Fix Cannot Resize or Move Text and Signatures in Acrobat Reader
Question details
The user is unable to resize or move text boxes, signatures, or initials using the mouse drag feature in Acrobat Reader, forcing reliance on keyboard arrows and font buttons.

- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Attempting to adjust the size and position of text fields, initials, or signatures while filling out or editing a PDF document.
- Observed behavior
- Dragging the edges of a text box or signature no longer resizes or moves the object; users are forced to use the arrow keys to move items or the 'A A' floating buttons to resize text.
Verify if the issue occurs across multiple PDF files or just one, as specific document security settings can restrict editing and signing behaviors.
Verify Editing Tools and Reset Acrobat Preferences
Ensure the correct selection tool is active, check document security restrictions, and reset application preferences to restore default drag-and-drop functionality.
Often, basic editing functions fail to respond if the software is stuck in a different viewing mode, or if temporary cache issues interrupt normal mouse behaviors in Adobe Acrobat.
Make sure you are actively using the 'Fill & Sign' or 'Edit PDF' tool from the right-hand pane, rather than the standard Hand or Select tool, to modify added elements.
Go to File > Properties and click the Security tab to ensure the document permissions allow for 'Filling of form fields' and 'Signing'.
Navigate to Edit > Preferences (Windows) or Acrobat > Preferences (Mac), note your custom settings, and reset the application preferences to clear out software glitches affecting mouse inputs.
Close Adobe Acrobat Reader completely, reopen it, load your PDF, and try clicking and dragging the edge of a text box again.

Check Mouse and Touch Workspace Settings
Conflicts with mouse drivers or touch workspace modes can prevent the drag-to-resize action from registering correctly.
Easily Add, Move, and Resize Text in PDFs with WPS Office
If Acrobat Reader continues to restrict your editing capabilities or glitch during simple tasks, WPS Office provides a powerful, lightweight PDF editor. You can seamlessly add text, insert signatures, and freely drag to resize or position elements anywhere on your document without arbitrary restrictions.
- 1. Open your PDF: Launch WPS Office and open your target PDF document from the home screen.
- 2. Add Text or Signature: Navigate to the 'Edit' tab and click on 'Edit Text' or 'Insert Signature' from the top ribbon.
- 3. Resize and Move freely: Click once on the text box or signature to reveal the blue bounding box, then drag the corner handles to resize, or click and drag the center to move it anywhere on the page.

Frequently Asked Questions
Why can't I edit a specific PDF document in Acrobat Reader?
The creator of the document may have applied security restrictions. You can check this by going to File > Properties > Security. If editing is restricted, you will need the original permissions password to modify text or signatures.
Is there a keyboard shortcut to resize text if my mouse drag isn't working?
While Acrobat doesn't have a direct drag-resize shortcut, you can select the text box and use the floating 'A A' toolbar that appears above it to incrementally increase or decrease the font size.
Why did my text box turn into a generic view when trying to move it?
This often happens if the 'Hand Tool' or standard view cursor is active instead of the specific editing selection tool. Ensure you have activated the 'Fill & Sign' or 'Edit' function from the right panel before attempting to modify objects.
