Edit Text in Scanned Documents
Scanned documents are usually images, which means they cannot be modified directly. To edit the text in a scanned document, it has to be made editable. This is where OCR tools are of use.
OnlineOCR does just that. It's a site which converts scanned images of documents and gives you the editable text.
OnlineOCR accepts pdf, tiff, jpg, png, bmp, pcs, zip files as input. Output formats supported are plain text, rtf, pdf, word, excel and html. It supports 28 languages. The website also claims to preserve the formatting in the original file. However, I haven't tested that yet. Till then, enjoy!
