图像到文本在线 — 在浏览器中免费 OCR
无需上传即可从任何图像中提取文本。我们的浏览器基于客户端运行的 OCR 工具，速度快、私密且完全免费。
Optical Character Recognition (OCR) lets you extract editable text from images — scanned documents, screenshots, photos of whiteboards, or receipts.
ConvertCraft runs OCR entirely in your browser using Tesseract.js, a WebAssembly port of the industry-standard Tesseract OCR engine. Your images stay on your device at all times.
To extract text: 1) Open the Image to Text tool. 2) Drop an image file (PNG, JPG, WebP, TIFF, BMP). 3) Select the language(s) present in the image. 4) Click Extract and copy or download the recognized text.
The tool supports over 100 languages including English, Spanish, French, German, Arabic, Chinese, Japanese, and Korean. For best results, use clear images with good contrast and standard fonts.
OCR accuracy depends on image quality. Scanned documents at 300 DPI typically achieve 95%+ accuracy. Photos of printed text with good lighting also work well. Handwritten text recognition is experimental but improving.
