Why Acrobat XI and DC Edit PDF Text Differently
Question details
The user is asking why Acrobat XI and Acrobat DC display and edit PDF text differently, specifically regarding why one creates separate text boxes while the other groups text into a single large box.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Editing existing text within a PDF document using different versions of Adobe Acrobat.
- Observed behavior
- Acrobat XI and Acrobat DC interpret the PDF layout differently, causing text to fragment into separate boxes in one version, while acting as a single large text box in the other.
Before attempting heavy text edits directly in a PDF, check if you have access to the original source file (like Word or InDesign), as PDFs are final-format files and not designed for extensive text reflowing.
Edit the Original Source File
The most reliable way to avoid PDF text box fragmentation is to update the original document and export a new PDF.
PDF files are designed to preserve visual layouts for printing and sharing, not to replace original editable documents. Because Acrobat has to reverse-engineer the text layout, different versions (like XI vs. DC) use different algorithms.
Acrobat DC has improved paragraph recognition, often grouping text into a single box, while older versions like Acrobat XI might fragment text line-by-line based on exact coordinates.
Find the original file (.docx, .pptx, .indd, etc.) that was used to generate the PDF.
Open the file in its native application and apply all necessary text edits, layout adjustments, or formatting changes.
Navigate to "File" > "Save As" or "Export" and select the PDF format to generate a fresh, cleanly formatted version of your document.

Use PDF Editing Tools Manually
If the source file is unavailable, use your version's editing tools while adapting to its text box behavior.

Frequently Asked Questions
Can I merge separate text boxes in a PDF editor?
Most PDF editors do not have a one-click 'merge text boxes' feature. If text is heavily fragmented, the best workaround is to copy the text from the separate boxes, delete those boxes, insert a single new text box using the 'Add Text' tool, and paste the combined text inside.
Why are PDFs not ideal for heavy text editing?
The PDF format was invented to preserve exact visual layouts and ensure print fidelity across different devices, not to maintain logical text flow. Text is often stored as individual characters with specific page coordinates, forcing editors to guess how they group together into paragraphs.
How can I fix uneditable or broken text boxes in my PDF?
If text boxes are broken or unmanageable, you can convert the PDF into a Word document using a PDF-to-Word converter. This process reconstructs the document into standard, easy-to-edit paragraphs. After editing in Word, you can simply save it as a PDF again.
