How to Extract Text from an Image or PDF

Three steps, entirely in your browser — no software installation required.

  1. 1

    Upload Your File

    Drag and drop or click to select an image (PNG, JPEG, WEBP, HEIC) or a PDF. The file is read locally — it never leaves your device.

  2. 2

    Click Extract Text

    The Tesseract.js OCR engine — compiled to WebAssembly — analyses the image and recognises text character by character. A real-time progress bar keeps you informed.

  3. 3

    Copy or Download

    Review the extracted text in the editable panel. Correct any recognition errors if needed, then copy to clipboard or download as a .txt file.

Zero Data Exposure

All OCR processing runs inside your browser. Sensitive documents — invoices, IDs, contracts — are never uploaded to any server.

WebAssembly Speed

Tesseract.js is compiled to WebAssembly, giving you near-native OCR performance without any server round-trip.

Images & PDFs

Accepts PNG, JPEG, WEBP, HEIC photos and PDF documents. PDFs are rendered at high resolution before text extraction.

Editable Output

The extracted text is fully editable so you can correct errors on the spot, then copy or download the final result.

Why Use a Browser-Based OCR Tool?

Traditional OCR services — Google Drive, Adobe Acrobat, ABBYY — send your document to a remote server for processing. If that document is a payslip, medical record, ID scan, or confidential contract, that upload creates a real privacy risk.

A browser-based OCR tool eliminates that risk entirely. By running Tesseract.js directly in your browser via WebAssembly, all text recognition happens on your own hardware. Nothing is transmitted, nothing is stored, and the result is instant — no waiting for server processing or file transfer.

What Can You Do with Extracted Text?

Once text has been extracted you can copy it straight to the clipboard and paste it into any application — Word, Google Docs, a spreadsheet, or a translation tool. Alternatively, download the result as a plain .txt file for archiving or further processing. The output panel is editable, so you can correct any OCR errors before exporting.

Frequently Asked Questions

Is my document kept private when using this OCR tool?+
Yes, completely. Tesseract.js runs entirely inside your browser using WebAssembly. Your images and PDFs are never sent to any server — not ours or anyone else's. The moment you close the tab, nothing is retained.
What file formats does the OCR tool support?+
The tool accepts common image formats (PNG, JPEG, WEBP, ICO, HEIC) and PDF files. For PDFs, the first page is rendered at high resolution and passed to the OCR engine.
How accurate is the text extraction?+
Accuracy depends on the quality of the source image. Clean, high-resolution scans of printed text typically achieve 95%+ accuracy. Handwritten text, low-contrast images, or heavily skewed documents may produce lower accuracy. You can edit the extracted text directly in the results panel.
Can I extract text from multiple pages of a PDF?+
Currently the tool processes the first page of a PDF. For multi-page documents, you can convert individual pages to images and run them one at a time. Multi-page support is on the roadmap.
Does the tool work offline after the first load?+
Once the page and the Tesseract.js WebAssembly bundle have loaded, the OCR engine can run without an active internet connection. This makes it suitable for air-gapped or restricted-network environments.
Can I edit the extracted text?+
Yes. The output panel is a fully editable textarea. You can correct recognition errors, delete unwanted lines, and then copy the final text to your clipboard or download it as a .txt file.
