# tools.image.maxBytes

Part of [Tools](https://kernstra.com/docs/web-sdk/config/tools) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `number`
- Default: `10 MB`
- Page: https://kernstra.com/docs/web-sdk/config/tools/image-maxbytes

The largest file accepted, in bytes. Whatever its size, an image whose header claims over 64 million pixels, or a side over 16384 px, is refused before it is decoded. A value that is not a positive number keeps the default.
