Convert scanned pdf to .txt files using tesseract

Question

I have to convert a `.pdf` file containing scanned images into `.txt` files. The `tesseract ocr` converts only images to `.txt`, but I need to first extract the `.tif` images and then convert it. Can anyone help me with this?

Accepted Answer

Use Imagemagick:

```
convert -density 600 input.pdf output.tif
```

Density is in DPI, from my experience 600 DPI works the best.
