How do I convert a PDF to Markdown for free?

Upload your PDF to mdisbetter.com, click Convert, and get clean structured Markdown in seconds. No signup, no installation — it works directly in your browser.

Why is Markdown better than PDF for AI?

Markdown reduces token usage by up to 95% compared to PDF when feeding documents to AI models like ChatGPT or Claude. PDF contains layout metadata, fonts, and binary data that waste tokens. Markdown preserves only the content structure that AI actually needs.

What file types can MDisBetter convert to Markdown?

MDisBetter converts PDF, Word (.docx), plain text, YouTube videos (transcript extraction), audio files (MP3, WAV, M4A, OGG, FLAC, WEBM), and any web page URL to clean Markdown.

Is MDisBetter free to use?

Yes, MDisBetter is completely free. You get 10 conversions per day with no signup required. All tools work directly in your browser.

How do I extract a YouTube transcript as Markdown?

Paste the YouTube video URL into the YouTube to Markdown tool on mdisbetter.com and click Convert. The tool extracts the transcript and structures it as clean, formatted Markdown with headings and timestamps.

Does this preserve citations in academic papers?

Yes — in-text citations like [12] stay attached to their sentence, and the bibliography is emitted as a final ## References section. The numbering matches the original, so cross-references continue to work.

How are equations from academic PDFs handled?

Display equations are converted to LaTeX inside $$...$$ ; inline equations to $...$ . The output renders correctly in any Markdown viewer with MathJax or KaTeX (Obsidian, MkDocs Material, GitHub readme rendering, etc.).

Can I convert arXiv papers directly?

Yes — download the PDF from arXiv (the version-pinned URL works best) and convert. arXiv's LaTeX-derived PDFs are particularly clean, so conversion fidelity is high. For batch academic ingestion, we recommend keeping the arXiv ID in your front matter for traceability.

Does this work on journal PDFs with dense layouts?

Yes for most major publishers (Elsevier, Springer, IEEE, ACM, Nature, Wiley). Layout heuristics handle their column geometries. Edge cases (legal-style margin notes, century-old typesetting) may need manual review of the converted Markdown.

Are figure captions and tables preserved?

Captions are kept attached to a placeholder for the figure (so you can re-insert images by hand if needed) and labelled with their original "Figure 1", "Table 2" identifiers. Tables are converted to GFM where layout permits; complex multi-row headers may need post-edit.

What makes academic PDFs hard

Three problems compound. First, two-column layout: a naïve top-to-bottom extractor reads across columns and produces gibberish. Second, citations: in-text refs like [12] need to stay attached to their sentence, not float to a footnote. Third, math: rendered equations are positioned glyphs, not text — getting LaTeX back requires recognising the equation regions.

Our converter detects multi-column layouts and reads them in correct order, preserves in-text citations as inline references, converts displayed equations to LaTeX ($$...$$) and inline equations to $...$ , and keeps figure captions with their figure numbers so you can find them later.

Reading order on column breaks

The converter analyses block bounding boxes per page, identifies column geometry, and emits text in the order a human reader would follow. Footnotes are collected at the end of the section that referenced them; references appear as a bibliography section at the end. The result reads like the paper, not like the file.
