Where 200 KB matters

A 204,800-byte file: twice the default body limit of most API frameworks, and a common cap for photo and signature uploads on application forms. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Express body parsers	100 KB by default	Rejected with 413 unless the limit is raised.
Amazon DynamoDB items	400 KB per item	200 KB fits, even after base64 encoding takes it to about 273 KB.
Azure Service Bus, Standard tier	256 KB per message	Fits as raw bytes, but not once base64-encoded.

Checking email size handling
Testing avatar and reaction uploads
Testing whether image pipelines preserve animation

Testing notes for GIF

Animated GIFs are large for what they show; a few seconds can reach several megabytes, so they hit size limits early.
Many resizing libraries silently keep only the first frame of an animated GIF.
