Turn screenshots and scans into searchable text

Hundreds of images, screenshots and scanned contracts converted into copyable, searchable text that you can find again by keyword.

What you end up with

  • Text you can copy instead of retyping
  • Tables and paragraphs with layout preserved
  • An archive searchable by keyword

The sequence

  1. 1. Identify what kind of document you have

    Plain scans and complex layouts (multi-column papers, tabular reports) need different tools. The wrong one still returns text, just in the wrong order — and redoing it costs more than choosing correctly up front.

    PaddleOCR
    PaddleOCROpen source★ 91.5KUse AI to recognize text in images and PDFs, turning documents into editable, searchable structured data, supporting over 100 languages.
    Umi-OCR
    Umi-OCROpen source★ 48.1KA free offline OCR text recognition tool. Extract text from screenshots or imported images, with support for PDF recognition and QR codes.

  2. 2. For complex layouts, parse the document rather than OCR it

    Documents with tables, columns or formulas should go through a layout parser that emits Markdown or JSON, preserving structure. This decides whether downstream text is usable at all.

    MinerU
    MinerUOpen source★ 82.2KAccurately convert PDF and Office documents to Markdown and JSON, suitable for direct use with AI models.
    docling
    doclingOpen source★ 69.3Kdocling is a document parsing tool that converts PDF, Word, and other documents into AI-friendly Markdown or JSON formats, making it easy to feed to large models.
    Stirling-PDF
    Stirling-PDFOpen source★ 94.7KA feature-packed PDF toolbox that can edit, convert, sign, OCR, free and open-source, self-hostable.

  3. 3. Archive it so it's findable later

    Converting without archiving means you still can't find it in three months. Store the extracted text alongside the original image with full-text search.

    paperless-ngx
    paperless-ngxOpen source★ 47.0KAn open-source system that scans, archives, and searches paper documents, keeping document management organized.
