Where 2 MB matters
A 2,097,152-byte file: exactly the default upload limit of PHP, and twice the default of nginx and Spring Boot. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| PHP | 2 MB per uploaded file by default (upload_max_filesize) | A file of exactly 2 MB is accepted; one byte more is refused. |
| nginx | 1 MB by default (client_max_body_size) | Rejected with 413 Request Entity Too Large. |
| Spring Boot multipart | 1 MB per file by default (max-file-size) | Rejected unless the property is raised. |
| Django | 2.5 MB in memory by default | 2 MB is held in memory; the 5 MB sample is streamed to a temporary file. |
| Vercel Functions | 4.5 MB request body | Accepted, including as base64 at about 2.8 MB. |
Use this file for
- Finding the first upload limit in a new stack
- Testing scrapers and HTML-to-text conversion
- Testing HTML sanitisers and upload filters
Testing notes for HTML
- Serve uploaded HTML with Content-Disposition: attachment or from a separate domain, and send X-Content-Type-Options: nosniff.
- A text file that merely starts with a tag can be sniffed as HTML by older browsers if the Content-Type header is missing.
