Frequently Asked Questions

Why does a PDF look perfectly fine on my computer but garbled on my phone?

Desktop PDF viewers usually have access to a massive library of system fonts. If a PDF is created without embedding its custom fonts, a mobile app will attempt to substitute those missing fonts with the few it has available, often resulting in garbled or overlapping text.

What does it mean to 'flatten' a PDF document?

Flattening a PDF means combining all of its separate elements—such as text layers, images, form fields, and annotations—into a single, uneditable background layer. This simplifies the file's code, making it much easier for mobile apps to render correctly.

How do I embed fonts when creating a new PDF?

Fonts are embedded during the export or save process in the software you used to create the document (like Microsoft Word or Adobe InDesign). You usually need to go to 'Options' or 'Advanced Settings' in the Save As PDF dialog box and check the box labeled 'Embed fonts in the file'.

Can repairing the PDF file fix garbled text?

Sometimes. If the text is garbled because the file became slightly corrupted during download or transfer, using a free online PDF repair tool or simply redownloading the file from the original source can fix the issue.
