The quality of OCR output depends heavily on the quality of the input image. Use high-resolution images whenever possible, ideally 300 DPI or higher for scanned documents. Ensure the text is well-lit and the image is not blurry or skewed. Good contrast between the text and background makes a significant difference in accuracy. Dark text on a light background works best. If you are photographing a document with your phone, hold the camera steady and ensure even lighting without shadows falling across the text. For multi-column layouts like newspapers or academic papers, consider cropping to one column at a time for more accurate results. Printed text is recognized far more reliably than handwriting, though neat block-letter handwriting may produce usable results. If the initial extraction misses some text, try adjusting the image brightness and contrast before re-processing.
Our OCR tool supports 10+ languages including English, Spanish, French, German, Portuguese, Chinese (Simplified), Japanese, Korean, Hindi, and Arabic. Select your language from the dropdown before processing to get the most accurate results for that language's character set.
No. All OCR processing happens entirely in your browser using Tesseract.js. Your images never leave your device, and no data is transmitted to any external server. This makes the tool safe for extracting text from sensitive documents, receipts, and personal papers.
All common image formats are supported including JPG, PNG, BMP, WebP, and GIF. For best OCR results, use a clear, high-resolution image with good contrast between the text and background. Scanned documents at 300 DPI or higher produce the most accurate text extraction.
Use high-resolution images with clear, sharp text for the best accuracy. Ensure good contrast between the text and the background. Straight, well-lit images work better than skewed or shadowed ones. Printed text is recognized more accurately than handwritten text. If possible, crop the image to include only the text area before processing.
The OCR engine can attempt to read handwritten text, but accuracy varies significantly depending on handwriting legibility. Neat, printed-style handwriting produces better results than cursive. For handwritten content, you may need to review and correct the extracted text manually. Printed and typed text consistently produces the most reliable results.
