If you want to edit a photo text in a file with a .tiff extension, you must covert it to an editable word processing document. Another reason to convert is to keep all files uniform in type and size, because typically, word processing files take up less space (byte-size wise) than graphic files. Additionally, if a .tiff picture file cannot be opened by all intended viewers, commonly used MS Word files may be better suited.
Open the .tiff file from the Paint software program. Select "File" and "Save As." In the "Save In" drop-down list box, select "Desktop" as the place to save the file. In the "Save As Type" box, save it as a file with a ".png" extension. Exit out of Paint. (NOTE: File extension ".png "stands for Portable (Public) Network Graphic)
Open the document from the desktop to verify that it was saved with the new extension.
Right-click on the .png extension file located on the desktop. Select "Covert To," "Microsoft Word Document."
Click through the words that the OCR software does not recognize and either select from: "Ignore," "Ignore All," "Add," "Change" or "Change All." When finished, "Close" out of the OCR dialog box.
Verify your document by viewing it for clarity. The Microsoft Word program will automatically open with the newly created document. (NOTE: Depending on the type of conversion software you have, the new file may display a number "1" at the end of file or any other pre-set document indexing properties.)
