Practical use cases
- Removing a blank cover sheet or a stray scanned page that a scanner or printer added by mistake.
- Cutting a terms-and-conditions page or an internal cover page out of a document before sending it externally.
- Trimming a long report down to just the sections you need, by removing everything else rather than rebuilding the file from scratch.
What happens to the pages you remove
Delete works by keeping a list of every page number in the document, removing the ones you selected, and copying the rest — in their original order — into a brand-new PDF. Nothing about the kept pages is altered: no resizing, no re-rendering, no change to their content. A built-in safeguard stops you from deleting every page in one action, since the tool always needs at least one page left to build the resulting file.
Common problems
- Clicking Delete doesn't seem to do anything: check that at least one thumbnail is actually marked — "Select at least one page to delete" means none are yet.
- You tried to remove everything: "You cannot delete all pages" appears — deselect at least one page you want to keep.
- Thinking in terms of "which pages to keep" instead of "which to remove"? That's exactly what Extract does — same result, opposite selection.
