Add an invisible text layer to a scanned PDF so search and copy work while the visible page stays exactly the same.

How it works
Each page is rendered and OCR'd. The recognised text is drawn as an invisible layer (opacity 0.01) on top of the page image. Search and copy pick up the text; visually nothing changes.
Privacy
All OCR runs in your browser. No upload.
Known limitations
- Alignment of the invisible text may not match the visual image exactly.
- Very slow on long PDFs — limit pages for a first pass.
- Handwriting is poorly recognised.
Frequently asked questions
What does searchable mean?
A searchable PDF has a hidden text layer over the scanned image. Ctrl+F and text selection work while the visual content stays identical.
