Quick answer
- Remove Pages deletes the pages you pick and saves a new PDF with the rest, right in your browser.
- The file only gets smaller if those pages held images or fonts no other page uses. Shared resources can stay in the file.
- Deleting a page from a signed PDF breaks the signature, because a digital signature locks the exact bytes of the file.
- Want the removed pages too, not just the ones left behind? Use Extract Pages instead.
How do I remove pages from a PDF?
Remove Pages opens your file, lets you pick pages by clicking their thumbnails or typing page numbers, and saves a new PDF with just the rest.
- Pick pages fast: type something like "3, 7-9" to mark several pages at once instead of clicking each one.
- One page has to stay: a PDF can't be empty, so at least one page must remain in the file.
- Works on a phone: Remove Pages runs in the browser, no app or printer needed.
- Your original stays put: the tool writes a new file, so the source PDF is untouched unless you overwrite it yourself.
Will removing a page make the file smaller?
Sometimes. The file shrinks by roughly what that page's own content weighed, but pages that share a font or image with the rest of the file won't free up that space.
- Shared resources stay: if page 2 and page 5 use the same photo, deleting page 2 keeps the photo, because page 5 still needs it.
- Images make the difference: cutting a few full-page scans trims far more than removing several pages of plain text.
- Still too big? Run what's left through Compress PDF to squeeze the images that remain.
Does removing a page break a digital signature?
Yes, in almost every case. A digital signature locks the exact bytes of a signed PDF, so deleting, adding or reordering even one page invalidates it.
- Any change counts: a signature breaks the moment a single byte changes, not only when the visible text changes.
- Go back to the source: if you need different pages, edit the unsigned original with Remove Pages, then have it signed again.
- More than one signer: removing a page after the first signature invalidates that signature too, even if later ones came after it.
What's the difference between removing and extracting pages?
Remove Pages deletes pages from the file you already have. Extract Pages copies the pages you pick into a new file and can leave the original untouched.
- Remove when the pages you picked are the ones you don't want: Remove Pages drops them and keeps the rest.
- Extract when the pages you picked are the ones you want to keep on their own: Extract Pages pulls just those out.
- A full split is different again: it cuts one file into several smaller ones instead of picking out individual pages.
Can I remove pages from a password protected PDF?
Only if you have permission to edit it. Some PDFs block page removal with an owner password even though they open without one.
- Two different passwords: an open password stops the file opening at all, while a permissions password just limits editing or page removal.
- A separate editing flag: PDF security settings can allow printing while still blocking anyone from inserting, deleting or rotating pages.
- Unlock it first: for a file that's yours to edit, Unlock PDF clears the password so Remove Pages can change it.

Common questions
Can I remove pages from a PDF on my phone?
Yes. Remove Pages runs in your phone's browser, so you pick the pages and save the new file without installing an app.
What happens to bookmarks that pointed at a removed page?
They disappear along with the page. Bookmarks pointing further into the file still work, just shifted to match the new page numbers.
Can I remove pages from a scanned PDF the same way?
Yes. A scanned page is still just a page, image and all, so Remove Pages deletes it the same way it deletes a text page.
Can I undo removing a page from a PDF?
Not inside the saved file. Removing pages writes a new PDF, so keep your original until you're sure you won't need those pages again.
