Use Keyboard Shortcuts to Quickly Locate Fonts

Since Acrobat does not have a bulk font-change feature for separate OCR boxes, use keyboard inputs in the font dropdown to speed up manual editing.

When Acrobat performs OCR on a scanned book, it often separates paragraphs and lines into distinct bounding boxes to preserve the original layout. This prevents you from selecting all text at once to change the font.

1
Enter Edit Mode

Open your scanned PDF in Adobe Acrobat and click on the 'Edit PDF' tool in the right-hand pane.

2
Select the Text Box

Click inside the specific OCR text box where you want to change the font.

3
Open the Font List

Locate the Format panel on the right side of the screen and click on the font dropdown menu.

4
Search via Keyboard

Type the exact name of your desired font or press its initial letter on your keyboard to instantly jump to it, rather than scrolling manually.

Acrobat Limitation: Acrobat does not offer a shortcut to switch fonts across all OCR text boxes simultaneously. Manual adjustment per box is required in Edit PDF mode.

Frequently Asked Questions

Can I select all text in a PDF to change the font at once in Acrobat?

In scanned PDFs with multiple OCR text boxes, Acrobat does not allow you to select text across different bounding boxes to change the font simultaneously. You must edit them individually or convert the file to a Word document for bulk editing.

Why does Acrobat create separate text boxes when editing scanned PDFs?

During the OCR (Optical Character Recognition) process, Acrobat attempts to preserve the exact original layout and typography of the scanned page, which often results in text being fragmented into multiple separate text boxes.

What is the fastest way to format a scanned book?

The most efficient method for extensive formatting, such as changing fonts across an entire scanned book, is to export the PDF to a Word document format (.docx), apply global font changes in a word processor, and then save it back as a PDF.
