OCR PDF
Turn a scanned PDF into a searchable one. The text is recognized in your browser and placed invisibly on top of each page, so the pages look the same but you can search, select and copy the words. Your file never leaves your device.

Make a Scanned PDF Searchable Online for Free
A scanned PDF is only a set of pictures, so you cannot search it or copy anything from it. OCR (optical character recognition) reads the words in those pictures and adds them back to the file as text, right in your browser.
How to OCR a PDF
- Select the scanned PDF, or drop it on the page.
- Choose the language of the text, and a second one if the document mixes two.
- Pick Accurate or Fast, then click Make searchable.
- Download the searchable PDF, or the recognized text as a .txt file.
How it works
Each page is drawn at high resolution and read by an OCR engine. The recognized words are then placed invisibly over the original page at the position where they were found. The scan itself is not recompressed or redrawn, so it keeps its original quality.
Tips for better results
- Choose the right language first. It has the biggest effect on accuracy.
- Use Accurate for small print, tables and older documents.
- Straight, sharp, well-lit scans give the best text. Handwriting is not supported.
