Question 1

Is my image uploaded to a server?

Accepted Answer

No. Text recognition runs entirely in your browser using Tesseract.js, a WebAssembly OCR engine. Your image and the extracted text never leave your device — there is no upload and no network request beyond the one-time OCR engine download.

Question 2

What image formats can I use?

Accepted Answer

Any common image format works, including JPG, PNG, WEBP, and BMP. For best results, use a clear, well-lit, in-focus image — screenshots and flatbed scans typically give the most accurate results.

Question 3

Does this work on handwriting?

Accepted Answer

This tool is optimized for printed text (books, documents, screenshots, signs). Handwriting recognition is a known weak spot for this OCR engine and results will often be inaccurate — for handwritten notes, expect to do manual proofreading.

Question 4

Why does the first extraction take longer than expected?

Accepted Answer

The first time you use this tool with a given language, your browser downloads that language's OCR training data (typically a few megabytes). It's cached afterward, so subsequent extractions in the same language are much faster.

Question 5

What does the confidence score mean?

Accepted Answer

It's Tesseract's own estimate (0-100) of how certain it is about the recognized text. High confidence usually means clean, accurate results; low confidence suggests the image was blurry, low-resolution, skewed, or in an unsupported language, and the output should be proofread.

Question 6

Which languages are supported?

Accepted Answer

English, Spanish, French, German, Portuguese, Italian, Dutch, Russian, Chinese (Simplified), Japanese, Arabic, and Hindi. Pick the language that matches the text in your image before extracting for the most accurate results.

Question 7

The result is empty or wrong — what can I do?

Accepted Answer

Try a higher-resolution image, improve lighting/contrast, straighten any rotation or skew, and make sure the selected language matches the text in the image. Very small text or heavy background noise can also reduce accuracy.
