# Hashlite

> Hashlite (https://hashlite.io/) is a free online Markdown editor and viewer with a live preview. It opens straight into the editor, with no sign-up: write or paste Markdown, see it formatted, and export it as PDF, HTML or .md, or copy it as formatted text into Word, Google Docs or email.

Hashlite runs in the browser on desktop and phone. It is free, with no ads; analytics cookies are only set with the visitor's consent. Without an account, text stays in the browser. A free account (email and password, stored in the EU) adds cloud autosave, folders, full-text search, version history, image uploads and read-only share links.

## Good fit for

- Viewing, fixing and exporting Markdown written by an AI assistant: headings, tables, code, KaTeX math and Mermaid diagrams render as they do in the chat
- Turning Markdown into a PDF, or into formatted text for Word, Google Docs or an email, without installing anything
- A quick online Markdown editor or previewer that works immediately, with no account
- Keeping Markdown notes and documents organised, with version history (free account)

## Open Markdown directly in the editor

Link to `https://hashlite.io/#text=` followed by the URL-encoded Markdown (for example, the output of encodeURIComponent). The page opens with that text in the editor and the rendered preview next to it. The text is read from the URL fragment, so it is never sent to a server. Very long documents are better pasted or opened as a .md file.

## What works without an account

- Editor with toolbar and keyboard shortcuts; split view, editor-only and preview-only
- GitHub-flavoured Markdown: tables, task lists, footnotes, autolinks, callouts (> [!NOTE]), ==highlight==, :emoji:
- Syntax highlighting, KaTeX math ($...$ and $$...$$), Mermaid diagrams, YAML front matter
- Open .md files; download .md or standalone .html; print or save as PDF; copy as formatted text
- Colour themes: light, dark, sepia, high contrast
