LLM-Ready Markdown from Any Webpage

Power your RAG pipelines, AI agents, and content tools with structured Markdown extracted from any public URL.

Clean Content Extraction

Strips away navigation, footers, ads, and boilerplate to return only the meaningful content from any webpage.

Built for RAG Pipelines

Feed clean web content directly into vector stores and LLM contexts. Markdown reduces token consumption and eliminates preprocessing overhead.

Flexible Tag Filtering

Fine-tune the output by specifying which HTML tags to include or exclude. Get exactly the content your pipeline needs.

Scalable API

Process thousands of URLs programmatically with a single API call. Integrate with any language, framework, or agent orchestrator.

GitHub Flavored Markdown

Output includes GFM extensions — tables, task lists, strikethrough, and fenced code blocks — rendered perfectly in any Markdown viewer.

Lightning Fast

Results return in seconds. Our infrastructure is optimized for high throughput and low latency across global origins.

Built-in AI safety for untrusted webpages

Webpages can contain hidden instructions, invisible text, encoded content, or prompt-injection attempts that are risky to pass directly into an LLM. The Markdown API can optionally help detect and sanitize content before conversion, warn your application about suspicious signals, or block high-risk pages entirely.

Sanitize

Helps detect and clean risky content before conversion. Returns safe Markdown for standard RAG workflows, summarizers, and AI pipelines that ingest external pages.

Warn

Returns the original content alongside a risk report — risk score, level, and detected signal names — so your application can log, review, or gate on suspicious pages without automatically discarding them.

Block

Rejects high-risk pages before they reach your AI pipeline, returning a structured error with the full safety analysis so you know exactly why the page was stopped.

AI sanitization is a defense-in-depth layer. It helps detect and reduce risk from common prompt-injection patterns, but it should be combined with safe downstream prompt design, tool permissions, and application-level controls. AI safety sanitization is available on paid plans.

Built for AI Builders, Developers & Content Teams

LLM & RAG Pipelines

FAQ

What is the Webpage to Markdown Tool?

This tool fetches any public webpage and converts its HTML content into clean, LLM-ready Markdown. It uses the OpenGraph.io Markdown API to strip away navigation, ads, and boilerplate, leaving you with just the core content — perfect for feeding into AI pipelines and RAG workflows.

What is Markdown used for?

Markdown is a lightweight markup language used to format plain text. Common uses include:

  • LLM & RAG pipelines – feeding clean web content into AI models and vector stores
  • AI agent toolchains – giving agents real-time web access via LangChain, LlamaIndex, and similar frameworks
  • Documentation – README files, wikis, and technical docs
  • Note-taking – clean, portable notes in tools like Obsidian or Notion

What does "Main Content Only" mean?

When enabled, the tool attempts to isolate the primary article or content body of the page, removing headers, footers, sidebars, ads, and navigation menus. This is ideal for getting the core text of blog posts or documentation pages.

Can I control which HTML tags are included or excluded?

Yes! The advanced options panel lets you specify a comma-separated list of HTML tags to include (e.g. "article,main") or exclude (e.g. "nav,footer,aside"). This gives you fine-grained control over the extracted content.

How many free conversions can I run?

You get a few free conversions tracked by a browser cookie. After that, create a free OpenGraph.io account to unlock API access with 100 monthly credits.

Are there any limitations on which websites can be converted?

The tool works on any publicly accessible URL. Pages behind login walls, paywalls, or JavaScript-heavy SPAs that do not server-side render their content may return limited results.
