Question 1

What languages does OCR support?

Accepted Answer

Our OCR tools support English, Simplified Chinese, Japanese, and combined English+Chinese recognition. The OCR engine uses Tesseract.js with WebAssembly for accurate text extraction.

Question 2

Can I extract text from scanned PDFs?

Accepted Answer

Yes! The OCR tool accepts both images and PDF files. For PDFs, each page is rendered as an image and then processed through OCR to extract the text content.

Question 3

How accurate is the OCR?

Accepted Answer

OCR accuracy depends on image quality, font clarity, and language. For clear printed text, accuracy typically exceeds 95%. Handwritten text and low-resolution images may have lower accuracy.

Question 4

What is the difference between PDF text extraction and OCR?

Accepted Answer

PDF text extraction pulls text that is already digitally embedded in the PDF (selectable text). OCR is for scanned documents or images where text is part of the image and needs to be recognized by AI.

Question 5

Can I convert a TXT file to PDF?

Accepted Answer

Yes, the TXT to PDF tool converts plain text files into formatted PDF documents. The text is properly laid out with consistent formatting for easy reading and sharing.

Question 6

Is my document data safe?

Accepted Answer

Completely safe. All text extraction and OCR processing happens in your browser using WebAssembly. Your documents never leave your device and are not sent to any external server.
