OCR PDF uses optical character recognition to turn a scanned document into a searchable, selectable PDF. After processing, you can find words with search, copy text and use screen readers, while the page still looks like the original scan. Your file never leaves your device: the work happens in your browser, with no upload and no account. Recognition runs on your device, so the first run may take a moment, depending on page count.
It reads the text in page images and adds an invisible text layer, so the document becomes searchable and selectable.
Accuracy is best on clear, straight scans. Blurry or skewed pages produce more errors.
No. Recognition runs in your browser.
Text recognition is heavy work, and doing it locally takes longer than on a server.
