A photo, screenshot, or scan containing text

Text recognition runs entirely in your browser using Tesseract.js (WebAssembly OCR). Your image is never uploaded to a server.

About this tool

Retyping text from a photo, screenshot, or scanned page is slow and error-prone. This image to text tool extracts text directly from an image using Tesseract.js, an open-source OCR (optical character recognition) engine that runs entirely in your browser via WebAssembly — no image is ever uploaded to a server. Choose from over a dozen supported languages, then copy or download the extracted text.

How to use it

  1. 1Click the upload area or drag an image containing text onto it.
  2. 2Choose the language the text is written in.
  3. 3Wait for recognition to finish — a progress indicator shows the current stage.
  4. 4Copy the extracted text, or download it as a .txt file.

Common mistakes to avoid

  • Using a blurry, low-resolution, or heavily skewed photo — OCR accuracy depends heavily on image clarity and a roughly horizontal line of text.
  • Selecting the wrong language before recognition — pick the language that matches the text in the image for accurate results.
  • Expecting perfect accuracy on handwriting — this OCR engine is optimized for printed and typed text, not handwritten script.

Use cases

  • Pulling a quote or paragraph out of a screenshot without retyping it.
  • Digitizing text from a scanned document or photographed page.
  • Extracting text from a photo of a sign, label, or receipt.

Frequently asked questions

Is my image uploaded to a server?

No. Text recognition happens entirely in your browser using Tesseract.js, an open-source WebAssembly OCR engine. Your image never leaves your device.

Why did the first recognition take longer than expected?

The OCR engine downloads a language-specific data file the first time you use a given language. Once downloaded, recognition in that language is noticeably faster.

Can it read handwriting?

It's optimized for printed and typed text. Handwritten text — especially cursive or stylized handwriting — will produce much less reliable results.
