删除页面

Upload the file, then either type the pages in the box using ranges like 2, 4-6, 9 or click the page thumbnails to mark them. Marked pages are highlighted so you can double-check before clicking the button, and the result downloads as a new PDF with those pages gone.

No. At least one page has to remain, and the tool refuses with an error if your selection covers the whole document.

No. The kept pages are copied over unchanged, including their text, images, fonts, and order, so nothing is re-rendered or recompressed.

Links and annotations that live on the kept pages come along, but the document's bookmark tree isn't carried over because the pages are copied into a fresh PDF. If you need bookmarks afterward, rebuild them with Edit Bookmarks.

You'll be prompted for the password when you upload the file. The downloaded PDF is saved without the password, so add protection again with Protect PDF if the document still needs it.

Usually, if the removed pages carried their own images or fonts, since only the resources the kept pages reference are written to the new file. Pages that share resources with the rest of the document free up less space.

No. The thumbnails are rendered and the new file is assembled in your browser, so the document stays on your device from upload to download.

Use Extract Pages, which does the reverse: you list the pages to keep and everything else is left out. The output is the same kind of clean copy.
