How to Fix Garbled Text When Editing PDFs in Acrobat Pro DC
Question details
The user experiences garbled text and unusual fonts when activating the Edit PDF tool on a specific document.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Attempting to edit a business card PDF using a seven-day trial of Acrobat Pro DC.
- Observed behavior
- The PDF displays perfectly in normal view mode, but the text instantly becomes garbled and fonts change to unusual characters as soon as the Edit PDF function is enabled.
Before attempting to edit, save a backup copy of your original PDF file. Verify if the PDF was created from a scanned image, as this often requires optical text recognition before editing.
Run OCR on the Scanned PDF Document
If the document is a scanned image or lacks proper font encoding, running Optical Character Recognition (OCR) converts the image layer into editable text.
Garbled text frequently occurs when Acrobat tries to edit a document that doesn't have a clean text layer, such as a scanned business card. Running OCR builds a new, readable text layer.
In Acrobat Pro DC, navigate to the 'Tools' menu and select the 'Scan & OCR' option.
Click on 'Recognize Text' in the toolbar and select 'In this File'. Apply the necessary language and output settings, then click 'Recognize Text' to convert the document.
Once the OCR process is complete, return to the 'Edit PDF' tool and check if the text now displays and edits correctly.
Verify and Embed Missing Fonts
Garbled text can appear if the original fonts used in the document are not installed on your system or weren't embedded properly during creation.
Use WPS PDF to Edit Documents Without Formatting Loss
If you consistently encounter encoding issues or garbled text in other PDF editors, try WPS Office. WPS PDF offers advanced text recognition, smooth editing, and robust font compatibility to ensure your documents retain their original formatting.
- 1. Open the PDF in WPS Office: Launch WPS Office and open your problematic PDF document.
- 2. Select the Edit Tool: Navigate to the 'Edit' tab on the top ribbon and click on the 'Edit Content' or 'Edit Text' button.
- 3. Modify Your Text: Click directly on the text block you wish to modify. WPS PDF will automatically analyze the encoding and match the existing font.
- 4. Save Your Changes: Once editing is complete, click the 'Save' icon or press Ctrl+S to preserve your updated PDF without any garbled text.
Frequently Asked Questions
Why does my PDF look fine when viewing but gets garbled when I try to edit it?
This happens when the PDF contains damaged text encoding or relies on embedded fonts that are missing from your computer. The PDF viewer uses the embedded outline data to display the document correctly, but the editor requires the actual system font to make changes. Without it, the text mapping breaks down.
What is a scanned PDF, and why does it cause editing issues?
A scanned PDF is essentially a flat image of a document rather than a file with distinct text characters. When you try to edit it directly, the software struggles to map the image to real text characters, resulting in garbled text. You must run Optical Character Recognition (OCR) first to create editable text.
How do I ensure fonts are embedded when saving a PDF?
When creating or exporting a PDF from original software like Microsoft Word or Adobe Illustrator, check the advanced export settings or preferences. Ensure that options like 'Embed all fonts' or 'PDF/A compliance' are checked before saving.
Can I fix text encoding issues without recreating the PDF?
Sometimes. You can try the 'Print to PDF' method to create a new, flattened file, and then run an OCR scan on this newly printed document. This bypasses the corrupted font encoding by treating the file as an image and generating a fresh layer of editable text.
