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:

SystemLimitNote
nginx1 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 multipart1 MB per file by default (max-file-size)A file of exactly 1 MB is at the limit.
Next.js API routes and Server Actions1 MB by defaultLarger bodies need the size limit raised in configuration.
Cloud Firestore documents1 MiB (1,048,576 bytes)The same number of bytes as this file.
Apache Kafka messagesAbout 1 MB by defaultBrokers reject larger records unless message.max.bytes is raised.

All 1 MB sample files

Use this file for

  • Finding the first upload limit in a new stack
  • Testing map imports and layer rendering
  • Checking conversion between KML, GPX and GeoJSON

Testing notes for KML

  • KML can pull in remote content through network links and icon URLs. An importer should not fetch them blindly. The samples here refer to nothing outside the file.
  • Longitude comes first. Reading the pair the other way round moves every point to a different part of the world.
