Are my uploaded images sent to any external server?

No. All Optical Character Recognition (OCR) algorithms execute 100% locally inside your browser memory using WebAssembly and Tesseract.js. Your pictures, documents, and extracted text never leave your device.

What image formats and languages are supported?

The converter supports all major image formats including PNG, JPG/JPEG, WebP, GIF, BMP, and TIFF. Supported languages include English, Romanian, Spanish, French, German, Italian, Portuguese, Chinese, and Japanese.

How can I maximize OCR accuracy on difficult images or dark screenshots?

Use our built-in enhancement toggles: enable Grayscale and High Contrast for faded photos or receipts, use Invert Colors for dark mode screenshots with white text on dark backgrounds, and use the 90° Rotation tool to straighten sideways text.

Can I paste images directly from my clipboard?

Yes! Simply press Ctrl + V (or Cmd + V on Mac) anywhere on the page to paste a screenshot or copied image directly into the OCR studio.

Can I convert the extracted text into CSV or comma-separated lists?

Yes. Once the text is extracted, you can use our 1-click "Comma Delimited" button or click "Open in Comma Separator" to transform columns of extracted words or IDs into SQL IN clauses or CSV formats.

100% Client-Side Privacy: Why Zero Server Uploads Matter
