Frequently Asked Questions

Markdown Previewer FAQ

A Markdown previewer is an online tool that converts plain-text Markdown formatting into rendered visual HTML in real time. As you write headings, lists, tables, or code blocks in the editor pane, the parser translates syntax markers into styled elements on the preview pane immediately without needing page refreshes.
Yes. You can click the Upload button or drag and drop any .md, .markdown, or .txt file straight into the editor. The tool reads your file locally using the browser FileReader API without uploading any data to external servers.
Yes. It supports standard GitHub Flavored Markdown extensions including multi-column tables, task lists with checkboxes, strikethrough text, blockquotes, and fenced code blocks.
Completely. All parsing, rendering, and file reading happen entirely inside your client browser session using local JavaScript. No text, uploaded files, or document contents are ever transmitted across a network or stored on our servers.
Clicking the Fullscreen button expands the workspace across your entire monitor while keeping the raw editor and live preview side by side. This gives you a wide, distraction-free environment for drafting long documentation. Press Escape or click the exit button to return.
Yes. You can switch the preview view mode to inspect the raw HTML code, copy the generated HTML markup directly to your clipboard, or download it as a standalone styled .html file ready for the web.
Create tables by separating column headers with pipe symbols (|) and placing a delimiter line of hyphens below them (such as | Header 1 | Header 2 | followed by | --- | --- |). Any rows added underneath will render as structured table cells.
Yes. Once the page finishes loading in your web browser, all parsing and file preview features operate locally in your active session, allowing you to edit and preview Markdown even if your internet connection disconnects.
Standard CommonMark provides fundamental styling like headings, lists, links, and bold text. GitHub Flavored Markdown builds on this standard by adding tables, autolinks, strikethrough formatting, task checklists, and language-tagged code fences commonly used in developer documentation.
When synchronized scrolling is enabled, navigating through the raw Markdown editor automatically scrolls the preview pane to the matching relative position, keeping your cursor and rendered text aligned.

All Markdown processing and file reading run strictly in your web browser. No text, documents, or personal data are ever uploaded or saved to our servers.
