A 512,000-byte file: larger than most API body limits, smaller than most upload limits. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Amazon DynamoDB items | 400 KB per item | 500 KB cannot be stored as a single item. |
| Express body parsers | 100 KB by default | Rejected unless the limit is raised. |
| nginx request body | 1 MB by default (client_max_body_size) | Accepted with room to spare. |
Use this file for
- Testing that APIs return 413 for oversized bodies
- Measuring image optimisation
- Testing lazy loading and responsive images
Testing notes for JPG
- A small file can decode to a huge bitmap. Validate pixel dimensions as well as bytes, or a 5 MB upload can demand hundreds of megabytes of memory.
- Re-saving a JPEG loses quality each time, so pipelines should resize from the original.
