Fix PDF Characters Disappearing After Creation in Adobe Acrobat
Question details
Characters are missing or disappear after converting a document to PDF in Adobe Acrobat, even when fonts are seemingly embedded.
- Product
- Adobe Acrobat
- Device & OS
- Windows
- Scenario
- Creating a PDF from a source application or scanning a document to PDF.
- Observed behavior
- Specific text characters disappear from the final PDF output despite using standard fonts like Century Gothic.
Before troubleshooting, ensure that you have the original source document and note the exact font (e.g., Century Gothic) that is failing to render.
Isolate the Source Application and Test Font Embedding
Determine if the issue is tied to a specific font, the original source software, or the scanning process to apply the correct fix.
Disappearing characters during PDF creation are typically caused by font licensing restrictions, OCR failures during scanning, or outdated software. By isolating the conversion method, you can identify the exact point of failure.
Open the original document in its native app (e.g., Microsoft Word) to verify no text is missing or corrupted before the PDF conversion process begins.
Change a section of the document's font from the problematic one (like Century Gothic) to a standard system font such as Arial or Times New Roman, then recreate the PDF to see if the characters appear.
If the PDF was created via a scanner, check your OCR (Optical Character Recognition) settings in Acrobat. Go to 'Tools' > 'Scan & OCR' > 'Recognize Text' to ensure the text is being processed properly.
Go to 'Help' > 'Check for Updates' in Adobe Acrobat to ensure you have the latest software patches, which frequently resolve font rendering bugs on Windows.
Create Flawless PDFs with WPS Office
If your current PDF creator continues to drop characters, use WPS Office's built-in PDF converter. It ensures 100% font retention and accurate document formatting without complicated settings.
- 1. Open your document: Launch WPS Office and open the original source file (Word, Excel, or PowerPoint) you want to convert.
- 2. Access the Export feature: Click on 'Menu' in the top-left corner and select 'Export to PDF' from the dropdown list.
- 3. Configure and Export: In the export dialog box, verify your desired page range and export path, then click the 'Export to PDF' button.
- 4. Verify the output: Open the newly created PDF in WPS PDF to verify that all characters, fonts, and formatting are perfectly retained.
Frequently Asked Questions
Why do some fonts disappear when converting to PDF?
This usually happens if the font has restricted licensing that prevents embedding, or if the PDF converter fails to substitute an unavailable font properly during the creation process.
How do I force embed fonts in Adobe Acrobat?
Go to Edit > Preflight, select 'PDF fixups', and choose 'Embed fonts'. Alternatively, ensure 'Embed all fonts' is checked in your Adobe PDF Printer settings under the Job Options tab.
Can scanning cause characters to disappear in PDFs?
Yes. If the scanner's resolution is too low or the original text is faded, the OCR (Optical Character Recognition) engine may fail to recognize certain characters, resulting in missing or invisible text in the searchable PDF layer.
