Unlimited OCR Online – PDF & Image to Markdown
Unlimited OCR is an online tool that converts scanned PDFs, research papers, screenshots, and document images into structured Markdown. It extracts text while retaining headings, lists, tables, formulas, images, and reading order where possible. Users can compare the source with a rendered preview, copy the Markdown, or download a ZIP with available image assets. It supports common PDF and image formats and processes PDFs up to 50 pages using Baidu Unlimited-OCR.
