What is OCR (Optical Character Recognition)?
OCR technology extracts text from images by analyzing visual patterns and converting them into machine-readable characters. It supports printed text, screenshots, scanned documents, and photos.
How to Use This OCR Tool
Click the upload area or drag an image onto it. You can also paste an image from clipboard (Ctrl+V). Once the image is loaded, click Recognize to extract text. The result will be displayed with confidence scores.
Supported Image Formats
This tool supports common image formats including PNG, JPEG, BMP, and WebP. For best results, use clear, high-resolution images with good contrast. The recognition works entirely in your browser using Tesseract.js.
▶Does this tool send my images to a server?
No. All OCR processing happens locally in your browser using Tesseract.js. Your images are never uploaded to any server.
▶What languages are supported?
The OCR engine supports multiple languages including English, Chinese, Japanese, Korean, and many European languages. Recognition accuracy depends on image quality and text clarity.
▶Why is the recognition accuracy low?
Low accuracy can be caused by blurry images, low resolution, complex backgrounds, unusual fonts, or handwritten text. Try using a clearer image with better lighting and contrast.
