How to Prevent Adobe Acrobat From Selecting Text With a Box
Question details
The user wants to select and highlight text normally without the PDF reader drawing a bounding box or automatically switching to an editing mode.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to select, highlight, or copy specific lines of text within a PDF document.
- Observed behavior
- The software creates a selection box or automatically jumps into Edit PDF mode instead of smoothly highlighting the text.
Ensure that your PDF is a standard text-based document rather than a scanned image, as normal text selection tools cannot highlight text within flattened images without OCR.
Adjust Selection Preferences and Tool Settings
Switching to the correct tool and disabling the preference that prioritizes images over text will resolve most box-selection issues.
Acrobat sometimes defaults to selecting block elements or entering form-editing modes when you click on the document. Ensuring the basic Select tool is active and adjusting the General preferences stops this behavior.
Ensure you are not actively using the 'Edit PDF' or 'Prepare Form' tools, as these prioritize object and field selection. Switch back to the standard 'Select' or 'Hand' tool.
Navigate to the top menu bar, click on 'Edit', and select 'Preferences' from the drop-down menu.
In the Preferences window, select the 'General' category from the left-hand panel.
Under the 'Basic Tools' section, uncheck the box labeled 'Make Select Tool select images before text'.
Click the 'OK' button at the bottom of the window to save your settings, then try selecting your text again.

Change Page Properties to Use Document Structure
If the document contains overlapping elements, forcing the PDF to use the underlying document structure can help the Select tool recognize text properly.
Use Multi-Click Methods and Keyboard Shortcuts
Instead of clicking and dragging your mouse, which may trigger a box selection, use targeted clicks and keyboard modifiers.
Select and Edit PDF Text Effortlessly With WPS Office
If you frequently struggle with complicated selection modes and unexpected bounding boxes, WPS Office provides an intuitive PDF reader and editor that lets you highlight, copy, and modify text seamlessly.
- 1. Open your PDF: Launch WPS Office and open your target PDF document.
- 2. Choose the Select Tool: Click the 'Select' pointer tool located on the top navigation ribbon.
- 3. Highlight text smoothly: Click and drag your cursor over the desired text. The tool will automatically snap to the text lines without drawing a bounding box.
- 4. Copy or Edit: Right-click the highlighted text to copy it, or switch to the 'Edit' tab to directly modify the document's contents.

Frequently Asked Questions
Why does my PDF select as one large block instead of individual words?
This usually occurs if the PDF was saved as a flat image, exported from a scanner without OCR, or if your PDF reader's selection tool is prioritizing objects over text. Disabling the 'select images before text' preference often resolves the issue for standard PDFs.
Can I select text in a scanned PDF document?
Not directly with standard selection tools. A scanned PDF is essentially a photograph of text. You must first use an OCR (Optical Character Recognition) tool to analyze the image and convert it into selectable, searchable text.
What is the difference between the Hand tool and the Select tool?
The Hand tool is designed to grab the page and pan around the document for easier reading and navigation. The Select tool is specifically engineered to interact with the document's contents, allowing you to highlight text or select specific images for copying.
