Know the limits

Local does not mean unlimited.

Browser processing avoids an upload workflow, but available memory, PDF structure, digital signatures, and the settings you select still matter.

  • PDF stores positioned drawing instructions rather than reliable document structure.
  • Tables, columns, footnotes, formulas, and reading order can require manual correction.
  • Scanned pages need OCR, which this tool does not perform.

Clear answers

PDF to Markdown questions.

Will the Markdown match the original layout?

Not exactly. The tool prioritizes readable text and uses heuristics because PDFs do not consistently encode semantic structure.

Can it read scanned pages?

No. Image-only scans require OCR and will produce little or no text here.

Is AI used?

No. Text extraction and formatting heuristics run deterministically in the browser.
