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:

System	Limit	Note
PHP	2 MB per uploaded file by default (upload_max_filesize)	A 5 MB upload fails on an untuned PHP installation.
Vercel Functions	4.5 MB request body	Larger uploads must go directly to object storage.
Amazon S3 multipart upload	5 MiB minimum part size	This file is exactly one minimum part.
AWS Lambda	6 MB synchronous invocation payload	5 MB of binary data exceeds it once base64-encoded.
Browser localStorage	About 5 MB per origin	Storing this file as text fills the quota.
Django	2.5 MB in memory by default	Larger uploads are streamed to a temporary file instead of held in memory.

Simulating photo uploads from phones
Testing image CDNs and optimisation
Testing whether upload forms accept modern formats

Testing notes for WebP

Allow-lists written years ago often contain only JPEG, PNG and GIF, so WebP uploads fail on otherwise working forms.
Sniffers that read only the first four bytes see RIFF and may confuse WebP with WAV or AVI.
