English by default. Tesseract.js supports 100+ languages — additional language models can be added.
Why does it take a few seconds?
The first use loads the Tesseract OCR engine (~4MB WASM). Subsequent uses on the same page are faster.
What image types work best?
Clear, high-resolution images with printed (not handwritten) text, good contrast, and minimal background noise give the best accuracy.
