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 automated batch extraction via API, visual page rendering, or if you expect to process thousands of pages without manual uploads — it's a manual single-file tool.
The pricing is ideal for individuals or small teams needing occasional cleanups without budget constraints — it's free. For heavy pipeline use, Firecrawl offers paid API access (around $19/mo) with automation, while Trafilatura is open-source but less accurate on structured content.
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.

- +Community calls it the industry benchmark for single-document HTML extraction fidelity
- +Preserves code blocks, math formulas, and complex tables that generic scrapers usually lose
- +Handles forum, Q&A, and ad-heavy pages where naive extractors fail
- +Outputs clean markdown that people describe as genuinely good in real tests
- +Free web playground makes it easy to try without any signup friction
- −Inference is slow on long HTML — users say it can't meet industrial throughput
- −No API and no batch mode means everything is one file at a time, manually
- −Large HTML files reportedly crash the runtime on modest GPU setups like Kaggle
- −VLM occasionally misclassifies sidebar and spam nodes as main content on some sites
- −The scalable clustering / xPath-distillation pipeline from the AICC paper isn't open-sourced
- • No monetary cost, but throughput cost is real: manual, one-file-at-a-time extraction eats engineering time
- • Running the open-source model locally requires GPU capacity, which has its own cloud spend
- • Adopting the full AICC pipeline for scale is not free of effort — parts aren't open-sourced

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. You upload a single HTML file through the web interface and get real-time, high-fidelity markdown output. 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. 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 stands out for its SLM-based semantic understanding, which goes beyond simple text extraction to preserve the structural integrity of code blocks, math formulas, and tables. This makes it particularly valuable for technical content, forums, and scientific pages where generic scrapers lose fidelity. The tool is free to use, which is a major plus for developers who need occasional cleanups without a subscription. However, it operates only as a manual web interface for single HTML files — there's no API, batch processing, or crawling capability. This limits its use to one-off tasks or evaluation phases. For automated pipelines, you'll need to look elsewhere, such as Firecrawl or Apify, which offer API-driven extraction. If your needs are occasional and you value high-quality extraction of technical content, MinerU HTML is worth trying. But if you require scale, automation, or visual rendering, it's not the right fit.

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 downloaded HTML file from Common Crawl that contains ads and boilerplate. You upload it to MinerU HTML and receive clean markdown preserving any tables or code snippets.
Outcome: Within minutes, you get a high-fidelity training sample ready for your LLM dataset pipeline.
You need to extract the main content from a technical documentation page for your RAG pipeline. You save the HTML and upload it to MinerU HTML.
Outcome: You obtain a clean markdown version with code blocks intact, ready to be chunked and embedded.
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.

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.
