Just three simple steps

  1. 1

  2. 2

    Switch between preview and source, then use the table of contents or document search.

  3. 3

    Copy the formatted text or source, and save directly pasted content as an MD file.

Supported formats

Open one MD, MARKDOWN, or TXT file up to 2MB. Text is read as UTF-8.

Read a downloaded MD file without installing an editor

Answers downloaded from ChatGPT, Claude, developer tools, and project README files often use Markdown. Drop the file into Toolit to turn headings, lists, tables, task lists, and code blocks into a readable document without searching for a dedicated editor.

The file is read and rendered only inside your browser. External web images are not requested unless you explicitly enable them, and executable scripts or unsafe HTML in the source are removed before previewing.

Check document structure with the TOC

For a long README, start with the TOC to find setup, usage, and cautions. If a heading is missing, check its # heading syntax in the source. The viewer displays structure; it does not verify AI claims or the safety of code.

Distinguish missing image types

An https:// image can be allowed after checking its source. A relative path such as images/photo.png refers to a separate file that was not supplied with the MD. Enabling external images does not resolve missing relative files.

Preview and source side by side

If a table looks like ordinary text, check its | separators and header divider in the source. For an unclosed code block, check the closing ``` marker. Edit in a text editor and reopen the file; the viewer does not edit source. Use the converter for PDF or Word sharing.

Helpful answers before you start

Which Markdown syntax is supported?

The viewer supports headings, paragraphs, emphasis, links, blockquotes, ordered and unordered lists, tables, task lists, strikethrough, inline code, and code blocks using commonly used GitHub Flavored Markdown syntax.

Why is an image in my document not displayed?

Web-hosted images are blocked by default for privacy and can be enabled from the reading controls. Relative images such as images/photo.png cannot be found when only the MD file is selected, so the viewer shows a notice instead.

Will HTML or scripts inside Markdown run?

No. Scripts, iframes, forms, and unsafe attributes are removed before the preview is shown. Only safe formatting HTML may remain.

What should I do if text looks garbled?

Toolit reads standard UTF-8 text. If an older ANSI or regional encoding looks garbled, save the file as UTF-8 in a text editor and open it again.

Will it look exactly the same as GitHub or an AI service?

The core Markdown syntax is similar, but fonts, colors, code highlighting, and service-specific extensions can differ. Toolit focuses on readable content and document structure.

Can I edit Markdown or export it as PDF?

The viewer does not edit the source, but content opened by pasting can be saved unchanged as an MD file. Use Markdown Converter when you need HTML, PDF, DOCX, or TXT.
