Deleting pages from a PDF is useful when you want to remove blank pages, unnecessary cover pages, confidentiality pages, or sections that should not be shared. OnlinePdfEditor displays thumbnails of all pages and lets you select the ones to remove before exporting the reduced document.
The interface is designed for clarity: you see all pages as thumbnails, select the ones to delete with a click (highlighted in red), and the resulting document excludes those selected while preserving all others in the original order. You can also enter page numbers to delete directly via text field using the same range syntax as other tools (e.g. '1,3,7-10').
Difference from similar tools: 'Delete Pages' is the inverse operation of 'Extract Pages' — instead of specifying which pages you want in the result, you specify which ones to exclude. It is more convenient when the document has many pages and you want to keep most of them, removing only a few. 'Organize PDF' does the same thing but also adds the ability to reorder remaining pages via drag-and-drop. If you do not need reordering, 'Delete Pages' is faster.
