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
Run a 50-page financial report through Pandoc. Three problems are guaranteed:
- Tables flatten. The financial report has 15 tables; the Pandoc output has 0 tables and 15 stretches of pipe-delimited text that don't render as tables in any viewer.
- Multi-column reading order is wrong. The two-column layout reads as scrambled paragraphs alternating between columns.
- Headers and footers leak in. "Confidential" appears 50 times in the output, 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 the same input
Same 50-page financial report through our PDF to Markdown converter. The output:
- Tables come through as GFM tables that render in any viewer and paste cleanly into spreadsheets
- Multi-column reading order is preserved (column 1 top-to-bottom, then column 2 top-to-bottom)
- Headers, footers, and page numbers are detected and stripped
Why the difference: our converter uses layout-aware models specifically tuned for PDF structure recovery, instead of relying on a generic text-extraction primitive. It's a different category of tool — purpose-built for PDF-to-Markdown rather than general-purpose conversion.
Direct head-to-head test
Same 30-page IEEE conference paper. Same scoring rubric (heading detection, table fidelity, equation handling, OCR accuracy, reading order):
| Tool | Headings | Tables | Equations | OCR | Reading order | Total /50 |
|---|---|---|---|---|---|---|
| MDisBetter | 9 | 9 | 9 | 9 | 9 | 45 |
| Pandoc + pdftotext | 3 | 2 | 0 | 0 | 3 | 8 |
Pandoc on PDF gets you about 18% of the quality of a purpose-built tool. The result is text out, not Markdown.
Where Pandoc wins
For non-PDF source formats, Pandoc is the right answer almost every time:
- DOCX to Markdown: Pandoc beats most alternatives
- RST to LaTeX: Pandoc
- Mediawiki to Markdown: Pandoc
- OrgMode to ePub: Pandoc
- AsciiDoc to anything: Pandoc
- Markdown to LaTeX/PDF/DOCX: Pandoc
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:
- 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 — we don't currently ship a CLI or API.) - Step 2 — Markdown to anything else: hand
paper.mdto Pandoc:
pandoc paper.md -o paper.tex
pandoc paper.md -o paper.epub
pandoc paper.md -o paper.docxEach tool does what it does best. PDF parsing is hard, and we specialize in it (in the web UI today). Markdown-to-anything-else is also hard, and Pandoc specializes in it.
What about Pandoc's PDF::XS or other backends?
The Haskell binding to Poppler (pandoc-citeproc ecosystem includes some PDF tooling) gives Pandoc richer PDF access than pdftotext alone. The improvement is real but marginal — you go from "unusable" to "barely usable". Tables and multi-column layouts still break. Equations still get dropped.
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: free tier in the browser (~30 conversions/day), Pro $10/month for higher volume. Web tool only — no CLI, no API, no Python SDK today.
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.
