Extract text from images using optical character recognition

Cómo usar Imagen a Texto (OCR)

  1. 1

    Upload your image

    Drag and drop or click to select a JPEG, PNG, or WebP file containing text.

  2. 2

    Click Extract Text

    The OCR engine downloads the language model on first use (cached for subsequent runs), then analyses your image.

Preguntas frecuentes

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
What languages are supported?
Currently English is supported. Tesseract supports over 100 languages — additional language packs may be added in future updates.
Why does it download a model on first use?
The OCR engine requires a trained language model (~10 MB for English). This is downloaded once from the jsDelivr CDN and stored in your browser's IndexedDB cache. After the first download, the tool works instantly and even offline.
How accurate is the OCR?
Tesseract produces excellent results on clearly typed, high-contrast text. Accuracy drops with handwriting, decorative fonts, low resolution, skewed scans, or noisy backgrounds. For best results, use a straight, well-lit photo with dark text on a light background.
Is there a file size limit?
No hard limit — processing happens entirely in your browser. Large images (10 MB+) may take longer on mobile devices, but there is no server-imposed cap.
Can I extract text from PDFs?
Not directly — this tool works with image files (JPEG, PNG, WebP). To extract text from a PDF, use the PDF to Image tool first to convert a page to an image, then run OCR.

¿Qué es Image to Text (OCR)?

Extract text from any photo, screenshot, or scanned document instantly using optical character recognition that runs entirely in your browser. Powered by Tesseract.js — the same open-source OCR engine trusted by developers worldwide — this tool processes your images locally without uploading a single byte to any server. The English language model (~10 MB) downloads once from a public CDN and is cached in your browser for offline use. Drop a JPEG, PNG, or WebP, click Extract Text, and copy or download the result as a .txt file. No sign-up, no watermarks, no limits.

¿Por qué usar Image to Text (OCR)?

  • 100% private — your images never leave your device. OCR runs entirely in your browser using WebAssembly.
  • Offline after first load — the language model downloads once (~10 MB) and is cached. Subsequent uses work without an internet connection.
  • No file size limits — process high-resolution scans and screenshots without artificial caps.
  • Copy or download results as a .txt file in one click.
  • No sign-up, no daily limits, no watermarks. Completely free, forever.

Casos de uso de Image to Text (OCR)

Digitising scanned documents

Extract text from scanned contracts, receipts, invoices, or letters so you can edit, search, and copy the content.

Screenshots and screen captures

Pull text from screenshots of error messages, chat logs, articles, or UI mockups when you can't select it directly.

Book and article excerpts

Photograph a page from a book or printed article and extract the text to quote or reference without retyping.

Whiteboard and handwritten notes

Convert photos of whiteboards, sticky notes, or typed handwritten text into editable digital content.

Consejos y buenas prácticas

  • 💡For best accuracy, use high-contrast images — dark text on a light background. Avoid blurry or low-resolution photos.
  • 💡Crop out irrelevant areas (logos, borders, backgrounds) before running OCR to improve accuracy and speed.
  • 💡The language model is cached after the first download. Subsequent runs are much faster even on slow connections.
  • 💡Tesseract is optimised for printed text. Handwriting recognition accuracy varies — expect best results with clear, block letters.
