Unlimited OCR

Long PDF & Image to Markdown

Visit

Unlimited OCR is an online tool for converting PDFs and document images into structured Markdown. Upload a scanned PDF, research paper, screenshot, or photo and

review the extracted content beside the original file.

The tool aims to preserve headings, paragraphs, lists, tables, formulas, images, and reading order instead of returning a single block of plain text. You can preview

the result, copy the Markdown, or download a ZIP containing the Markdown and available image assets.

Unlimited OCR supports common PDF and image formats. PDFs can contain up to 50 pages. Files are processed in the cloud using Baidu Unlimited-OCR.
