Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Write Markdown, see it instantly
A distraction-free editor with a live GitHub-flavoured preview — tables, fenced code blocks, task lists and
blockquotes all render as you type. Switch between Write, Split and Preview, and keep an eye on the word and
character count as you go.
Export a clean .md file, or a self-contained .html page with built-in styling and your document title
— ready to open or publish with no external files. Everything runs in your browser, so your writing never leaves
your device. For a one-off conversion, see Markdown to HTML.
Frequently asked questions
Which Markdown flavour is supported?
GitHub-flavoured Markdown — tables, fenced code blocks, task lists, blockquotes and line breaks all render as they would on GitHub.
What does the HTML export contain?
A single self-contained .html file with clean built-in styling and your document title — ready to open or publish, no external files.
Is my text uploaded?
No — rendering and export run entirely in your browser.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
