OCR PDF
Turn a scanned PDF — one that's really just a photo of a page, with no real text underneath — into something searchable. This tool renders every page as an image, then runs optical character recognition (OCR) on it directly in your browser to recognize the text. You get two options: a plain-text download of everything it found, or a searchable PDF that looks identical to your original scan but has an invisible, selectable text layer underneath. OCR is the heaviest tool on Toolify — expect roughly 5–20 seconds per page, so multi-page documents can take a while.

OCR runs entirely in your browser and is slow — roughly 5–20 seconds per page — so multi-page documents can take a while. Keep this tab open until it finishes.
How to use the OCR PDF
- 1Select a scanned PDF. Choose the PDF you want to make searchable.
- 2Run OCR. Each page is recognized in your browser — this can take a while for multi-page files.
- 3Download text or a searchable PDF. Get a .txt file of the text, or a PDF with an invisible searchable layer.
Frequently asked questions
Why is OCR so much slower than other tools?
Recognizing text from an image is computationally expensive — the engine analyzes shapes across the entire page to identify letters and words. It runs entirely in your browser with no server to offload the work to, so expect roughly 5–20 seconds per page.
How accurate is the recognized text?
It depends heavily on scan quality. Clean, high-resolution scans of printed text are usually recognized very accurately; low-resolution, skewed, or handwritten text produces more errors. Always spot-check important details like names and numbers.
What is a "searchable PDF" exactly?
It's your original scanned page, unchanged visually, with the recognized text placed invisibly on top in the exact position of each word. It looks like a scan but you can select, search, and copy text from it in any PDF viewer.
Is my scan uploaded anywhere?
No. Rendering and recognition both happen entirely in your browser — this matters especially for scans, which are disproportionately likely to contain sensitive documents.
