What image formats are supported?

PNG, JPEG, WebP, BMP, and GIF are supported by Tesseract.js.

Is my image uploaded anywhere?

No. Tesseract.js runs entirely in your browser via WebAssembly. Your images never leave your device.

Why is the confidence low?

Low-resolution, blurry, or stylised-font images reduce accuracy. Try cropping to just the text area and increasing contrast before uploading.

Which languages are available?

English is the default. Other options include French, German, Spanish, Chinese (Simplified), and Japanese — language data is downloaded on demand.

このツールについて

Image Text Extractor runs Tesseract.js (v5) directly in your browser to perform optical character recognition on uploaded images. Drag-and-drop or click to upload a PNG, JPG, or WEBP file, choose the recognition language, and watch a live progress bar as the text is extracted. Results appear in an editable textarea with a one-click Copy button. A confidence score lets you know how reliable the extraction is. No image is ever sent to a server — all processing happens locally via WebAssembly.
