How can I fix scrambled text or duplicated content when opening my PDF in UPDF on Mac?

To resolve this issue, go to UPDF > Settings > Documents, and disable the High Performance Mode. This should fix the problem.

To resolve this issue, go to UPDF > Settings > Documents, and disable the System Printing Mode. This should fix the problem.
Why does the text I type in UPDF suddenly appear vertically (one character per line) when editing a PDF, even though this didn't happen before?

This issue occurred due to a recent update where we made text alignment settings persistent. To resolve this and prevent the problem from happening again, simply follow these steps to set the text alignment to "Left Align":
- In editing mode, select the text that appears vertically in the text box.
- Choose the "Left Align" option.
Once you apply these settings, they will be saved as your preferred alignment, and you won't need to adjust it again in the future.
Why can I edit a PDF on other devices or software but not in UPDF?

This is likely because the PDF is protected from editing. To check, right-click the file, select "Properties," and go to the "Security" tab to view the document's permissions.
UPDF follows strict security guidelines and does not allow editing on protected documents to ensure the safety of your content. This is in line with other PDF editors, such as Adobe. While some software or devices may bypass these restrictions differently, the document is still password-protected and can't be edited in UPDF unless the restrictions are removed.
Why can't I install the OCR plugin on Windows?

The issue may be due to insufficient disk space on the drive where you're saving the OCR plugin. Ensure that the drive has at least 2GB of free space, then try reinstalling the plugin.
Why is the OCR feature in UPDF not working on Windows, and why do all scanned documents show the same result?

Please uninstall and reinstall the OCR plugin, then try again. This should resolve the issue. If the problem persists, kindly reach out to our customer service for further assistance.
How can I fix the issue if I can't install the OCR or UPDF Converter plugin on Mac?

If you're unable to install the OCR or UPDF Converter plugin, we recommend uninstalling and reinstalling UPDF. If the issue persists, please contact our customer service for further assistance.
Why did the form properties I customized in UPDF change when I opened the form in Preview?

This is an issue with Preview, as it does not support certain features. We recommend continuing to use UPDF for customizing, filling out, viewing, and signing forms to ensure all properties are preserved.
Why can't I edit the PDF?

This is likely because you're opening a scanned or image-based PDF. These types of PDFs can't be edited directly without OCR. To make the text editable, follow these steps:
- Click the OCR icon in the right panel.
- Select "Searchable PDF" as the document type, then choose the layout and document language.
- Click "Perform OCR."
UPDF will automatically process the file and open the OCR-processed version, which you can then edit in Edit mode.
Why does the OCR in UPDF seem different from Adobe's? I'm not happy with it.

UPDF works similarly to Adobe, and both provide highly accurate OCR results.
If you notice that the original format changes after performing OCR in UPDF, you can select the "Text over the page image" or "Text under the page image" layout option in the OCR settings. This will preserve the layout and formatting of your scanned document while performing OCR.
Why can’t I fill the PDF form using UPDF?

If you're unable to fill in a PDF form, please switch to "Prepare Form" mode. Then, enable "Form Field Recognition" and "Highlight Existing Fields." This will make the form fields visible, allowing you to fill them out easily.
