Features

⚡

Live Preview

Every keystroke re-renders instantly in the side-by-side HTML pane.

📊

Full Markdown

Tables with alignment, nested lists, fenced code and quotes all render.

🛡

XSS Safe

Escaped source and scheme-checked links mean pasted markdown cannot attack.

🔒

Local Device Privacy

Everything runs in your browser with plain JavaScript. Drafts never leave your device.

How to Use Markdown Preview

  1. Type or paste markdown into the left editor pane.
  2. Watch the rendered HTML update live in the right preview pane.
  3. Click Copy HTML to grab the markup, or Download .html for a standalone page.
  4. Click Clear to empty the editor and start over.

Markdown in Sixty Seconds

Markdown is plain-text formatting that reads cleanly unrendered and converts to HTML on demand. README files, chat messages, docs sites and static blogs all run on it — one small syntax for headings, emphasis, lists, links and code, learnable in minutes and usable forever.

The everyday core

Hashes make headings, asterisks emphasize (**bold**, *italic*), backticks mark code, dashes build lists and brackets plus parentheses build links. Ninety percent of documents need nothing else. Previewing while writing catches the classic slips — unclosed emphasis, broken link brackets — before publishing.

Tables, code and quotes

Pipes build tables with colon-controlled alignment for comparisons and pricing; triple backticks fence code blocks that keep indentation; greater-than signs quote sources and callouts. Writers pairing prose with data often measure drafts with the Word Counter and time them with the Reading Time Calculator.

Honest limitations

This is a mainstream subset, not every dialect extension: footnotes, definition lists, math blocks and raw embedded HTML are intentionally unsupported (HTML is escaped for safety). Table cells cannot span rows or columns. For very large pastes of tens of megabytes, live rendering on each keystroke can feel slower on older phones.

Privacy and Client-Side Security

Privacy Guarantee: Parsing and preview occur locally inside your browser. Your markdown is never transmitted, stored, or recorded on remote servers.

Many online editors sync every keystroke to a server. TinyToolzz takes a different approach: the parser runs in the page itself with plain JavaScript, dependency-free.

Because nothing is uploaded, there is no waiting, no account, and no copy of your drafts retained anywhere. Your text exists only in the tab's memory and is discarded when you close the page or click Clear.

Frequently Asked Questions

Which markdown features are supported?
Headings, bold, italic, strikethrough, inline code, fenced code blocks, links, images, unordered and ordered lists with nesting, blockquotes, horizontal rules, tables with alignment, and paragraphs. Raw HTML in the source is escaped, never executed.
Is the preview safe from malicious code?
Yes. All source text is HTML-escaped before any markdown processing, and link targets allow only http, https, mailto, anchor and relative URLs. javascript:, data: and similar schemes render as plain text, so pasted markdown cannot run scripts.
How do markdown tables work?
Write a header row of pipe-separated cells, then a delimiter row of dashes, then body rows. Colons set alignment: :--- left-aligns, ---: right-aligns and :---: centers. Every body row needs the same cell count as the header.
Can I copy or download the generated HTML?
Yes. Copy HTML places the rendered markup on your clipboard for pasting into blogs and editors. Download .html saves a complete standalone page with basic styling, ready to open or publish.
Is there a text length limit?
There is no fixed limit. Documents of several megabytes render in memory. Extremely large pastes (tens of megabytes) may respond more slowly because rendering runs on each keystroke.
Is my text uploaded to a server?
No. Parsing and preview happen locally in your browser with JavaScript. Your markdown is never transmitted, stored or logged anywhere. Closing the tab or clicking Clear removes everything immediately.
