Frequently asked questions
When should I pick MarkItDown over MDisBetter?
When you need a single library that handles many formats (Office + PDF + images + audio transcripts) inside an existing Python pipeline, with the trade-off of weaker PDF output. MarkItDown is genuinely good at format breadth; PDF is one of its weaker formats.
Is MarkItDown free?
Yes — open-source, Apache 2.0 licence. You bring the compute. MDisBetter has a free tier (50 credits/month) and paid tiers ($9–139/mo) for higher volume. Both have a "free for personal" path.
How does table quality compare?
MDisBetter detects tables via line-detection and emits GFM-formatted tables that round-trip into spreadsheets. MarkItDown often flattens table content into prose, especially for borderless or complex tables. For data-heavy PDFs, the gap is large.
Does MarkItDown handle equations?
Not as LaTeX — equations come through as best-effort text or are skipped. For technical and academic content, this is a meaningful gap. MDisBetter detects equation regions and emits LaTeX in
$...$ blocks.Can I use MarkItDown alongside MDisBetter?
Yes — common pattern: MarkItDown for the long tail of Office formats in your ingestion pipeline, MDisBetter for PDFs specifically. Same downstream consumer (LLM, vector DB) reads Markdown either way.
