Invisible Selectable Text Layer • Searchable .PDF & .TXT ExportWhy Use Utilvo's Searchable PDF Creator?
Designed for legal archives, academic research libraries, and paperless office workflows, Utilvo's Searchable PDF Creator converts flat scanned PDF documents and photographed pages into fully searchable, mouse-selectable PDF files.

Frequently Asked Questions
How does a Searchable PDF Creator make a flat scanned PDF selectable?
A flat scanned PDF only contains static page images with no underlying character data. Utilvo's Searchable PDF Creator renders each page, runs optical character recognition (OCR) to detect word coordinates, and embeds a transparent text layer mapped to those exact positions inside a downloadable PDF.
Will making my scanned PDF searchable change how the document looks?
No. The original scanned page image remains completely unchanged on screen, preserving official letterheads, stamps, tables, and wet signatures, while the newly added OCR text layer stays invisible until you highlight or search it.
Can I use Ctrl+F or Command+F to search inside the exported PDF?
Yes. Once you download the searchable PDF, you can open it in Adobe Acrobat Reader, Apple Preview, Chrome, Edge, or Firefox and press Ctrl+F (or Cmd+F on Mac) to jump directly to matching words across all processed pages.
Are my confidential contracts or legal scans uploaded to any cloud server?
No. Every stage of the pipeline—PDF page rendering via PDF.js, character recognition via WebAssembly OCR, and searchable PDF re-assembly via PDF-Lib—executes locally inside your browser memory.
Can I also convert JPG or PNG document scans into a searchable PDF?
Yes. In addition to existing PDF files, you can drop photographed pages or scanned images (JPG, PNG, WebP) into the queue and compile them into a unified searchable PDF or export the recognized text as a .TXT file.
Can I edit or copy the recognized text before downloading the searchable PDF?
Yes. As soon as OCR finishes, the extracted text for each page is displayed in an interactive editor where you can review, copy to your clipboard, download as a .TXT file, or export the compiled Searchable .PDF.
