The most common questions are which languages are supported and whether the image is uploaded. Six languages are supported, the image is never uploaded, and the OCR files come from this site rather than a third-party CDN. The FAQ below also covers confidence, editing, saving as .txt and large photos.
Is my image uploaded to a server when I use this OCR tool?
No. Text recognition runs in your browser using Tesseract.js, and your image and the extracted text are never sent anywhere. The OCR engine and the language data (about 1 to 3 MB per language) are served by this site itself rather than a third-party CDN, and your browser caches them after the first run.
Which languages does it support?
English, Urdu, Arabic, French, German and Spanish. Choose the language of the text before clicking Extract Text; each run reads one language. There is no automatic language detection or translation.
What does the confidence figure mean?
Recognition confidence shows how sure the engine was about the characters it chose, from 1 to 100%, labelled High, Medium or Low. It is not the same as accuracy, so always read the result. Where the engine is unsure about individual words, the tool also tells you how many, so you know where to check. If the engine returns no usable confidence, the tool says Not available instead of showing 0%.
Can I edit the extracted text?
Yes. The result appears in an editable box, so you can fix recognition errors. Editing never re-runs OCR, and Restore OCR text brings back the original result. If you run Extract again, the text in the box is replaced.
Can I download the text as a file?
Yes. Download .txt saves exactly the text in the box (including your edits) as a UTF-8 text file named after your image, for example receipt.jpg becomes receipt-ocr.txt. Urdu, Arabic and accented letters are preserved. Copy Text puts the same text on your clipboard.
Can this tool read handwritten text?
Not reliably. Tesseract.js, the OCR engine behind this tool, is built for machine-printed and typed text. Handwriting recognition is a different problem this tool doesn't target, so results on handwritten notes are often garbled or incomplete.
What happens with a very large photo?
A photo larger than about 4000 pixels on its longest side or about 12 megapixels is scaled down before it is read, and the tool tells you so. Your original file is not changed. Photos saved sideways with a rotation tag are turned upright first. An image of more than about 150 megapixels is refused with a message.
Why did I get an error or no text extracted?
The upload step rejects anything that isn't an image file. If a valid image fails to produce text, common causes are the wrong language selected, low resolution, heavy blur or glare, handwritten content, or a genuinely blank image - try the right language and a clearer printed-text image. If the page says a language (for example Urdu) could not be loaded, click Try again. A run that takes longer than two minutes is stopped with a message, and your image stays in place.
Can I replace the image or drag one in?
Yes. Drag one image onto the upload area or onto the page, or use Replace image at any time. Replacing the image clears the old text and confidence. Clear removes the image and the text.
