Plainmark: Convert PDFs into Clean, Usable Markdown

Plainmark is an online PDF-to-Markdown converter designed for people who want structured, portable content without manually rebuilding an entire document.

It supports text-based, scanned, and mixed PDFs. Upload a PDF, and Plainmark extracts its content while preserving useful document structure such as headings, paragraphs, lists, tables, formulas, and images whenever possible. You can review the generated Markdown directly in your browser, copy it for immediate use, or download a ZIP package containing the Markdown file and its related image assets.

Plainmark is useful for developers, researchers, writers, students, and knowledge-management users who need to move content from PDFs into documentation systems, static-site generators, note-taking tools, or AI workflows.

No registration or account is required for the current conversion experience. Each browser session handles one active document at a time, keeping the workflow simple and focused. Uploaded files and generated results are treated as temporary data. They are scheduled for cleanup after delivery, cancellation, failure, timeout, or expiration. Document processing uses an external parsing provider, so users should only upload files they are authorized to process and avoid sensitive documents where third-party processing is unsuitable.

Plainmark focuses on semantic, reusable output rather than merely reproducing the visual appearance of a PDF. The result is Markdown that is easier to read, edit, search, version, and publish.
