- Device & OS
- not provided
- Scenario
- Opening a PDF document to read or review its contents.
- Observed behavior
- The PDF text displays as dots, squares, or unreadable characters in older versions of Adobe Reader, while displaying correctly in newer releases.
Check if the issue happens with all PDF files or just one specific document, and ensure you have an active internet connection to download software updates.
Update Adobe Reader to the Latest Version
Outdated software often lacks the rendering engines needed for modern fonts. Updating to the latest version usually resolves text display issues.
Older versions of PDF readers may struggle to interpret modern font embedding methods or newly developed document formats, leading to visual glitches like dots or blank spaces.
Launch your current version of Adobe Reader or Acrobat and navigate to the 'Help' menu located at the top toolbar.
Click on 'Check for Updates' from the dropdown list. The application will connect to the server to look for the newest available version.
Follow the on-screen prompts to download and install the latest version supported by your operating system.
Restart the application after installation is complete, then open the problematic PDF file again to ensure the text renders correctly.
Embed Fonts When Creating the PDF
If you are the creator of the PDF, embedding fonts ensures the file displays correctly on any device or reader, regardless of locally installed fonts.

Frequently Asked Questions
Why do PDFs sometimes show dots instead of text?
This usually happens when the PDF reader is too old to interpret the embedded fonts or modern rendering instructions in the PDF file, or when the necessary fonts were not properly embedded during the file's creation.
Can missing system fonts cause unreadable characters in PDFs?
Yes. If a font used in the document is not installed on your computer and was not embedded within the PDF itself, the software may substitute it incorrectly, resulting in dots, squares, or wingding characters.
How do I know if my fonts are successfully embedded in a PDF?
In most standard PDF readers, you can go to File > Properties and look for the 'Fonts' tab. If the fonts say '(Embedded)' or '(Embedded Subset)' next to their names, they have been successfully packaged within the file.
Will changing my PDF viewer fix the dot problem without updating?
Often, yes. Using a modern alternative PDF reader like WPS PDF can immediately bypass the rendering bugs or font-handling limitations present in your outdated software, allowing you to read the document normally.
