Google Docs now officially supports importing scanned
What Google launched as an experimental feature for the
Documents List Data API last year is now available on the
upload page: check the "Convert text from PDF or image
files to Google Docs documents", upload your scanned images
(JPEG, GIF, PNG) or PDFs, and Google Docs will extract text
and formatting from the scans for you to edit away.
Google is using Optical Character Recognition (OCR) that
was developed by the Google Books team. OCR works best with
high-resolution images, and not all formatting may be
preserved. The original images will be included in the new
document to make it easier for you to correct mistakes.
Supported languages include English, French, Italian,
German and Spanish, with more languages and character sets
on their way.
