圖片轉文字 — 免費OCR,無上傳,100%私有
直接在瀏覽器中使用OCR從圖片中提取文字。您的檔案永遠不會離開您的裝置。
OCR準確率取決於圖片品質。為獲得最佳效果，請使用對比度高、文字清晰的圖片。
如果圖片中包含照片或圖形，請選擇「二值化」以抑制非文字區域。「灰度」或「反色」可幫助處理低對比度或深色模式截圖。
拖放圖片到此處,從剪貼簿貼上,或點選瀏覽

使用步驟
- Drop or Paste Screenshot: Drag your PNG/JPG/WebP screenshot into the drop zone, or use Ctrl+V / Cmd+V to paste from clipboard. Screenshots from Windows Snipping Tool, macOS screenshot, Greasemonkey, or browser capture extensions all work.
- Pick OCR Language: Select the language(s) your screenshot is in. English is selected by default. Multi-language packs (e.g. English + Chinese) are supported for mixed-language screenshots.
- Run OCR: Click 'Extract Text'. The Tesseract.js engine scans the image in your browser via WebAssembly. Most screenshots OCR in under 3 seconds.
- Copy or Download: Read the extracted text in the result panel. Copy to clipboard with one click, or download as a .txt file. Formatting is preserved best-effort; for tables, use the Image to Text tool with structured output mode.
為何選擇此工具
- 100% Local Processing: Files are processed entirely in your browser using JavaScript — never uploaded to any server.
- No Limits: No file count or file size restrictions. Process as many files as your device can handle.
- No Sign-up: Free forever, no account needed, no email required. Open the page and start.
- Private by Design: Nothing is sent to any server. Close the tab and your files are gone forever.
常見問題
How do I extract text from a screenshot?
Drop the PNG/JPG into our Image to Text tool, click 'Extract', and the text appears in seconds. The whole process runs in your browser via Tesseract.js — your screenshot never leaves your device. Works for code snippets, chat logs, error messages, and any text trapped in an image.
Is there a free screenshot-to-text tool?
Yes — our Image to Text tool is 100% free with no sign-up, no daily limits, no watermarks. We support 10+ OCR languages including English, Spanish, French, German, Chinese (Simplified & Traditional), Japanese, Korean, Portuguese, Russian, and Arabic.
Can I paste a screenshot from clipboard?
Yes — use Ctrl+V (Windows/Linux) or Cmd+V (macOS) anywhere in the tool to paste from clipboard. Our drop zone accepts pasted image data without needing to save the screenshot first.
Does it work with high-DPI screenshots?
Yes. Tesseract.js handles high-resolution images well. We auto-scale very large screenshots before OCR for speed. For best accuracy on small text, use the original resolution rather than a resized version.
What about code in screenshots?
Our OCR handles monospace fonts well. The extracted text preserves basic spacing but you may need to re-indent code in your editor. For exact code-block OCR, paste directly into a code-aware viewer like VS Code with image-to-code extensions.
Is my screenshot uploaded to any server?
No. The OCR runs in your browser via Tesseract.js WebAssembly. Your screenshot is processed locally and never sent to any server. This is critical for sensitive screenshots (private chats, financial data, internal dashboards).
Can it OCR multiple screenshots at once?
Yes — drop several image files (PNG/JPG/WebP) into the drop zone. Our tool processes them in batch and shows each result separately. You can copy them individually or download as a combined .txt file.
