If your document has too many recognition errors to fix, you may need to find a born-digital version (check the Iwasaki Library) or create a higher-quality scan. It’s recommended to use Save As to create a new version of the file. You can ignore any red boxed text that is already recognized correctly. Continue this process until all text is recognized correctly.

Unchecking the Review box or clicking Cancel will return your display to the page image. You can then double-click on any word to place a red box around it and correct its recognition. Doing this will not change your document's appearance to readers. If you check the box for Review recognized text at top left, Acrobat will display the searchable text layer instead of the page image.

There may be recognition errors that are not in red boxes.

Type in the recognized as box to correct as needed, then click Accept to save your edit:
