What is in this file
A 682 × 512 lossless test card coded with literal pixels only, so the size is set by the pixel count. 862 bytes of XMP metadata, most of it standard whitespace padding, bring the file to the exact size.
| Dimensions | 682 × 512 px |
|---|---|
| Encoding | Lossless (VP8L) |
| Container | Extended (VP8X) with XMP metadata |

Where 1 MB matters
A 1,048,576-byte file: exactly the default upload limit of nginx, Spring Boot and Next.js. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| nginx | 1 MB by default (client_max_body_size) | A multipart upload of this file exceeds the limit by the size of the form boundaries. |
| Spring Boot multipart | 1 MB per file by default (max-file-size) | A file of exactly 1 MB is at the limit. |
| Next.js API routes and Server Actions | 1 MB by default | Larger bodies need the size limit raised in configuration. |
| Cloud Firestore documents | 1 MiB (1,048,576 bytes) | The same number of bytes as this file. |
| Apache Kafka messages | About 1 MB by default | Brokers reject larger records unless message.max.bytes is raised. |
Use this file for
- Download tests on mobile connections
- Checking conversion to and from JPEG and PNG
- Testing image CDNs and optimisation
Testing notes for WebP
- Sniffers that read only the first four bytes see RIFF and may confuse WebP with WAV or AVI.
- Allow-lists written years ago often contain only JPEG, PNG and GIF, so WebP uploads fail on otherwise working forms.
