Scanners that use OCR will create the scanned documents with editable text.Optical Character Recognition (OCR) is a technology that extracts text from images and image-based PDFs, and turns it into editable and searchable text.We've gathered the most popular ones to help the most amount of people.Ĭontinue reading or use our Table of Contents to jump right to the section you need! What to Know Before You Start There are multiple, easy ways to edit a scanned document. It can be frustrating and confusing if you don't have the right tools and the know-how.įortunately, it's easier than you may think. This problem is even more important when the PDF has text that you want to edit. Sometimes we may need to edit our scanned document before it's ready for our needs. Scanning a is easy, but how do you edit a scanned document? To determine if your PDF is fully accessible, you will need to consult with an expert or start to develop your own PDF accessibility.Scanning a paper document is a great way to make a copy of a it, share it with others, or store it long-term. However, it will only alert you to errors detectable by a computer, like missing alt-text, and is not able to accurately assess things like the accuracy or usability of the alt-text or errors in the page reading order. The Accessibility Checker in Acrobat Pro is a good next step in assessing your document. If it passes both, then you may or may not have an accessible document, and more assessment is needed. If your PDF fails either of the two tests above, you will need to remediate it. If you encounter the text “No Tags available” when you open the Tag pane, then your document is not accessible. ![]() Proper conversion processes from programs such as Word will get most elements properly tagged and in the appropriate reading order. PDF tag structure can be assessed within Adobe Acrobat Pro via Document Properties or the Tag panel in the Navigation Pane. A tag allows assistive technology to identify the type of content contained in a PDF, such as paragraphs, images, or tables. Please reach out to the OTL if you need your document to go through OCR in ABBYY Fine Reader. (Please note that OCR programs like ABBYY FineReader can only conduct automated conversions, and the PDF created will most likely require further editing in Acrobat Pro to ensure 100% accuracy). Low quality source documents may need to be run through a program like ABBYY Fine Reader. Adobe Acrobat Pro has an OCR component for high quality source documents. To remediate this, you will need to run the PDF through an optical character recognition (OCR). If the entire page highlights when you click on it, that means the text is not selectable and your PDF is an image. It is an image of text. This can be tested by trying to select text within the PDF.The Adobe Cloud Suite is available for download for DU faculty, students, and staff at no cost and is required for certain processes to assess or improve the accessibility of PDFs. Remediating a PDF file created from an inaccessible Word file, for example, takes much more time than creating an accessible Word file and then saving it as a PDF (do not use print as PDF as this will take away all style settings in the PDF).Īdobe Acrobat Pro is available through the Adobe Creative Cloud Suite. If you have an existing inaccessible PDF file and no longer have access to the source file, it can be remediated for accessibility directly within Acrobat Pro, but it is not always simple task depending on the quality of the source document (other OCR software may be needed for poor quality scans). If either step is missed, the resulting PDF will not be accessible. Secondly, the process of exporting to PDF must be done in a way that preserves the accessibility features of the original file. First, in order to have the best source document, accessibility best practices should be followed when creating the document in the original software. It is important to follow two key steps in creating accessible PDFs. ![]()
