Privacy-first by design
The converter works from the browser tab and does not need a backend upload endpoint.

Convert files to Markdown without uploading them
Markdown Safe converts DOCX, PDF, TXT, HTML, and RTF files directly in your browser. Choose a file below, review the Markdown, then copy or download it.
Drop a file to convert
DOCX, PDF, TXT, HTML, and RTF are converted locally in this browser.
Your file is processed locally in your browser and is never uploaded.
Choose a file to begin.
Supported formats
DOCX, PDF, TXT, HTML, and RTF. Recommended maximum size: 25 MB.
Built for Markdown workflows
Use the output in documentation, notes, GitHub, static sites, and editor-based publishing.
Clear format limits
The app explains when PDF layouts, scanned files, or RTF formatting may need manual review.
Format notes
Each format has different strengths and limits. These notes explain what to expect.
DOCX to Markdown
Convert Word documents while preserving headings, emphasis, lists, links, and many tables.
PDF to Markdown
Extract readable PDF text with page markers. Best for text PDFs, not scanned image-only files.
HTML to Markdown
Turn semantic HTML into Markdown while removing scripts, styles, and iframes.
TXT to Markdown
Normalize plain text spacing and line endings for a clean .md file.
Private file converter
Use a no-upload document converter built around browser-based processing.
Supported formats
Start with one file. The converter supports common document exports.
DOCX
Headings, links, lists, tables where possible
Readable text with page separators
TXT
Clean text and paragraph spacing
HTML
Semantic HTML to Markdown
RTF
Readable text extraction
How it works
A simple local pipeline, no upload step hidden in the middle.
1
Select
Choose a DOCX, PDF, TXT, HTML, or RTF file from your device.
2
Read locally
The browser reads the file in memory. No upload request is made.
3
Convert
Client-side parsers extract content and normalize it into Markdown.
4
Preview
Review raw Markdown or switch to a rendered preview.
5
Copy
Copy the Markdown directly to your clipboard.
6
Download
Save a .md file and clear the page when finished.
Questions people ask first
Are my files uploaded?+
No. Files are read by your browser and converted locally. Markdown Safe does not send document files to a server for conversion.
Do you store my files?+
No. There is no document database, account system, or server-side file storage in the converter flow.
Can you read my documents?+
The app code running in your browser processes the file so it can produce Markdown. The document is not transmitted to Markdown Safe servers.
Does this work offline?+
After the app and conversion libraries have loaded, conversion logic runs locally. A dedicated offline app could make this even stronger in the future.
Why do some PDFs convert poorly?+
PDFs are layout containers, not structured documents. Scanned, image-based, encrypted, or multi-column PDFs may extract poorly.
Is DOCX formatting preserved?+
Common document structure such as headings, paragraphs, emphasis, links, lists, and many tables is preserved where the DOCX contains that structure.
Can I convert multiple files?+
The current converter handles one file at a time. The app is structured so batch conversion can be added later.
Is this safe for sensitive documents?+
The no-upload architecture is designed for sensitive documents, but you should still use your own security requirements and verify the app behavior in browser developer tools.
Do you use AI to read my files?+
No. Conversion uses deterministic client-side parsing libraries and local browser APIs, not AI document analysis.
Can I self-host this?+
Yes. The app is built as a static-friendly Next.js application with no required backend for conversion.
