- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Modifying existing text content within a PDF document using text editing tools.
- Observed behavior
- Letters move out of place, spacing alters unpredictably, and words overlap while the user is typing.
Verify that the fonts used in the original PDF are installed on your current computer, as missing or non-embedded fonts are the primary cause of text formatting distortion during edits.
Recreate the PDF from the Original Source with Embedded Fonts
The most effective way to prevent text formatting and spacing issues is to generate a new PDF from the original source file, ensuring all fonts are fully embedded.
When Acrobat edits a PDF, it relies on the text encoding and character positioning created by the original software. If fonts are not embedded, Acrobat attempts to substitute them, which leads to shifting and overlapping text.
Open the original document in its native application, such as Microsoft Word or Adobe InDesign.
Navigate to the 'Save As' or 'Export' menu and select PDF as the output format. Click on the 'Options' or 'Preferences' button.
Ensure the setting to 'Embed all fonts' or 'Embed fonts used in the document' is checked.
Save the new PDF file and open it in Acrobat Pro to perform your text edits smoothly.

Switch to a Locally Installed System Font
If the original source file is unavailable, replacing the problematic text's font with a standard font installed on your system can stabilize spacing and prevent overlapping.
Edit the Source Document Instead
For complex or scanned PDFs requiring major modifications, it is highly recommended to edit the original source document.
Edit PDF Text Seamlessly with WPS PDF
Avoid text overlapping and unpredictable spacing changes by using WPS Office to edit your PDFs. WPS PDF intelligently handles character positioning, preserves formatting, and allows you to edit PDF text as easily as a standard Word processor.
- 1. Download WPS Office: Download and install the free WPS Office suite on your computer.
- 2. Open Your PDF: Launch WPS Office and open your problematic PDF document.
- 3. Enter Edit Mode: Navigate to the 'Edit' tab at the top and click on the 'Edit Text' button.
- 4. Modify Text Smoothly: Click inside the text box and begin typing. WPS PDF will automatically adjust the layout to prevent any letter overlapping.

Frequently Asked Questions
Why do letters overlap when I type in an existing PDF?
This typically occurs when the font used to create the original PDF is not installed on your computer, or if the PDF was generated with absolute character positioning instead of standard text flows. The PDF editor struggles to calculate the correct width for the missing font.
How can I check if a PDF has embedded fonts?
Open the PDF document, go to Document Properties (File > Properties or Ctrl+D), and click on the 'Fonts' tab. This menu lists all the fonts used in the document and explicitly indicates whether they are embedded or not.
Is it better to edit the PDF or the source file?
It is always better to edit the original source file (like a Word or InDesign document) for major structural or text changes. PDFs are primarily an output format, and extensive text edits within a PDF often lead to formatting instability.
