Learn how to get the most out of Web2MD
Quick Start
Web2MD lets you convert any webpage to clean Markdown in 3 simple steps. Whether you need to feed content to an AI assistant, save it to your note-taking app, or preprocess data for a RAG pipeline, the entire process takes less than 10 seconds.
Install Extension
Add Web2MD from the Chrome Web Store. It's free and takes under 5 seconds to install.
Open Any Webpage
Navigate to any article, blog post, documentation page, or forum thread you want to convert.
Click to Convert
Click the Web2MD icon in your toolbar, or press Control+M (Mac) / Alt+M (Windows). Done!
The converted Markdown is automatically copied to your clipboard, ready to paste into ChatGPT, Claude, Obsidian, Notion, or any Markdown-compatible tool.
Features Overview
Web2MD is purpose-built for the AI era — it goes far beyond a simple HTML to Markdown converter. Its smart extraction algorithm strips away ads, navigation bars, and sidebar clutter to produce optimized Markdown output that reduces token usage by over 60% on average.

Obsidian Export
Prerequisite
This feature communicates with Obsidian via the obsidian:// URI protocol, which requires the Obsidian desktop app to be installed and running on your computer. It does not work on mobile or devices without Obsidian installed.
Convert any webpage and save it directly to your Obsidian vault with one click — a new note is created automatically with the converted content. This is especially useful for building a personal knowledge base, collecting research materials, or archiving important articles. The converted Markdown preserves complete heading hierarchy, links, and formatting, so you can immediately use backlinks and tags in Obsidian.
How to use
- Open the extension → switch to the Settings tab
- In the Obsidian section, toggle on "Enable Obsidian Export"
- (Optional) Enter your vault name — leave empty to use the Obsidian default vault
- Switch to the Convert tab and convert the current page
- After conversion, click "Save to Obsidian" — Obsidian will open and create a new note automatically
Note: Individual notes are limited to 2MB. If the content exceeds this limit, it will be automatically truncated with a note at the end.
Send to AI
Send the converted Markdown content directly to Claude, ChatGPT, Gemini, Perplexity, Grok, or DeepSeek with one click. Web2MD's smart extraction ensures the content sent to AI is clean and structured, avoiding wasted tokens on ads and navigation clutter. Pro users save approximately 2 million tokens per month on average, equivalent to about $17 in API costs.
- Choose your preferred AI platform in Settings
- After converting a page, click the AI platform button in the popup
- Content is automatically pasted into the AI chat — enable "Auto Send" to skip the manual paste step
Tip: Works even better with Prompt Templates. For example, select the "Summarize" template before sending to Claude to automatically prepend a summary instruction.
Batch Convert
Convert multiple URLs or currently open browser tabs at the same time. Batch conversion is ideal for scenarios where you need to process many webpages at once, such as competitive research, literature review, or content archiving. All results can be merged into a single Markdown download, or copied individually.
- Switch to the Batch tab in the extension
- Paste multiple URLs (one per line), or click "Add open tabs" to automatically import all currently open pages in your browser
- Click "Start" — progress is shown in real time, with each URL's status tracked independently
- Once done, copy or download all results at once, or merge all content and send it to AI in one request
Prompt Templates
Prepend custom instructions to content before sending to AI. This is especially useful in an AI workflow — you can preset different prompts for different tasks and complete the entire "convert webpage + add instruction + send to AI" flow with one click. Four built-in templates are included:
- •Summarize — generate a concise summary to quickly grasp key points
- •Translate — translate to a target language, supporting any language
- •Key Points — extract main points, great for meeting notes and research reports
- •ELI5 — explain complex content in simple terms, ideal for learning new fields
You can also create, edit, and delete custom templates in Settings → Prompt Templates. For example, you might create a "Code Review" template that instructs AI to analyze code examples in converted technical documentation.
Supported Platforms
Web2MD can convert virtually any public webpage to Markdown. In addition to our general-purpose HTML extraction algorithm, we have built 14 dedicated extractors for popular websites in the following categories, ensuring optimal conversion quality. No matter what source you want to convert webpage to markdown from, Web2MD has you covered.
News & Media
The New York Times, BBC, Reuters, The Guardian, Bloomberg, TechCrunch, The Verge, Ars Technica
Articles, editorials, and long-form journalism. Paywalled content is accessible if you are logged in via the Chrome extension.
Technical Documentation
MDN Web Docs, React Docs, Next.js Docs, Python Docs, Stack Overflow, GitHub READMEs and Issues
Code blocks are preserved with correct language tags and indentation. Tables and API references maintain their structure.
Blogging Platforms
Medium, Substack, WordPress, Ghost, Hashnode, dev.to, Blogger
Dedicated extractors for Medium and Substack remove membership prompts, claps UI, and email signup forms automatically.
Social Media & Forums
Reddit threads, Twitter/X threads, Hacker News, Discourse forums, Quora
Reddit extractor captures the original post and top comments with proper threading. Twitter/X threads are concatenated in order.
Academic & Research
arXiv (HTML versions), PubMed, Google Scholar, ResearchGate, Wikipedia, Britannica
Citations, footnotes, and mathematical notation are preserved where possible. Wikipedia infoboxes are converted to Markdown tables.
Video & Multimedia
YouTube (descriptions, transcripts), Vimeo, podcast show notes
YouTube extractor captures video metadata, description, and transcript (if available) in a structured Markdown format.
The above lists only representative websites. Web2MD's general extraction algorithm supports any standard HTML webpage. If you find that conversion quality is poor for a specific site, let us know at support@web2md.org and we will evaluate whether a dedicated extractor is needed.
Keyboard Shortcuts
Convert the current page to Markdown and copy to clipboard without opening the popup. For power users, the keyboard shortcut dramatically improves efficiency — just press the shortcut and the web to markdown conversion happens in the background, with a notification letting you know the content is ready.
Mac
Control + MWindows / Linux
Alt + MContext Menu
In addition to keyboard shortcuts, you can right-click on any webpage or selected text and choose "Copy as Markdown" from the context menu. If you have selected a portion of text, only the selected content will be converted — this is very useful when you only need a specific paragraph or code block from an article.
Use Cases
Web2MD is suitable for any scenario that requires converting webpage content into structured text. Here are the most common ways our users put it to work:
RAG Pipeline Preprocessing
Building a Retrieval-Augmented Generation system? Web2MD produces clean, structured Markdown that is ideal for chunking and embedding. By stripping away HTML noise, ads, and navigation elements, Web2MD reduces document size by 60-80%, which means faster indexing, lower storage costs, and more relevant retrieval results in your RAG pipeline.
Obsidian & Notion Note-Taking
Clip web articles directly into your Obsidian vault or paste clean Markdown into Notion pages. Web2MD preserves headings, links, images, code blocks, and tables so your notes look exactly like the original content — without the clutter. Build a searchable personal knowledge base from the web without manual formatting.
Feeding AI Assistants
Send cleaned web content to ChatGPT, Claude, Gemini, or other AI assistants for summarization, translation, analysis, or Q&A. Web2MD's token savings mean you can feed longer articles to AI without hitting context window limits. The one-click Send to AI feature makes the entire flow seamless.
Content Archiving
Archive important web content in a future-proof format. Unlike bookmarks that can break when pages are taken down, Markdown files are portable, searchable, and will remain readable decades from now. Use batch conversion to archive entire collections of articles at once.
Developer Documentation
Convert technical documentation, API references, and Stack Overflow answers to Markdown for offline reading, team sharing, or feeding to coding assistants like GitHub Copilot and Claude. Code blocks are preserved with correct syntax highlighting tags, making the output immediately useful.

API & Integration
Web2MD currently offers two primary ways to convert webpage content to Markdown:
Chrome Browser Extension
Our core product. Convert HTML to Markdown directly in your browser — all processing happens locally with no data uploaded to servers. Supports one-click conversion, Send to AI, Obsidian export, batch processing, and all other features. Ideal for daily browsing and content collection.
Web Version
Convert by entering a URL on our website — no extension installation required. Ideal for one-off use, mobile users, or environments where extensions cannot be installed. Sign in to enjoy the same conversion quota as the extension.
API Access (Pro Feature)
Pro users can integrate Web2MD's conversion capabilities into their own applications and workflows via API. The API delivers the same smart extraction and Markdown output quality as the extension, making it suitable for automated RAG pipelines, content monitoring systems, and custom AI workflows. Check the pricing page for Pro plan details.
Frequently Asked Questions
What types of web pages can Web2MD convert?
As a versatile markdown converter, Web2MD can handle virtually any publicly accessible webpage, including news articles, blog posts, technical documentation, forum threads, product pages, and academic papers. We have 14 dedicated extractors optimized for popular platforms like Medium, Substack, Reddit, GitHub, YouTube, and WordPress. For standard websites, our general-purpose extraction algorithm handles most HTML structures with over 97% format accuracy. Pages behind login walls or those that require JavaScript interaction may have limitations — see the Troubleshooting section below for details.
Is my data secure when using Web2MD?
Absolutely. All conversions performed through the Chrome extension happen entirely on your local device — we never upload or store any of your web content on our servers. The conversion engine runs in your browser's sandboxed environment, which means your data never leaves your computer. For the web version, URLs are fetched server-side for conversion, but the content is processed in memory and not persisted. We use SSL encryption for all communications and comply with standard data protection practices. You can review our full privacy policy for more details.
How accurate is the token counting feature?
Web2MD's token counting uses algorithms similar to the tokenizers employed by GPT-4 and Claude, achieving accuracy above 95% across all major models. Due to slight differences between tokenizers (for example, GPT-4 uses cl100k_base while Claude uses its own tokenizer), we recommend leaving a 5-10% margin when planning your prompts. The token count is displayed instantly after each conversion, helping you estimate API costs and ensure your content fits within the model's context window. Pro users save approximately 2 million tokens per month through our optimized extraction.
What is the difference between Free and Pro plans?
The Free plan includes 3 conversions per day with smart content extraction and basic Markdown output. The Pro plan ($9/month or $49.99/year) unlocks unlimited conversions, conversion history, precise token counting, smart content splitting, AI auto-tags and summaries, Markdown file downloads, automatic platform collections, and API access. Pro also includes priority support and early access to new features. If you convert webpages regularly for AI workflows or research, Pro typically pays for itself through token savings alone — Pro users save about $17/month in API costs on average.
See the pricing page for a full feature comparison and plan details.
Troubleshooting
Most webpages convert smoothly, but certain edge cases may require extra attention. Here are common issues and their solutions:
Some pages produce empty or incomplete results
This typically happens with Single Page Applications (SPAs) that rely on client-side JavaScript to render content, such as some React/Vue/Angular apps. Web2MD reads the current DOM state of the page, and if content has not fully loaded, it may not capture everything.
Solution: Wait for the page to fully load before clicking convert. If the page uses infinite scroll, scroll down to load the content you need first, then perform the conversion.
Content behind paywalls or login walls
If webpage content requires login or payment to view, Web2MD's Chrome extension can only convert content that is actually visible in your browser. If you are already logged in and can see the full article, the extension will convert it normally. However, the Web version fetches pages by URL and cannot use your login credentials, so it can only capture the publicly visible portion.
Solution: For paywalled content, use the Chrome extension (not the Web version). Make sure you are logged in and can see the full content in your browser before converting.
Lost formatting or layout issues
A small number of websites use non-standard HTML structures or rely on CSS to convey content hierarchy (e.g., using divs instead of semantic heading tags), which can result in some formatting being lost in the converted Markdown. Additionally, pages that embed text within images (such as some marketing pages or PDF screenshots) cannot be extracted as text.
Solution: If you encounter conversion issues with a specific website, please report it via support@web2md.org and we will evaluate whether a dedicated extractor is needed.
Extension icon is greyed out or unavailable
Chrome restricts extensions from running on certain special pages, including chrome:// internal pages, Chrome Web Store pages, and the PDF viewer. On these pages, the Web2MD extension icon will appear greyed out and cannot be clicked.
Solution: This is a Chrome browser security restriction, not a Web2MD issue. Navigate to a regular webpage to use the extension. For PDF files, consider uploading them to an online PDF viewer first, then converting.
