What is in this file
A 1514 × 1153 test card. The pixel data sits in a deflate stream made of stored blocks, so the size is set by the pixel count. 4,338 bytes of tEXt comment chunk bring 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:
| 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. |
Use this file for
- Simulating photo uploads from phones
- Testing image uploads that must stay lossless
- Checking transparency handling
Testing notes for PNG
- Every chunk carries a CRC, so a strict decoder rejects a file that was altered in transit.
- PNG compresses flat colour extremely well, so a tiny file can expand to a very large bitmap. Check dimensions before decoding.

Questions about this file
- Is this file exactly 5 MB?
- Yes. It is 5,242,880 bytes, which is 5 MB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
- What is inside the 5 MB PNG file?
- A 1514 × 1153 test card. The pixel data sits in a deflate stream made of stored blocks, so the size is set by the pixel count. 4,338 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.
