Extract text from scanned or image-based PDFs using browser-based OCR. Supports English and Indian languages.
PDF only · Processed entirely in your browser
Supported languages: English, Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati.
Yes — select your language before starting. Accuracy is 70–85% for Indian languages. Always verify important extracted text against the original, especially numbers, names, and dates.
OCR analyses every pixel on every page using your device CPU. Server-based tools use dedicated GPU hardware in datacentres. Browser OCR is slower but keeps your document completely private — it never leaves your device.
Tesseract.js has very limited handwriting recognition. For clearly printed or typed scanned documents it works well. For handwritten documents, results will be poor.
No. Everything runs in your browser using Tesseract.js and PDF.js. Your PDF is loaded into browser memory and never transmitted anywhere.
Yes, but it will take 15–40 minutes. We recommend using Split PDF to divide the document into 50-page chunks first for better reliability.
OCR runs entirely in your browser using Tesseract.js — your scanned documents are never uploaded to any server. Scanned Aadhaar cards, government letters, court orders, and medical reports that you need to make searchable or extract text from are processed locally without any data leaving your device.
No account is required. All eight supported languages, both output modes, and all quality settings are freely available without registration. There is no page limit and no document count cap — run OCR on a single scanned page or a multi-page government gazette with the same tool.
The tool works on any device with a modern browser. Process a scanned document on your phone to make it searchable before forwarding, or OCR a batch of archived reports on your desktop to enable text search across your document library. No specialist software or operating system is required.
Accuracy depends on scan quality and font clarity. For clean, high-resolution scans of printed text in Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, or Gujarati, Tesseract typically achieves 85–95% character accuracy. Handwritten text, very small fonts, or faded prints reduce accuracy significantly. Always select the correct language before starting — running English OCR on a Hindi document will produce meaningless output.
Plain Text extracts all recognised characters into a .txt file — useful for copying into Word, pasting into forms, or feeding text into other tools. Searchable PDF keeps the original page images exactly as they are and adds an invisible text layer beneath them. The document looks identical to the original scan but the text is now selectable, copyable, and findable with Ctrl+F in any PDF reader.
Each page takes 3–8 seconds depending on page resolution, content density, and your device's processing speed. A 10-page scanned document typically completes in 30–60 seconds. Keep the browser tab active and in the foreground during processing — some mobile browsers throttle JavaScript execution for background tabs, which can significantly slow OCR or cause it to stall.
Digital PDFs created by Word, Excel, or a PDF printer already contain a selectable text layer — OCR is not needed and would not improve them. The tool detects this and warns you before running unnecessary processing. If you need to extract text from a digital PDF, use the PDF to Word tool or the PDF to Excel tool instead.
