PDF OCR (Optical Character Recognition) scans the visual content of a PDF or image and converts it into selectable, searchable, and copyable text. Our tool renders each page into a high-resolution image and runs it through the Tesseract.js OCR engine — entirely in your browser, with no server uploads.
Yes — that is exactly what it is designed for. If you have a scanned document, a photographed contract, or any image-based PDF where text is not selectable, our OCR tool will read and extract every line of text from it.
We support PDF, JPG, PNG, WebP, TIFF, and BMP files. Multi-page PDFs are fully supported with page-by-page extraction.
100% safe. PDFWorld OCR runs entirely inside your browser using Tesseract.js, a WebAssembly-based OCR engine. Your PDF or image is never uploaded to any server.
Accuracy depends on the quality of the original scan. For clean, high-resolution scans of printed text, the engine typically achieves 95–99% accuracy. Use the 3× render scale option for low-quality scans. The confidence score shown after OCR gives a real-time accuracy estimate.
Over 50 languages are supported, covering Latin, Indic, CJK (Chinese, Japanese, Korean), Arabic, Hebrew, Persian, Cyrillic, Greek, Thai, Burmese, Khmer, and more. You can also select multiple languages simultaneously for multilingual documents.
Yes. Select up to 4 languages from the language panel and Tesseract will recognize text from all of them simultaneously. This is ideal for documents that mix English with Hindi, or French with Arabic, for example.
The render scale controls the resolution at which PDF pages are converted to images before OCR. Higher scale (3×) means more pixels and better accuracy for small or faded text, but takes longer. 2× is the balanced default for most documents.
Yes. Use the Page Range setting to specify a start and end page. Only those pages will be rendered and processed, saving time for large documents where you only need a section.
Yes. Click the Cancel button that appears during processing. The current page will finish its recognition pass and then the job will stop gracefully.
Yes. Many users use our OCR tool to extract text from Aadhaar cards, PAN cards, voter IDs, and other government-issued documents. Since processing is entirely client-side, your sensitive documents are never transmitted over the internet.
