# Chunker node

> Configure a Chunker node to split partitioned document elements into chunks sized for embedding models, improving retrieval precision in RAG applications.

[Learn about the available chunking strategies](/concepts/chunking).

| [Chunk by Character](/api-reference/workflow/nodes/chunker/chunker-chunk-by-character)   | Combines elements within hard and soft character limits, without using section or page boundaries. |
| [Chunk by Title](/api-reference/workflow/nodes/chunker/chunker-chunk-by-title)           | Preserves section boundaries by starting a new chunk at each Title element.                        |
| [Chunk by Page](/api-reference/workflow/nodes/chunker/chunker-chunk-by-page)             | Preserves page boundaries, ensuring no chunk spans more than one page.                             |
| [Chunk by Similarity](/api-reference/workflow/nodes/chunker/chunker-chunk-by-similarity) | Groups topically similar consecutive elements into chunks using an embedding model.                |
