Uploaded files and conversion results
When you choose conversion, the browser sends the selected file to a same-origin server endpoint. That endpoint validates the request and passes the file to a private MarkItDown conversion service. The file is processed for the duration of the request and temporary working data is removed immediately afterward.
The service does not intentionally retain uploaded files or converted Markdown on the server after the request completes. Responses use no-store caching directives. The public conversion endpoint does not fetch remote URLs or enable third-party converter plugins.
Documents stored in your browser
Editor drafts and recent-document metadata are stored locally in the browser so work can survive navigation and refresh. Opaque document IDs may appear in an editor route, but filenames and document contents are not placed in the URL.
Local browser data remains on that browser profile until you delete an individual document, clear all recent documents, clear site data, or use browser controls that remove storage. Other devices do not automatically receive those drafts.
Operational and security data
The conversion boundary may process basic request metadata needed for security, availability, rate limiting, and error handling. Application logging is designed to omit original filenames, uploaded contents, and converted Markdown.
No system can promise absolute security. Limit uploads to material you are authorized to process, remove unnecessary secrets and personal data, and download important work to a location you control.
Open-source conversion and external links
Conversion uses the open-source Microsoft MarkItDown Python package in a private service. This website is independently operated; Microsoft does not own, sponsor, or operate it. The default conversion path does not send documents to Microsoft or a cloud OCR service.
Public pages may link to third-party websites such as the MarkItDown source repository. Their privacy practices apply after you follow those links.
Your controls
You can write Markdown without uploading a source file, delete local documents individually, clear all recent documents, and clear this site's browser storage. You can also cancel an in-progress upload where the browser and request state permit it.
If the deployment provides a support or privacy contact, use that published channel for requests about server-side operational data. Local drafts can only be managed from the browser profile where they are stored.
