MDisBetter vs Pandoc for PDF Conversion

Pandoc is the swiss-army knife of document conversion: 100+ input formats, 100+ output formats, configurable through the most flexible CLI in the field, free and open source, scriptable. PDF input is its weakest leg, and not because Pandoc is bad, but because PDF doesn't fit Pandoc's document model. MDisBetter is a different shape entirely: a web tool, no install, purpose-built for PDF-to-Markdown. They solve different parts of the same problem. Here's the honest comparison.

How Pandoc handles PDF input

Pandoc has no native PDF reader. PDF input requires an external helper: typically pdftotext from poppler-utils, sometimes a Pandoc-PDF Haskell binding for richer access. Whatever helper you use, the workflow is: external tool extracts text from the PDF, Pandoc reads that text, Pandoc emits Markdown.

The key consequence: Pandoc's quality on PDF input is bounded by pdftotext's quality. pdftotext gives you reading-order text: usable for trivial PDFs, broken on anything with multi-column layout, tables, or complex structure. Pandoc then writes that broken text out as broken Markdown.

Where Pandoc fails on PDF

Put a long financial report with tables and a two-column layout through Pandoc + pdftotext. Three problems are typical:

  1. Tables flatten. The tables come out as stretches of text that don't render as tables in any viewer.
  2. Multi-column reading order is wrong. The two-column layout reads as scrambled paragraphs alternating between columns.
  3. Headers and footers leak in. A running header such as "Confidential" comes back once per page, and page numbers appear as orphan paragraphs between sections.

None of this is Pandoc's fault: it's working with what pdftotext hands it. But the result is unusable for any practical purpose: not readable as a document, not feedable to an LLM, not searchable with reasonable accuracy.

How MDisBetter handles PDF input

Our PDF to Markdown converter is built for this one job instead of relying on a generic text-extraction primitive: heading levels are preserved and tables are rebuilt as Markdown tables that render in any viewer. It's a different category of tool, purpose-built for PDF-to-Markdown rather than general-purpose conversion.

How to compare them on your own PDF

Take one of your own documents, ideally one with tables and columns, and convert it both ways. Then check the two Markdown files side by side against the source: are the headings real ## headings, do the tables render as tables, does multi-column text read in the right order, and did any running headers or page numbers leak into the text? How to benchmark PDF to Markdown converters gives a full scoring grid if you want to go further.

Where Pandoc wins

For non-PDF source formats, Pandoc is the right answer almost every time:

If your conversion involves any format other than PDF source, install Pandoc first and reach for it before anything else. We're not trying to compete with Pandoc on its strong suit.

The right pattern: chain them

The cleanest workflow uses both tools, just at different stages:

  1. Step 1; PDF to Markdown: drag your PDF into the MDisBetter web tool, click Convert, download paper.md. (For unattended automation, use OSS like Marker or Docling locally: MDisBetter is a web tool only.)
  2. Step 2; Markdown to anything else: hand paper.md to Pandoc:
pandoc paper.md -o paper.tex
pandoc paper.md -o paper.epub
pandoc paper.md -o paper.docx

Each tool does what it does best. PDF parsing is hard, and it is what our web tool is built for. Markdown-to-anything-else is also hard, and Pandoc specializes in it.

What about other PDF backends?

Swapping the helper that extracts text in front of Pandoc doesn't remove the core problem: whatever does the extraction, tables, multi-column layouts and equations still have to be reconstructed by something, and Pandoc's writers only receive what the helper hands them.

The fundamental issue is that PDF doesn't expose the structure Pandoc's writers need. No backend changes that.

Cost

Pandoc: free open source, CLI-first, scriptable. MDisBetter: a free account in the browser, where each conversion uses credits, with paid plans for more volume. Web tool only.

For pure non-PDF Pandoc workflows, no money changes hands either way. For PDF input as part of a Pandoc workflow, the realistic options are: drop the PDF through our web tool (one-off) or run an OSS extractor like Marker locally (automation), then hand the Markdown to Pandoc.

Summary

Pandoc remains the right tool for almost every format conversion that doesn't involve PDF input. For PDF source, it's the wrong tool: not because Pandoc is bad, but because the format mismatch breaks every PDF-specific extraction step. Use both: MDisBetter to convert PDF to Markdown, Pandoc to convert Markdown to anything else.

Frequently asked questions

Can Pandoc convert Markdown back to PDF?
Yes, and it does this very well. Pandoc + LaTeX produces publication-quality PDFs from Markdown. The conversion direction matters: Markdown to PDF works great in Pandoc; PDF to Markdown does not.
Is Pandoc free?
Yes, GPL open source. It's a great piece of software, just not for PDF input. We highly recommend it for everything else.
Should I install both Pandoc and use MDisBetter?
For most teams, yes. Pandoc handles all your non-PDF conversions; MDisBetter handles the PDF-to-Markdown step. They're complementary, not competitive.
