What is in this file
A 299 × 227 test card. The pixel data sits in a deflate stream made of stored blocks, so the size is set by the pixel count. 871 bytes of tEXt comment chunk bring the file to the exact size.
| Dimensions | 299 × 227 px |
|---|---|
| Colour type | Truecolour RGB, 8 bits per channel |
| Transparency | No |

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. |
Use this file for
- Testing image compression targets
- Testing image optimisation and conversion
- Verifying dimension limits
Testing notes for PNG
- PNG compresses flat colour extremely well, so a tiny file can expand to a very large bitmap. Check dimensions before decoding.
- Converting a transparent PNG to JPEG needs a background colour; pipelines that forget produce black backgrounds.

Questions about this file
- Is this file exactly 200 KB?
- Yes. It is 204,800 bytes, which is 200 KB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
- What is inside the 200 KB PNG file?
- A 299 × 227 test card. The pixel data sits in a deflate stream made of stored blocks, so the size is set by the pixel count. 871 bytes of tEXt comment chunk bring the file to the exact size.
- Why are the sized PNG samples stored without compression?
- It makes the size exact and predictable: the pixel data is written in uncompressed deflate blocks, so byte count follows pixel count. The files are fully valid PNGs. For a normally compressed PNG, use the 1920 × 1080 test card.
