PDF Reader: common problems and how to fix them
Resolve search finds no word in a scan and the outline panel is empty. Understand the limits before retrying.
Open PDF Reader →Follow these steps
- Choose your PDF. On a phone, pages scroll continuously below the attached reading toolbar.
- Use the page-number field to jump, the zoom control to fit the page width, or Search and reading options for text search, the outline and bookmarks. The + button adds PDF files.
- Read without exporting. On desktop, the existing reading views and download controls remain available. View rotation does not change the PDF.
Search finds no word in a scan
A photographed page has no text layer to search. Make a searchable copy with OCR first, then verify recognition against the visible page.
The outline panel is empty
The PDF may not contain bookmarks. Use page navigation or search; printed chapter titles alone do not create reader outline entries.
Check whether this is the right operation
Reader zoom and viewing layout affect the screen, not the original file. Two-page viewing is useful on a wide screen; continuous single-column reading usually makes better use of a phone.
A more useful retry
For a long manual, navigate with its outline rather than scrolling through every page. Search a distinctive phrase to find a section, then read the surrounding paragraph; a match alone may lack the context needed to interpret it.
Check the result
View rotation and zoom do not alter document bytes. Extracted text can have an incorrect reading order in untagged documents. The Reader prompts for a password for protected files. Reading retains the encrypted source; use Remove password explicitly before editing.
Keep the original. When this task produces a file, reopen the download in the application where you will use it and inspect the affected pages. An illustration explains the operation; it is not a recorded processing test.
Practical tips
- Choose the viewing mode before adjusting zoom. Search real text and use page positions for navigation. Keep page orientation changes in the reader separate from exported Rotate changes.
- A photographed page has no text layer to search. Make a searchable copy with OCR first, then verify recognition against the visible page.
