MinerU HTML
SLM-powered HTML main content extractor for RAG and agent pipelines.
MinerU HTML is a solid free tool for cleaning up messy web pages when you need to preserve code, formulas, and tables. It's manual — you upload files one at a time — so it's not for automated pipelines. For one-off cleanups, it beats Trafilatura on structured content. But if you need API access or batch processing, look at Firecrawl or Apify.

Skip MinerU HTML if you need to automate extraction at scale, require API or batch processing, or need to crawl the web — you'll need a scraper with API access like Firecrawl or Apify.
MinerU HTML is completely free, which is ideal for individual developers and researchers who need occasional, high-quality HTML extraction. It has no cost advantage over cheaper peers like Trafilatura, which is also open-source, but it lacks the API and scalability of paid tools like Firecrawl.
In short
MinerU HTML — SLM-powered HTML main content extractor for RAG and agent pipelines. Best for Deep research agent developers needing clean extracts from forums or docs, RAG pipeline engineers who need high-fidelity HTML bodies, ML researchers requiring clean training data from diverse web sources. Free to use.

About MinerU HTML
MinerU HTML is a specialized web extraction tool that uses small language models (SLMs) to convert messy, complex HTML pages into clean, structured markdown. It's designed for developers building deep research agents, RAG pipelines, or training datasets. The tool excels at preserving code blocks, math formulas, tables, and other structural elements that generic scrapers often lose. You upload a single HTML file through the web interface and get real-time, high-fidelity markdown output. It's free to use, but it's manual — there's no API or batch processing. This tool is part of the AICC dataset ecosystem, making it a reliable choice for data engineers, ML researchers, and developers who need accurate extraction from diverse web sources, especially where technical content matters.
Behind the Verdict
MinerU HTML fills a niche for developers who need high-fidelity extraction from complex HTML pages. Its SLM-based approach sets it apart from regex-based scrapers, as it understands page layout and content hierarchy, not just tags. This means it can handle forums, Q&A sites, and ad-heavy pages while preserving code blocks with syntax, LaTeX formulas, and complex tables — features that matter for RAG and training data. The tool is free, but it's limited to manual, one-at-a-time processing via the web interface. There's no API, no batch mode, and no crawling — you must already have the HTML files. This makes it a great fit for researchers or developers doing occasional cleanup, but not for production pipelines. If you need automation, tools like Firecrawl, Apify, or Trafilatura (with its simpler extraction) are better. The lack of visual rendering is also a drawback if you need to verify layout, but since the output is markdown, that's not a core need. Overall, MinerU HTML is a practical, focused tool for its intended use case, with no cost barrier to trying it.

Real-world workflow fit
Concrete scenarios for the personas MinerU HTML actually fits — and what changes day-one when you adopt it.
You have a folder of saved HTML files from Common Crawl, many with ads and complex layouts. Use MinerU HTML to upload each file and get clean markdown, preserving code and tables, to build a high-quality training dataset.
Outcome: You obtain clean, structured markdown for dozens of pages, ready for further processing, without writing custom parsing scripts.
You've scraped documentation pages into HTML files. With MinerU HTML, you extract the main content, stripping navigation and ads, and convert to markdown for chunking and indexing.
Outcome: Your RAG pipeline now receives cleaner, more focused text, improving retrieval accuracy and reducing noise.
You've saved HTML pages with math formulas from various sites. MinerU HTML extracts LaTeX and preserves table structures, making the data usable for training a math-aware model.
Outcome: You get accurate formula and table representations without manual transcription, saving days of work.
Use Cases
- Extract clean HTML from messy Common Crawl pages for LLM training
- Preprocess web content for retrieval-augmented generation pipelines
- Generate training data from forum and Q&A pages preserving code blocks
- Clean up HTML from ad-heavy sites for research datasets
- Extract structured tables and formulas from scientific web pages
Models Under the Hood
as of 2026-09-01
Limitations
- The tool processes single HTML files via an online interface and outputs markdown.
- There's no API or batch processing, so you can't automate extraction.
- It doesn't render pages visually, so you can't see the original layout.
- It requires you to have HTML files already; it doesn't crawl the web.
- It's free, but that means no support guarantees.
- For large-scale projects, you'll need a different solution.

Featured Head-to-Head Comparisons
Mineru Html vs Geologicai
GeologicAI and MinerU HTML serve completely different domains and are not direct competitors. If you're in mining exploration requiring rapid core scanning and AI modeling, GeologicAI is the only choice—its recent $44M funding and Lumo acquisition strengthen its sensor suite. For developers needing high-fidelity HTML extraction for RAG or training data, MinerU HTML is free and effective. No substitution possible; choose based on your industry.
Mineru Html vs Versatile
Versatile and MinerU HTML are incomparable—one is a physical hardware solution for crane operations in steel erection, the other a free software tool for extracting clean HTML from complex web pages. Choose Versatile if you manage tower/crawler cranes and need passive real-time data; choose MinerU HTML if you build RAG systems or train models and need high-fidelity web content extraction.
Mineru Html vs Screenplayiq
If you need data-driven feedback on your feature film script's marketability and box office potential, ScreenplayIQ is your tool. But if you're a developer building RAG pipelines or training ML models and need clean HTML bodies from messy web pages, MinerU HTML is the free, specialized choice. No overlap — pick based on your domain.
