手寫轉PDF

The tool uses Tesseract.js, an open-source OCR engine that runs entirely in your browser. It recognises text from your handwritten images and converts it to digital characters. It works best on clear, printed-style handwriting. Heavy cursive may produce less accurate results.

Clean Scan enhances your handwriting images (contrast, sharpness, background removal) and bundles them into a professional PDF — no text recognition involved. Digital Text — Same Layout uses OCR to replace handwritten words with typed text at the same positions. Digital Text — Reflowed extracts all text via OCR and re-typesets it as clean paragraphs with your chosen font.

No. Everything runs 100% in your browser using client-side JavaScript, Canvas API, and Tesseract.js. Your images and PDFs never leave your device. This makes it safer and more private than server-based alternatives.

You can upload PDF, JPG, JPEG, PNG, and WebP files. Multi-page PDFs are automatically split into individual pages. You can also upload multiple images at once.

Accuracy depends on handwriting clarity. Neat, printed-style handwriting typically achieves 85-95% accuracy. Cursive or messy handwriting may be less accurate. The Clean Scan mode (no OCR) always produces perfect results since it preserves the original handwriting.

Yes. You can adjust contrast (50-200%), brightness (-50 to +50), sharpness (0-100%), and toggle background removal, grayscale, and pure black & white mode. There's also a threshold slider for fine-tuning B&W conversion.

There's no hard limit. The tool processes each page individually using your browser's resources. For very large documents (100+ pages), processing may take a few minutes. The progress indicator shows the status.

Background removal whitens the paper background while preserving ink strokes. It's especially useful for photos of handwriting on coloured or off-white paper, removing shadows, and cleaning up scanned pages with visible paper texture.
