What is in this file

52,743 numbered lines of plain English text, each prefixed with its line number and starting byte offset so truncation is easy to spot. A closing rule of "=" characters brings the file to the exact size.

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:

SystemLimitNote
PHP2 MB per uploaded file by default (upload_max_filesize)A 5 MB upload fails on an untuned PHP installation.
Vercel Functions4.5 MB request bodyLarger uploads must go directly to object storage.
Amazon S3 multipart upload5 MiB minimum part sizeThis file is exactly one minimum part.
AWS Lambda6 MB synchronous invocation payload5 MB of binary data exceeds it once base64-encoded.
Browser localStorageAbout 5 MB per originStoring this file as text fills the quota.
Django2.5 MB in memory by defaultLarger uploads are streamed to a temporary file instead of held in memory.

All 5 MB sample files

Use this file for

  • Simulating photo uploads from phones
  • Baseline upload and download tests
  • Checking encoding handling

Testing notes for TXT

  • An empty or whitespace-only file is still a valid text file and is worth a test of its own.
  • Plain text compresses very well, so a 10 MB text file may travel as a fraction of that when gzip or Brotli is enabled. Use the BIN samples when you need incompressible bytes.
