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
- Verifying text extraction and page counts
- Exercising virus scanning and content inspection
Testing notes for PDF
- A file cut off before its final "%%EOF" marker usually cannot be opened, which makes PDF a good format for detecting truncated transfers.
- PDFs can embed JavaScript and attachments, so upload handlers should scan them rather than trust the extension. The samples here contain neither.
