Frequently Asked Questions About Image to Text OCR
Get answers to common questions about extracting text from images using OCR technology.
What is OCR and how does it work?
OCR (Optical Character Recognition) is technology that analyzes images to identify and extract text characters. Our tool uses Tesseract.js, an advanced AI-powered engine that recognizes patterns in images and converts them to machine-readable text with 95%+ accuracy.
Is this image to text converter free?
Yes, completely free! No subscriptions, no hidden fees, no page limits, and no watermarks. Extract text from unlimited images without paying anything or providing an email address.
Are my images uploaded to your servers?
No, never. All OCR processing happens directly in your browser using JavaScript and WebAssembly. Your images never leave your device, ensuring 100% privacy. This makes our tool safe for sensitive documents like IDs, receipts, contracts, and medical records.
What languages does your OCR support?
We support 100+ languages including English, Hindi, Spanish, French, German, Arabic, Chinese (Simplified & Traditional), Japanese, Korean, Russian, Portuguese, Italian, Thai, Vietnamese, and many more. Select your language before processing for best results.
How accurate is the text extraction?
Accuracy ranges from 95-99% on clear, high-contrast images with legible text. Factors affecting accuracy include image quality, text size, font style, background contrast, and image resolution. Follow our tips for best results.
What image formats are supported?
We support all major image formats including JPG/JPEG, PNG, WebP, GIF, and BMP. No file size restrictions, though very large images may take longer to process on mobile devices.
Does it work on mobile phones?
Yes! Our OCR tool is fully responsive and works perfectly on mobile devices. Take a photo with your phone's camera and extract text immediately. Compatible with Chrome, Safari, Firefox, and Edge on Android and iOS.
Can it recognize handwritten text?
Yes, but with limitations. Our OCR works best with clear, legible handwriting. Accuracy for handwritten text is typically 70-85% compared to 95%+ for printed text. Use high-quality images with dark ink on light backgrounds for best results.
How long does OCR processing take?
Processing typically takes 5-15 seconds depending on image size, resolution, and text complexity. The first time you use a language, there's an additional 3-10 second download for language data, which is then cached for offline use.
Can I use this tool offline?
Yes! After the first use of a language, the language data is cached in your browser. You can then use the tool offline without an internet connection, making it perfect for travel or areas with poor connectivity.
