OCR PDF editor: make any PDF searchable and editable

An OCR PDF editor does two jobs at once: it reads the text out of image-only pages, and it lets you work with that text right away. blupdf recognizes each scanned page with AI OCR, keeps the layout - paragraphs, headings, tables - as editable blocks, and exports a PDF with a proper text layer so the file is searchable everywhere.

How it works

  1. Step 1

    Upload an image-only PDF

    Scans, faxes, 'printed to PDF' images and phone photos are all detected as image pages on upload.

  2. Step 2

    OCR with layout detection

    blupdf recognizes the text and its structure: reading order, block boundaries, sizes and colors. 80 credits per page, charged once.

  3. Step 3

    Review and correct

    Recognized text is editable immediately. Search for suspicious characters, click a block and fix it.

  4. Step 4

    Export with a text layer

    The exported PDF keeps the page image and adds invisible, selectable text behind it - plus rendered text wherever you edited.

Why blupdf

  • Searchable in any viewer

    The text layer is standard PDF text, so Preview, Acrobat, browsers and document systems can search and index it.

  • Structure, not just characters

    Layout detection keeps paragraphs and table cells as separate blocks, which is what makes later editing clean.

  • Edit in the same step

    There is no separate OCR product to run first; recognition happens on upload and editing starts right away.

  • Privacy by default

    Pages are sent to the OCR model only to be recognized, are not used to train models, and are deleted with the document.
