Where 5 MB matters
A 5,242,880-byte file: the size of a phone photo and the minimum part size for S3 multipart uploads. 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 5 MB upload fails on an untuned PHP installation. |
| Vercel Functions | 4.5 MB request body | Larger uploads must go directly to object storage. |
| Amazon S3 multipart upload | 5 MiB minimum part size | This file is exactly one minimum part. |
| AWS Lambda | 6 MB synchronous invocation payload | 5 MB of binary data exceeds it once base64-encoded. |
| Browser localStorage | About 5 MB per origin | Storing this file as text fills the quota. |
| Django | 2.5 MB in memory by default | Larger uploads are streamed to a temporary file instead of held in memory. |
Use this file for
- Finding the first upload limit in a new stack
- Testing document uploads in public-sector and education software, where ODT is often mandatory
- Checking conversion between ODT, DOCX and PDF
Testing notes for ODT
- Layout rarely survives a round trip through Word unchanged: fonts, numbering and tables are the usual casualties.
- Reading the type from the mimetype entry only works if that entry comes first and is not compressed. Tools that re-zip a document tend to break both rules, and strict readers then reject the file.
