About OCR — Image to Text

Optical Character Recognition (OCR) is the technology that converts images of text — scanned documents, screenshots, photos of signs, or any image containing readable characters — into actual machine-readable and editable text. It eliminates the need to manually retype text visible in images, saving significant time when working with scanned contracts, receipts, printed notes, or screenshots of content that cannot be selected.

Our OCR tool runs Tesseract — the leading open-source OCR engine originally developed by HP and now maintained by Google — as a WebAssembly module directly in your browser. This is significant: your images are never uploaded to any server. Tesseract supports 12 languages including English, Portuguese, Spanish, French, German, Italian, and more, with language data downloaded once and cached locally for subsequent uses.

Accuracy depends heavily on image quality. High-contrast, sharply focused images with clean typography produce near-perfect results. Handwritten text, stylized fonts, poor lighting, and heavy compression artifacts reduce accuracy. For best results, use images where text is clearly legible to the human eye — if you can read it easily, Tesseract can usually extract it accurately.

How to Use OCR — Image to Text

  1. 1Click "Upload Image" and select a PNG, JPG, WebP, or other image file containing text.
  2. 2Select the language of the text in the image from the language dropdown.
  3. 3Click "Extract Text" to start the OCR process — the first run may take a moment to load language data.
  4. 4The extracted text appears in the output panel and is editable for corrections.
  5. 5Click "Copy" to copy the extracted text or "Download" to save it as a .txt file.

Use Cases

  • Extract text from a scanned document, invoice, or receipt to make it editable
  • Copy text from a screenshot of a website, PDF, or article that cannot be selected
  • Digitize printed notes, textbook pages, or printed documents for editing or searching
  • Read and capture text from photos of signs, menus, product labels, or printed materials
  • Convert image-based PDFs (scanned documents) into searchable text for archiving
  • Extract data from images of tables or forms for import into a spreadsheet

Tips

  • High-contrast, sharp images produce significantly better OCR accuracy than blurry or low-resolution ones
  • The first recognition run may be slower as the language data file downloads and caches locally
  • Select the correct language before starting — accuracy drops significantly with the wrong language model
  • Increase image resolution or zoom before taking a screenshot to improve OCR quality
  • Handwritten text has much lower accuracy than printed text — results may need manual correction
  • For multi-column documents, the extracted text follows reading order but may need reformatting

Frequently Asked Questions

PNG, JPG/JPEG, WEBP, BMP, GIF and TIFF. For best results use high-resolution images with clear, high-contrast text.

English, Portuguese, Spanish, French, German, Italian, Dutch, Polish, Russian, Japanese, Chinese (Simplified) and Arabic.

For clean, printed text with good contrast, expect 95–99% accuracy. For handwritten text or low-quality scans, accuracy will be lower.

No. OCR runs entirely in your browser using WebAssembly (Tesseract.js). Your images never leave your device.

Not directly — the tool accepts image files. Convert PDF pages to images first, then run OCR on each image.

On first use, the OCR engine (~10 MB) and language data (~4 MB) are downloaded and cached. Subsequent recognitions start immediately.
