Delete PDF pages: remove pages and blank sheets
To delete pages from a PDF, click the thumbnails of the pages to remove or type the numbers, such as 2, 5-7. The file is rewritten without them, and their text and photos leave the file, not just the page list. Blank pages are found by ink: at most 0,1% dark dots.
The PDF never leaves your device
