How to Merge Markdown (3 Steps)

  1. Choose your Markdown files. Select two or more .md files in reading order.
  2. Merge. The documents are joined with a blank line so headings and lists stay valid.
  3. Download the merged document. Open it in your Markdown editor or static site generator.

In short: this page is best for a quick, small file. For large files or batch jobs, use the TextMerger desktop app — it also ships a command line for scripts and scheduled runs.

What to Know About Markdown

  • Heading levels are copied as-is, so check them after merging chapters.
  • A blank line is inserted between files to keep blocks separated.
  • Code fences, tables and links are preserved.
  • No table of contents is generated automatically.

Frequently Asked Questions

Will the merged headings be renumbered?

No, heading levels are kept exactly. Adjust them in your editor if two files both start with H1.

Can I add a table of contents?

Not automatically. Merge the files, then use your editor or static site generator to build a TOC.

Is my content uploaded?

No, everything is merged locally.
