How to Change or Update Saved PDF Files

By Tammy Clevenger

To change or update saved Portable Document Format (PDF) files, the Adobe Acrobat application is required. The Adobe Acrobat application includes many tools to create and modify PDF documents. Using the Optical Character Recognition (OCR) function in Acrobat, a PDF document scanned as an image may be converted to an editable, modifiable document with rendered and formatted text. Using the Advanced Editing tools in Acrobat, PDF documents may be easily changed and updated.

Things You'll Need

  • Computer with Adobe Acrobat installed

Step 1

Click the Windows “Start” button and select “All Programs.”

Step 2

Click on the “Adobe Acrobat” program icon to open the application.

Step 3

Click the “File” option from the top navigation bar in the Acrobat interface.

Step 4

Select “Open” and navigate to the PDF file to update. Double-click on the PDF and click “Open.” The PDF will open in Acrobat.

Step 5

Run the OCR scan on the document. To do this, click “Document,” and then click “Recognize Text Using OCR.” The OCR scan will be performed on the document. If the document is a scanned image, the OCR scan will recognize each image character and convert the character to text. The OCR scan will present input boxes where the text is not recognized. If the PDF document already contains rendered text, a notification will appear.

Step 6

Input text for each ambiguous word or character. Click “OK” to continue the scan. Repeat until the complete document has been scanned.

Step 7

Click “OK” to close the OCR scanning feature.

Step 8

Click the “Tools” option from the top navigation bar and select “TouchUp Text Tool.” Use this tool to select and edit text.

Step 9

Make all necessary edits to the PDF.

Step 10

Click “File” and then click “Save” to save the PDF document with changes.
