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 uploads from scanners and document-capture systems
- Checking conversion to JPEG, PNG or PDF for display
Testing notes for TIFF
- Support for the compression schemes varies between libraries, so a file that opens in one tool can fail in another. The samples here are uncompressed, which every reader accepts.
- Chrome, Firefox and Edge do not display TIFF. An upload feature that previews images in the browser needs to convert TIFF on the server or show a placeholder.
