Frequently Asked Questions

Why can't I select or edit the text in my PDF file?

If your PDF is created from a scanned document or an image, the text is not selectable or editable by default. You will need to use a PDF editor with OCR (Optical Character Recognition) to convert the image into editable text before you can format it.

Can I format text using Google Chrome's default PDF viewer?

No, the default PDF viewer in Google Chrome only supports viewing documents and basic form filling. To edit existing text and apply formatting like bold or underline, you must use a dedicated PDF editor.

How do I remove the bold or underline format from PDF text?

To remove the formatting, enter the 'Edit Text' mode in your PDF editor, highlight the affected text, and click the active Bold or Underline icon on your toolbar to toggle the formatting off.
