Remove PDF Pages Online

1. 1

   Open your PDF

   Drop the file onto the page or browse for it. Every page appears as a thumbnail — not just the first thirty.

2. 2

   Pick the pages to delete

   Click any thumbnail to mark it, or type a range such as 1-3,7,10-15. Odd, even, blank and duplicate pages can each be selected in one press.

3. 3

   Check what will remain

   The rail states how many pages will be deleted, how many will remain, and exactly which numbers are going, before anything happens.

4. 4

   Remove and download

   Press the button, review the finished document in the preview, and download it under whatever name you like.

A PDF almost never arrives containing exactly what you want to send on. A scan carries the blank backing sheet behind every double-sided page. A report has a cover, a disclaimer and eight pages of appendix that nobody asked for. A contract downloaded from a portal comes with the portal's own header page in front of it. Removing pages turns a document you were given into the document you actually need, without asking the sender for another copy and without rebuilding it by hand.

Benefits of Page Removal

• Send only what matters: a five-page extract from a sixty-page report reads as considered rather than lazy.
• Smaller files: every page you delete takes its images and fonts with it, so a scan often halves once its blank sheets are gone.
• Cleaner scans: duplex scanning produces an empty sheet for every single-sided original, and they are tedious to find by eye.
• Fewer mistakes: removing an obsolete page is safer than trusting the reader to skip it.
• Nothing re-encoded: the pages that survive are copied exactly, so a signed or scanned document keeps its fidelity.

There are two honest ways to name a page, and this tool offers both because people genuinely think in both. Some documents you know by sight — you can see the cover page and the two duplicated invoices, and clicking them is faster than working out their numbers. Others you know by structure: the appendix is pages 40 to 60, the odd pages are the fronts, the range came out of an email. Clicking and typing address the same selection, so you can start with one and finish with the other.

Every Way to Select a Page

• Click a thumbnail: toggles that one page. Click it again to change your mind.
• A range: 1-3,7,10-15 in the range box. Spaces, semicolons and en-dashes all work, and anything the document cannot satisfy is named rather than ignored.
• Odd or even: one press marks every front or every back of a duplex scan.
• Blank: every page under the ink threshold, once the document has been measured.
• Duplicates: every page that repeats an earlier one, first copies excluded.
• Invert and clear: turn a short selection into its complement, or start again.

A filter chooses a set; the Select and Deselect buttons decide what happens to it. That separation is what lets you combine filters — select all the blank pages, then deselect page 12 because it is a deliberate separator you want to keep.

This is the part of the job every other page remover leaves to you. Deleting pages you can already see is easy; the work is finding the twelve blank sheets and the three pages the feeder pulled twice out of a ninety-page scan. Pressing Find blank and duplicate pages measures every page once and badges what it finds, and both answers then become selectable filters.

How Blank Detection Works

Each page is rendered and measured for the proportion of it that is darker than paper. A genuinely empty page measures zero. A page carrying nothing but a footer measures a fraction of one percent. The threshold is a slider rather than a fixed number, because how blank a page has to be before you want it gone is a judgement about your document, not a property of the file — a scan with speckle from the glass needs a little tolerance, a generated report needs none. Move the slider and the badges update immediately; no page is re-measured.

How Duplicate Detection Works

Every page is reduced to a small map of how light and dark it is across its surface, and each page is compared against the ones before it. Pages that match closely, and have the same shape, are grouped. Only the repeats are ever selected — the first copy of anything is left alone, so removing duplicates can never leave you with none of a page you meant to keep one of. Blank pages are deliberately excluded from the comparison: every empty page resembles every other empty page, and treating them as duplicates would quietly delete all but one of your separator sheets when you asked about content.

Sometimes the pages you want are easier to name than the pages you do not. Extracting the four pages of a contract that actually need signing from a forty-page pack is a keep, not a remove, and inverting that selection by hand is exactly the sort of tedious arithmetic that produces an off-by-one. Switching the mode reads the same selection the other way round: in Keep selected, the pages you have picked survive and everything else goes. The grid strikes through whatever is leaving in either mode, so what you are about to do is always the thing shown on screen.

Which Mode to Use

• Remove selected: when the unwanted pages are the shorter list — a cover, a few blanks, an appendix.
• Keep selected: when the wanted pages are the shorter list — an extract, a chapter, the pages that need signing.

A PDF is a tree of objects with a page list at its root. Removing a page does not erase anything from that tree directly — it builds a new document containing only the pages you kept, copying each one's content stream, fonts and images across untouched. That is why the result is lossless: nothing is decoded and re-encoded on the way through, so a scanned page comes out with exactly the pixels it went in with, and a vector chart stays vector. It is also why the file usually shrinks by more than you expect, since everything only the deleted pages referred to is left behind.

What Happens When You Press Remove

• Read: the document's page list, page sizes and rotations are read without decoding a single image.
• Resolve: your selection and the current mode are turned into one list of pages to drop and one list to keep.
• Copy: the surviving pages are copied into a new document in batches, so the page keeps responding while it happens.
• Save: the new document is serialised and handed back as a file, with the original's title, author and dates intact.
• Preview: the finished document is displayed so you can check it before saving it anywhere.

Pages are copied rather than re-encoded, so a removal costs a single pass over the document.

The promise this tool makes is narrow and worth stating exactly: the pages that survive are unchanged. It is a promise that is easy to break by accident, and most of it is invisible when it is broken — a page-removal tool that silently re-encodes images, or that stamps its own name over the document's author field, produces a file that looks perfect and has quietly lost things a document management system indexes on.

Field by Field

• Unchanged: page content, images, fonts, vector graphics, page size, page rotation, and the document's title, author, subject, keywords and creation date.
• Changed: the page count, the page numbering that follows from it, and the file size.
• Not carried: bookmarks, links and form fields that pointed at a page you deleted have nothing left to point at.
• Never re-encoded: no image is decompressed and re-compressed, so nothing loses fidelity in transit.

Twenty invoices from the same system have their cover page in the same place. With Pro, all of them can be opened together, and the selection made on one document can be copied onto every other in a single press — pages a shorter document does not have are simply dropped rather than carried onto the wrong page. Each document keeps its own selection afterwards, so an exception is still one click, and everything finished can be downloaded as a single archive rather than as twenty separate save prompts.

How the Free and Pro Tiers Differ

• Free: one document at a time, up to 25 MB and 100 pages. Every feature works — the selection tools, both detectors, both modes and the custom filename.
• Pro: up to 50 documents at once, sizes limited by your device rather than by a number we picked, one selection applied across the batch, and a single archive at the end.
