About Image OCR
This image OCR tool uses Tesseract.js to extract text from images locally. Tesseract.js is a WebAssembly port of Google Tesseract, supporting over 60 languages (Chinese, English, Japanese, Korean). Language packs load on demand from CDN and cache in IndexedDB. Recognition uses an LSTM neural network for text-line detection, character segmentation, and semantic inference, outputting confidence scor

FAQ
What languages are supported?
Over 60 languages including Simplified Chinese, Traditional Chinese, English, Japanese, Korean, French, and German. Language packs load on demand from CDN and cache locally.
What is the recognition accuracy?
Over 90% for clear screenshots and scans. Photos are affected by lighting, angle, and blur. Use high-resolution, evenly lit images for best results.
Is slow first-time loading normal?
Yes. The first use of a language downloads its data pack (about 10 to 15MB) from CDN, cached in IndexedDB for subsequent use without re-downloading.
Can it recognize handwriting?
Handwriting recognition accuracy is low; Tesseract is optimized for printed text. Use dedicated handwriting recognition tools for handwriting.
Are images uploaded?
No. All OCR recognition runs locally via the Tesseract.js WebAssembly engine; images never leave your device, safe for sensitive credentials and documents.
