How to use

What it's for

Take some pages out of a PDF, keep only the ones you need, or turn pages that came out sideways or upside down.

Before you start

Have the PDF on this device, with no password on it, and know the page numbers you want.

  1. Choose the PDF

    Press Choose a file and pick the PDF, or drag it onto the box. The document then shows how many Pages it has and its Page size.

  2. Choose what to do

    In What to do, pick Keep these pages to make a copy with only those pages, Remove these pages to make a copy without them, or Turn these pages to rotate them.

  3. Type the page numbers

    In Pages, type pages and ranges separated by commas, such as 1-3, 5, 8-10; 5- means page 5 to the end, and an empty box means every page. Pages come out in the order you type them, so keep them low to high.

  4. Pick the turn, if you are turning

    With Turn these pages, choose Quarter turn clockwise, Half turn or Quarter turn anticlockwise in Quarter turns. The turn is added to the way each page already sits.

  5. Check, make, then save

    Read the What it will make line, then press Make the new PDF and Download; your original is not changed. Changing a setting afterwards clears the new file until you press the button again.

Reading the result

  • What it will make: the pages the new PDF will hold, written as ranges, and how many. When turning, it lists the pages that will turn.
  • The new PDF: appears after the press, with the file's Size and Download. Its name gets -pages, -trimmed or -turned added.
  • Page size: the first page in millimetres, with its paper name, such as A4, when it is a standard one. mixed sizes means the pages differ.

If it goes wrong

  • A note says a range was written with the larger number first: 5-2 was read as pages 2 to 5. To reverse the order, list the pages one by one, such as 5, 4, 3, 2.
  • The PDF is refused as encrypted: it has a password. Remove the password in the program that made it first.
  • Make the new PDF stays greyed out: a message below says what in Pages cannot be read, or removing those pages would leave none.

What this is

A page selection has four ways of going silently wrong, and none of them throws an error.

A range past the end. A range typed backwards. A repeated page. A list that does not ascend. Each produces a document that looks right and is missing something.

So each one is a decision written down. 1-9999 on a twelve-page document is “all of it”, not a mistake. 5-2 is read as pages 2 to 5 and says so. 1,1,2 is kept, because extracting a page twice is a real request.

And 3,1,2 reorders the document — because the order you type is the order that comes out.

What will be kept or removed is printed above before you download anything. The mistake is visible before the document is written rather than after it is opened.

Questions

Is my PDF uploaded anywhere?

No. It is read from your disk into this browser tab and the new document is built there. There is no upload and no server, which matters because the documents people trim are contracts, payslips, bank statements and scanned IDs.

How do I write the page numbers?

Single pages and ranges separated by commas: 1-3, 5, 8-10. Open ranges work too — 5- means page 5 to the end, and -4 means the start to page 4. Pages are numbered from 1, the way your reader shows them. The page prints back what it will actually keep or remove before you download anything.

What happens if I type a page that does not exist?

A range that runs past the end stops at the last page and says so; a page entirely beyond the end is dropped and named. Neither is an error, because 1-9999 on a twelve-page document means "all of it" and the person typing it knows what they meant. A selection that is entirely outside the document is refused, since that is a mistake rather than shorthand.

I typed 5-2 by accident. What does it do?

It reads it forwards as pages 2 to 5 and tells you it did. A backwards range is almost always a range typed in the wrong order; refusing it helps nobody and silently dropping it is worse. If you actually wanted the pages reversed, list them individually — 5, 4, 3, 2 — because the order you type is the order they come out.

Can I reorder pages with this?

Yes. The pages come out in the order you list them, so 3, 1, 2 rebuilds the document in that order. The page warns you when your list is not ascending, because most of the time that was a typo rather than an instruction.

Does turning a page rotate it permanently?

It sets the rotation the page carries, which is what every reader honours — the same thing your reader does when you rotate and save. It is applied on top of any rotation already there rather than replacing it, because a scanner writes 90 on every page of a landscape document, and setting rather than adding would leave those pages untouched while turning their neighbours.

Is the content re-rendered or compressed?

No. Pages are copied whole, with the fonts, images and colour profiles they reference. Nothing is decoded and redrawn, so the pages that come out are exactly the pages that went in — which is also why the file size does not drop much when you remove pages that shared resources with the ones you kept.

Why will it not open my password-protected PDF?

Because the page contents of an encrypted PDF cannot be read without the password. Opening it anyway produces a document that looks right and shows blank pages, and you would not discover that until somebody else opened it. Remove the password in the program that made the file first.

The maths

On a 12-page document
1-3, 5, 8-101,2,3,5,8,9,10
10-999910,11,12 — clamped
5-22,3,4,5 — read forwards
5-5 to the end
3,1,2reorders
“Remove” is “keep” over the complement: remove 2 and 4 is keep 1, 3, 5. One code path builds the document — two paths that mean the same thing drift, and the one used less often is the one that breaks.

Important

The file is read in your browser and nothing about it is transmitted or stored. Pages are copied whole and never re-rendered — but removing pages may not shrink the file much, because pages that remain can reference the same fonts and images. Nothing you type here is sent to our servers — the calculation runs entirely in your browser.
