What is To Markdown?

To Markdown converts common files and pasted content into Markdown for docs, READMEs, RAG pipelines and LLM context preparation. Files are parsed in the browser, so document contents do not need to leave your device.

How to use

  1. Drop a supported file or paste HTML, JSON, CSV, TSV, RSS, Markdown or plain text.
  2. Choose output options such as links, images, GFM tables, heading cleanup and front matter.
  3. Review the Markdown output, preview it, then copy or download a .md file.

Example

Use this sample to confirm what To Markdown does before pasting your own data.

Input
<article><h1>Guide</h1><p>Hello <a href="https://inbrowser.sh">inbrowser.sh</a>.</p></article>
Output
# Guide

Hello [inbrowser.sh](https://inbrowser.sh).

Files and pasted content are converted locally; PDF output is text-only and can lose layout.

When to use it

Use To Markdown for quick local checks, debugging, documentation prep, and one-off conversions where opening a full IDE or command-line workflow would be slower. For production-critical data, always review the output before committing or shipping it.

Frequently asked questions

Are files uploaded to inbrowser.sh?

No. File conversion runs client-side in your browser. The page may download parser code, but your file contents are not sent to a server.

Which formats are supported?

HTML, DOCX, XLSX/XLS, CSV, TSV, PPTX, JSON, PDF, RSS/XML, RTF, TXT and existing Markdown are supported in this release.

How accurate is PDF to Markdown?

PDF conversion is best-effort text extraction. Tables, columns, images and exact layout can be lossy, so review the output before using it.

Does it convert live web URLs?

Live URL fetching needs a server-side fetcher because browsers enforce CORS. Use saved HTML with this client-side tool; the server URL converter is planned separately.
