marker vs PaddleOCR
Document conversion and OCR toolkits compared
marker converts PDFs and other supported documents into structured formats such as Markdown, JSON, HTML, and chunks. PaddleOCR provides OCR and document-parsing pipelines for images and PDFs, with broader capabilities for multilingual recognition, translation, and information extraction.
marker: Convert Documents into Structured Text
Marker converts PDFs and other documents into Markdown, JSON, HTML, or chunks, preserving structure such as tables, equations, and images. It suits developers building document-processing workflows who can run its local models and inference backend.
PaddleOCR: Extract Text and Structure from Images and PDFs
PaddleOCR is a Python toolkit for recognizing text and parsing document layouts in images and PDFs. It suits developers building OCR, document-processing, and retrieval workflows who need structured output and multilingual recognition.

Key differences
- marker focuses on converting documents into several output formats; PaddleOCR spans text recognition, document parsing, translation, and information extraction.
- marker combines text-layer extraction, layout detection, OCR, and selective vision-language model use; PaddleOCR offers distinct model families and pipelines for recognition and parsing.
- marker supports additional formats such as DOCX, XLSX, PPTX, HTML, and EPUB with dependencies; PaddleOCR centers on images and PDFs.
- marker lists a local inference server and a small-scale API server, with vLLM or llama.cpp options; PaddleOCR lists CPU and accelerator inference, plus ONNX Runtime and OpenVINO deployment options.
- Both are Python projects under Apache-2.0, while marker notes that its model weights have separate modified OpenRAIL-M terms.
- PaddleOCR has 90.6k stars and 11.4k forks, compared with marker's 40.2k stars and 2.9k forks.
Choose marker if you…
- need to convert documents into Markdown, JSON, HTML, or chunks for downstream workflows.
- want a local conversion pipeline with customizable processors, renderers, or providers.
- work mainly with PDFs and need to preserve elements such as tables, equations, code, links, and images.
Choose PaddleOCR if you…
- need OCR for images or documents across more than 100 languages.
- want selectable pipelines for text recognition, document parsing, translation, or information extraction.
- need deployment options that include CPU, accelerators, ONNX Runtime, or OpenVINO.
