OCR Scanned PDF Documents

Extract and overlay searchable text onto scanned PDFs.

How it Works

  1. Choose the scanned PDF document.
  2. Initiate OCR via chat command ("ocr it") or button.
  3. Gemini Vision processes the page layouts and extracts text layout details.
  4. Interact with, select, or copy text directly from the PDF.

Core Benefits

  • Intelligent automatic scan detection (<50 chars/page)
  • Parallelized page processing for fast execution
  • Invisible searchable text overlays matching layout

Why Choose Client-Side Processing?

Convert scanned PDFs into searchable documents. Our OCR engine runs parallel layouts, matches document fonts, and embeds an invisible selectable text layer on top of pages.

Instead of standard web servers converting, rewriting, or holding files in cache, TellPDF mounts WASM binaries directly in your browser. All memory registers are local and vanish once you reload the page.
