How In-Browser Searchable PDF OCR Works

When a paper document is scanned to PDF, it consists of raw raster images where text cannot be selected, copied, or searched (Ctrl+F). This tool renders each page at high resolution using PDF.js, detects word coordinates with Tesseract.js WebAssembly, and synthesizes a dual-layer PDF/A using PDF-lib with exact matching invisible text glyphs directly on top of the original imagery.

Make Scanned Documents Searchable with Local OCR

Transform non-searchable PDF scans into fully searchable and selectable PDF files. Generates an invisible matching text layer overlaid onto the original page imagery with exact coordinate positioning.
