Question details
The user experiences words or characters disappearing when a PDF file is saved and reopened.
- Product
- Device & OS
- not provided
- Scenario
- Saving and then reopening a PDF document.
- Observed behavior
- Text, words, or specific characters vanish or fail to render properly upon reopening the saved PDF, typically due to font embedding or export issues.
Ensure you have access to the original source document (such as a Word document or PowerPoint presentation), as you may need to re-export the PDF with corrected font settings.
Re-export the PDF with Font Embedding Enabled
The most common cause of disappearing text is missing fonts. Re-exporting the source document while ensuring fonts are embedded resolves this issue.
When a PDF is created, it references the fonts used in the original document. If those fonts aren't embedded into the PDF file and the device opening the PDF doesn't have them installed, the text may disappear or display incorrectly.
Open the original source file (e.g., in WPS Writer or Microsoft Word) that was used to create the PDF.
Navigate to the 'File' menu and select 'Export to PDF' or choose 'Save As' and select PDF as the format.
Click on 'Options' or 'Advanced Settings' in the export dialog box, and check the box labeled 'Embed fonts in the file' (or similar wording depending on your software).
Click 'OK' and save the new PDF file. Open the newly exported PDF to verify that the text remains intact after saving.
Change the Source Document to Standard Fonts
If custom or unsupported fonts are causing rendering issues, switching to standard web-safe fonts can fix the problem.
Test the File in a Different PDF Viewer
Sometimes the problem is localized to a specific PDF reader's rendering engine rather than the file itself.
Use WPS Office to Export and View PDFs Without Text Loss
WPS Office provides a highly compatible PDF editor and viewer. Its robust export features ensure all fonts are properly embedded, preventing missing text issues when saving and sharing your documents.
- 1. Download WPS Office: Download and install the free WPS Office suite on your device.
- 2. Open your source file: Open your original document (Word, Excel, or PowerPoint) directly in WPS Office.
- 3. Export to PDF: Click 'Menu', select 'Export to PDF', and ensure the advanced settings are configured to embed fonts.
- 4. View the result: Open the resulting PDF in WPS PDF to verify all text is securely saved.
Frequently Asked Questions
Why do certain characters disappear but others stay in my PDF?
This usually happens if you used a special font for certain characters or symbols, and that specific font wasn't embedded in the PDF. Standard text renders using default system fonts, but custom characters will vanish if the viewer cannot find the exact font data.
Can I fix the missing text directly within the saved PDF?
If the text data was lost during the saving process due to export errors, you generally cannot recover it from the PDF itself. The best method is to go back to the original source file, enable font embedding, and create a new PDF.
How do I check if fonts are embedded in my PDF?
You can check font properties in most standard PDF readers. Open the PDF, go to 'File' > 'Properties' (or 'Document Properties'), and click the 'Fonts' tab. This will list all the fonts used in the document and indicate whether they are embedded or embedded as a subset.
