Does rotating reduce the quality?

No. Rotation is recorded as a property of the page rather than redrawing anything, so text stays selectable and images keep their original resolution.

Why did a quarter turn not land on 360?

Because a page already carries a rotation of its own. Turning by 90 a page already at 270 brings it back to upright, which is 0, not 360.

What does turn upright do?

It looks at the shape of each selected page as it is currently displayed and turns any that are wider than they are tall. Pages already upright are left alone.

Can I rotate only some pages?

Yes. Click any page to select or deselect it, or use select the sideways ones to pick out every landscape page in one go.

Is the trimmed content deleted?

No. Cropping sets the area a reader displays and leaves the sheet itself alone, so the content outside is hidden rather than destroyed. Software that ignores the crop box can still reach it.

Yes, in software that lets you reset the crop box, because nothing was thrown away. That is a good thing for a mistake and a bad thing if you were trying to hide something.

What are the numbers measured in?

Points, the unit a PDF works in. Seventy two make an inch, so ten points is about three and a half millimetres.

What happens on a page that is already cropped?

It is trimmed further in from what you can currently see, rather than being reset to the full sheet. Margins somebody already removed stay removed.

Why was one page left alone?

Because the trims you asked for would have left nothing of it. Pages too small for the amounts are reported and skipped instead of being turned into something unopenable.

Split PDF Pages, No Upload

Click any gap between two pages to cut there, and click it again to undo. The colours show which file each page ends up in. A cut before the first page or after the last one would not divide anything, so those gaps are not offered.

Each file is built by copying the pages across, so text stays searchable and images keep their original resolution. The document you dropped in is not changed.

Rotation is recorded on the page itself, so the text stays selectable and images keep their original quality.

Your PDF never leaves this device.The file is opened by your browser, the rotated document is built here in the page, and the download comes from your own machine. Nothing is sent to a server, so nothing is stored on one.

Cropping hides, it does not delete

The sheet of paper is left exactly as it was and only the area a reader displays changes, so the trimmed content is still in the file. That makes a mistake easy to undo, and makes cropping the wrong tool for hiding anything.

How to use this tool

Drop a PDF on the box at the top, choose how you want it broken up, and check the list of files underneath before you build anything.

That list is the whole point of the preview. It names every document that will be produced and the pages each one will contain, so a mistake in a page list is obvious before it becomes twenty files in your downloads folder.

Four ways to break up a document

Every so many pages is for documents with a regular structure: a batch of two page forms, a set of four page certificates. Give it the number and it takes them in order.

One file per page is the extreme version of the same thing, and the one most likely to make your browser ask permission, because a forty page document becomes forty downloads.

Start a new file at is for documents where the sections are irregular. If a report has chapters beginning on pages 4, 9 and 15, list those three numbers and you get four documents split exactly there. This is usually the one you want for a real report.

Extract a selection ignores splitting entirely and pulls out the pages you name into a single document. It also respects the order you give them, so 9, 2, 5 produces a document with those pages in that order.

The same 12 page document split four different ways, showing how many files each mode produces — The two page list modes look similar and do very different things.

Copied, not redrawn

This matters more than it sounds, and it is the difference between a tool that splits a PDF and one that quietly damages it.

A page could be split off by rendering it to an image and building a new document around that. It would look approximately right and would be wrong in every way that counts: the text would stop being text, the file would balloon, and anything drawn as clean vector line work would acquire the soft edges of a photograph.

Here the page objects themselves are copied into the new document. The text remains text and stays searchable and selectable. Images keep their original resolution and compression rather than being decoded and re-encoded. A drawing stays a drawing.

Being straight about the limit: page content copies faithfully, but document level features do not. Bookmarks, form fields and internal links belong to the structure of the original document rather than to the pages, so they do not survive the move. If a document depends on those, splitting it is not a lossless operation no matter which tool you use.

A worked check you can repeat

Take a 30 page document split every 4 pages. Thirty divided by four is seven and a half, so you get eight files: seven of four pages and a last one of two. The summary shows 30 pages placed across 8 files, and confirms every page was used.

Now the same document with new files starting at pages 4, 9 and 15. That gives four documents: 1 to 3, 4 to 8, 9 to 14, and 15 to 30. Notice the cut page begins the new file rather than ending the old one, which is what you want when page 4 is the first page of a chapter.

A cut listed at page 1 is quietly ignored, because there is no document before the first page for it to end.

The planning was checked against an independent implementation before publishing: forty four hand written cases covering exact and inexact division, groups larger than the document, cuts out of order, duplicate cuts, cuts beyond the last page, and the labels that describe each file. Then forty thousand generated splits confirming three things every time: no page is ever lost, no page is ever duplicated across two files, and the label on each file describes exactly the pages inside it.

That last check is there because the label is what you read before downloading. A file labelled 1 to 4 that actually contains five pages would be a quiet lie, and quiet lies are the ones that cost people time.

Mistakes that catch people out

Splitting one page at a time by accident. A long document becomes a long list of downloads. Check the file count in the summary first.

Expecting bookmarks to survive. They do not. Neither do form fields or internal links.

Confusing the two page list modes. Starting a new file at 4 and 9 gives several documents. Extracting 4 and 9 gives one document of two pages.

Not noticing pages left out. When extracting a selection the summary says how many pages will not appear anywhere. That warning is worth reading.

Assuming a password protected file will open. It will not. Remove the protection first, in software that has the password.

Common questions

Is my PDF uploaded anywhere?

No. The file is opened by your browser, the new documents are built here on the page, and the downloads come from your machine. Nothing crosses the network, so there is nothing on a server to store or delete.

Does splitting reduce the quality?

No. Pages are copied across as they are rather than redrawn, so text stays searchable, images keep their original resolution and nothing is re-compressed.

Why did my browser ask about multiple downloads?

Because each new document is a separate file. Splitting a long document one page at a time produces a lot of them, and browsers ask before saving several at once.

Can I pull out just a few pages?

Yes. Choose extract a selection and list them, for example 2-6, 9, last. They come out as one document in the order you listed them.

What happens to pages I did not select?

Nothing. The original file is untouched, and pages outside your selection simply do not appear in the new document. The summary tells you how many were left out.

Will bookmarks and links survive?

Page content, text and images all survive. Document level features such as bookmarks, form fields and links between pages are not carried across, because they belong to the original document structure rather than to the pages.
