Perguntas frequentes

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.

Casos de uso de Image to Text (OCR)

Digitising scanned documents

Dicas e boas práticas

  • 💡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.
