How it works
Preview Markdown in three steps
Use the live Markdown editor online without sending the document to Nanomite. The source and rendered view stay together in one focused workspace.
- 01 Write, paste, or open Markdown.
Start with the editable sample, paste plain text, or open one local Markdown or text file up to 2 MB.
- 02 Check the live Markdown preview.
For documents under 200,000 characters, headings, lists, tables, task lists, code, footnotes, and math update as you type.
- 03 Review technical content.
Read highlighted code, KaTeX formulas, and locally rendered Mermaid diagrams beside the original source.
01 / Markdown
Read GitHub Flavored Markdown
Preview standard Markdown plus strikethrough, autolinks, tables, task lists, footnotes, and stable heading links. Raw HTML is displayed as text instead of being executed.
02 / Technical
Render math, code, and Mermaid
KaTeX formats inline and display math, common programming languages receive syntax highlighting, and Mermaid fences become diagrams after the preview loads.
03 / Privacy
Keep Markdown processing local
Parsing and rendering happen in your browser. Nanomite does not upload, store, or put the Markdown in the page URL, and no account is required.
External resources
Know when a preview can make a request
An image with an http:// or https:// address is loaded from its original
host, so that host receives a normal browser request. Image requests omit the referring page,
but still reveal information such as the browser's IP address.
Relative, root-relative, and protocol-relative image paths are shown as inert text and are
not requested from Nanomite or another server. Embed a supported image as a data URL or
use an explicit http:// or https:// address when it needs to appear.
