Yes, it performs OCR on images (jpg, tiff, bmp, etc) and PDF's. OCR is perfomed by well-known open-source library Tesseract. We tuned it to achieve best perfomance and quality on scanned documents. You can easily find all files on which OCR was perfomed with tags:ocr query

I miss XXX language analyzer. Can you add it?

Yes, please create an issue on GitHub.

Are you going to add UI localizations?

We're working on it. Be patient.

What is the maximum file size it can handle?

It's limited by amount of RAM on your machine, typically 500MB. It's an awesome result, as typical document managment systems offer 30MB maximum file size to be processed.
