Where 10 MB matters
A 10,485,760-byte file: over the default limits of PHP, API Gateway and Spring Boot requests. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Amazon API Gateway | 10 MB payload | A 10 MB file in a multipart or base64 body is over the limit. |
| Spring Boot multipart | 10 MB per request by default (max-request-size) | Exceeded once form overhead is added. |
| PHP | 8 MB POST body by default (post_max_size) | Rejected before the script runs. |
| Amazon S3 multipart upload | 5 MiB minimum part size | This file splits into exactly two minimum-sized parts. |
| Email attachments | Commonly 20 to 25 MB per message | 10 MB fits, at about 13.3 MB once encoded. |
Use this file for
- Exercising chunked and resumable uploads
- Checking in-browser PDF previews
- Verifying text extraction and page counts
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.
