 ## Utf8Parser
 
 [`Utf8Parser`](/developers/api-docs/pathway-xpacks-llm/parsers#pathway.xpacks.llm.parsers.Utf8Parser) is a simple parser designed to decode text encoded in UTF-8. It ensures that raw byte-encoded content is converted into a readable string format for further processing in a RAG pipeline.
 
 
+## PaddleOCR
+[`PaddleOCRParser`](/developers/api-docs/pathway-xpacks-llm/parsers/#pathway.xpacks.llm.parsers.PaddleOCRParser) is a parser that relies on the [PaddleOCR](https://aistudio.baidu.com/paddleocr) library.
+It requires the `paddlepaddle` package. The version depends on your hardware.
+If you want to run the OCR on CPU, you can install it with the following pip command: `pip install paddlepaddle>=3.2.0`
+For GPU support, follow the instructions on the [official site](https://www.paddlepaddle.org.cn/en/install/quick).
+
+The `PaddleOCRParser` uses a Paddle pipeline object to perform the parsing/OCR.
+Currently, `PaddleOCR` and `PPStructureV3` pipelines are supported.
+By default, it uses a `PPStructureV3` pipeline.
+
+More details on how to use the PaddleOCRParser in the [associated blog post](/blog/paddleocr/).

 ## UnstructuredParser
 
 [`UnstructuredParser`](/developers/api-docs/pathway-xpacks-llm/parsers#pathway.xpacks.llm.parsers.UnstructuredParser) leverages the parsing capabilities of [Unstructured](https://unstructured.io/). It supports various document types, including PDFs, HTML, Word documents, and [more](https://docs.unstructured.io/open-source/introduction/supported-file-types), making it a robust out-of-the-box solution for most use cases. Additionally, it offers good performance in terms of speed.
