Edit Markdown and README files online with live preview, outline, images, local drafts, and export to MD, HTML, or ZIP.

Browser Markdown editor with source text, live preview, outline, and export controls

Why use a Markdown editor?

Markdown is useful because it keeps writing simple. You can write headings, lists, links, tables, quotes, task lists, and code blocks without fighting a heavy document layout.

The Markdown Editor gives you a browser workspace with source text, live preview, outline, search and replace, undo and redo, line numbers, foldable sections, templates, and image handling.

It is a good fit for README files, notes, release drafts, documentation pages, article outlines, and simple knowledge-base content.

Quick workflow

Open Markdown Editor, start from a blank page or open a .md, .markdown, .txt, .html, or supported ZIP package. Write on one side, watch the preview, use the outline to move around headings, then export the result.

If you only need to convert Markdown to HTML or HTML to Markdown, use Markdown Converter. Use the editor when you need to write and review the document.

Working with images

Markdown files usually store image paths, not the images themselves. If you move only the .md file, local images may disappear because the paths no longer point to real files.

The editor supports adding images by button, library, paste, or drag and drop. For moving a document together with its images, export the document and images as a ZIP. HTML export can embed local images inside the output.

Online images are different: they stay as external links unless you choose to load them. That connection goes to the site hosting the image, so use it deliberately.

Drafts and privacy

The editor keeps a local browser draft, including local images, so you can recover recent work on the same device and browser. Still, important writing should be downloaded because browser storage can be cleared.

The document and images are not uploaded to the IGY Apps server for editing. The practical habit is simple: write, preview, export, and keep your own copy.

Before publishing

Before you publish or share Markdown, check:

  • Heading levels are in order.
  • Links open the right pages.
  • Images are included or use valid paths.
  • Tables are readable on small screens.
  • Code blocks have the right language.
  • The document length matches the audience.

Use Word Counter when you need to keep a README introduction, article, or note within a specific length.

A useful README structure

A clear README normally starts with the project name and one-sentence purpose, followed by installation, usage, configuration, and examples. Add troubleshooting and license sections only when they help the reader. Use one H1 for the document title and nest H2 and H3 headings in order so the outline remains easy to scan.

The live preview is useful for catching broken lists, tables, code fences, and image paths before publishing to GitHub or another documentation site. Export the .md file for source control, HTML for a standalone preview, or ZIP when local images must travel with the document.

Frequently asked questions

Can I edit an existing MD or README file online?

Yes. Open a .md, .markdown, or supported text file, edit it with live preview, and export the updated Markdown.

Are drafts saved automatically?

A local draft is stored in the same browser, but it can disappear if browser data is cleared. Download important work regularly.

Can I export Markdown with images?

Yes. ZIP export packages the document with local images, while HTML export can embed those images into one file.
