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
- Download tests on mobile connections
- Checking rasterisation to PNG
- Testing icon pipelines and optimisers
Testing notes for SVG
- SVG has no intrinsic byte-to-pixel relationship: a few hundred bytes can describe an image of any dimensions.
- An SVG shown with an <img> tag cannot run scripts, but the same file opened directly or inlined can. Sanitise uploads or serve them as attachments.
