Frequently Asked Questions
What is the best free PDF to Markdown converter?
MDisBetter offers free online conversion in your browser with 50 free credits per month and AI-powered formatting. For local processing without limits, Marker is the best open-source option with GPU acceleration and batch capabilities.
Can I convert PDFs to Markdown without installing software?
Yes, absolutely. MDisBetter allows you to convert PDFs directly in your browser without any installation, just upload and download. You only need a free account, and the free tier comes with a monthly credit allowance.
Which converter handles tables best?
Marker and MDisBetter both preserve table structure and formatting better than most alternatives. Adobe Acrobat also handles complex tables well but requires a paid subscription. For simple tables, Pandoc works adequately.
Is there a PDF to Markdown API available?
LlamaParse provides a production-ready API-based solution ideal for scaling AI pipelines. MDisBetter has no API: it is a web tool you use in your browser. Its open-source MCP server lets an MCP client such as Claude or Cursor convert one local file at a time, but it is not an API you can build into your own application.
