What is in this file

A 477 × 357 lossless test card coded with literal pixels only, so the size is set by the pixel count. 972 bytes of XMP metadata, most of it standard whitespace padding, bring the file to the exact size.

Dimensions	477 × 357 px
Encoding	Lossless (VP8L)
Container	Extended (VP8X) with XMP metadata

Where 500 KB matters

A 512,000-byte file: larger than most API body limits, smaller than most upload limits. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Amazon DynamoDB items	400 KB per item	500 KB cannot be stored as a single item.
Express body parsers	100 KB by default	Rejected unless the limit is raised.
nginx request body	1 MB by default (client_max_body_size)	Accepted with room to spare.

All 500 KB sample files

Use this file for

Testing that APIs return 413 for oversized bodies
Testing whether upload forms accept modern formats
Checking conversion to and from JPEG and PNG

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.
