# PDF Text Extractor
Simple MERN webapp to extract text from an uploaded PDF using OCR.
## Technologies
- React for the frontend
- Express for the backend
- Multer for handling file uploads
- pdfjs-dist and pdf-parse for PDF parsing
- Tesseract.js for OCR
**NOTE:** If the text data is embedded directly in the PDF (the PDF contains searchable text), `pdf-parse` is used directly to extract the text. If the text data is not directly embedded (the PDF contains scanned images or non-searchable text), each page is converted to an image using `pdf.js` and then sent to `Tesseract.js` for OCR.
