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.
Scan long responses by heading, use the generated table of contents, and search for the section you need.
Reading the document does not request images from another website unless you choose to allow them.
Switch to source whenever you need to compare the rendered result with the original Markdown syntax.
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.
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.
No. Scripts, iframes, forms, and unsafe attributes are removed before the preview is shown. Only safe formatting HTML may remain.
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.
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.
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.
