Where 1 MB matters
A 1,048,576-byte file: exactly the default upload limit of nginx, Spring Boot and Next.js. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| nginx | 1 MB by default (client_max_body_size) | A multipart upload of this file exceeds the limit by the size of the form boundaries. |
| Spring Boot multipart | 1 MB per file by default (max-file-size) | A file of exactly 1 MB is at the limit. |
| Next.js API routes and Server Actions | 1 MB by default | Larger bodies need the size limit raised in configuration. |
| Cloud Firestore documents | 1 MiB (1,048,576 bytes) | The same number of bytes as this file. |
| Apache Kafka messages | About 1 MB by default | Brokers reject larger records unless message.max.bytes is raised. |
Use this file for
- Finding the first upload limit in a new stack
- Testing import features that accept more than one delimiter
- Checking delimiter detection
Testing notes for TSV
- Windows does not open .tsv in Excel by default, so users rename files to .txt or .csv, and the extension stops describing the content.
- A field cannot contain a tab or a line break. Exporters deal with that in incompatible ways: some write backslash escapes such as \t, some apply CSV-style quotation marks, and some corrupt the row.
