What is the Remove Pages tool?
Feed it a PDF, tick off the pages you have no use for, and it hands back the same document minus those pages. That is the whole job. It is the quickest way to delete pages from PDF online when a file arrives with a fax cover sheet, a duplicate scan or six empty sheets at the end.
Scanners are the usual culprit. Duplex scanning a one-sided stack gives you a blank page after every real one. A colleague sends a 40-page report when you only need the summary and the invoice. Someone leaves the lid up and page 12 is a grey rectangle. Rather than reprinting or re-scanning, remove the offending pages and keep everything else exactly as it was.
The tool also knows how to spot empty pages by itself: tick the blank-page option and each page is rendered on your device and measured for ink, so almost-white pages get flagged for you. All of that rendering, measuring and rewriting happens inside your browser — the PDF is never uploaded, and the file you download is written locally by pdf-lib.
How to remove pages from a PDF online
- Drop your PDF on the box at the top of the page, or click it and pick the file.
- Type the pages to delete in the Pages to remove box — for example 2, 5-7 — or click the numbered buttons underneath to mark them one by one.
- Use Odd, Even, Invert or Clear when the pattern is regular, such as every second page of a duplex scan.
- Open Advanced options and tick “Also remove blank pages automatically” if you want empty scans found for you; drag the sensitivity slider until the count looks right.
- Look at the preview: doomed pages get a red cross and a “will be deleted” badge, survivors show their new page number, and the footer tells you how many pages the result will have.
- Press the Remove button — it names the exact number of pages going — and the trimmed PDF downloads as yourfile-pages-removed.pdf.
Key features
- Two ways to choose pages — a range box that accepts things like 1, 4-9 and a grid of numbered page buttons; both stay in sync.
- Automatic blank-page detection — each page is rendered and its ink coverage measured, so sheets that are effectively empty are marked for removal.
- Adjustable blank sensitivity — set the threshold anywhere from 0.05% to 3% ink, so a page with a faint scanner smudge or a stray staple mark can still count as blank.
- Odd, Even, Invert and Clear — one click handles duplex leftovers or flips your selection into “keep only these”.
- Preview that shows both sides of the decision — red crosses on the pages leaving, green “kept, page 3 of 18” labels on the ones staying, and the ink reading for the page you are on.
- Safety rail — the tool refuses to save a document with zero pages, so you cannot accidentally delete the lot.
- Untouched originals — your source file is never modified; you get a new PDF and the old one stays on disk.
Benefits of using this PDF page remover
- Confidential scans stay private. Payslips, medical letters and ID copies are processed in the browser, so nothing is sent to a server to be trimmed.
- Blank hunting stops being manual. Instead of paging through 200 scans looking for empties, you set a sensitivity and check the flagged pages.
- Kept pages are byte-copied. Surviving pages are copied into the new file rather than re-rendered, so text stays searchable and images keep their resolution.
- No account, no quota, no watermark. Delete two pages or two hundred, as often as you like, with nothing stamped on the output.
- Reversible by nature. Because a new file is written, a mistake costs you one download — the original is still there to try again.
Who should use this tool?
Students handing in coursework
Submission portals often cap page counts or forbid extra material. Strip the marking rubric, the blank separator sheets and the draft pages you no longer want assessed, then upload a document that contains only the work itself.
Admin and records staff
Filing a batch of duplex scans means half the pages are empty. Tick blank detection, glance at the flagged list, and save a file that is roughly half the size with none of the padding — much friendlier to the records system and to whoever prints it next.
Anyone trimming a scan before sharing
Bank statements and contracts often carry pages you would rather not circulate: terms you did not agree, an unrelated account summary, a page with a signature you do not want copied. Mark those pages, check the red crosses, and send the shortened copy instead.
Freelancers and small businesses
Templates arrive with instruction pages and internal notes at the front. Delete them before the document goes to a client, and use Invert when it is easier to select the handful of pages worth keeping and remove everything else.
Frequently asked questions
How do I remove pages from a PDF without Acrobat?
Open this page, load the file, mark the unwanted pages and save. It runs entirely in the browser, so there is nothing to install and no subscription involved.
How does the blank-page scanner decide a page is empty?
Each page is drawn on a small hidden canvas and the tool counts the pixels that are not near-white. If that share falls below the sensitivity you set, the page is treated as blank and marked for deletion.
Can I get rid of every second page from a duplex scan?
Yes — press Even (or Odd, depending on which side is empty) to mark the whole series at once, then spot-check a few in the preview before saving.
Should I use this or the Extract Pages tool?
Use this one when most of the document is worth keeping and a few pages must go. If you only want a small slice — one chapter out of a book, say — Extract Pages copies just those pages into a new file, which is less clicking than deleting all the rest.
Does deleting pages make the file smaller?
Usually, yes, because the content of removed pages is not copied into the new document. Shared resources such as embedded fonts may still be carried over, so run Compress PDF if you need a specific size.
Can I delete pages from a password-protected PDF?
Not while it is locked; the page will ask you to unlock it first. Remove the password with Unlock PDF and then delete pages from the unlocked copy.
Do bookmarks and form fields survive?
Page content, images and form fields on the kept pages are copied across. Document-level extras such as the bookmark outline are not rebuilt, so a long file may lose its outline panel — worth checking if you rely on it.
What happens if I mark every page?
Nothing gets saved. The tool tells you to keep at least one page, because a PDF with no pages is not a valid document.
