I work on OnePassApps, the team behind app.onepassapps.com - so this is our own app, and every limit below was read off our own live guide and app page today, 12 November 2026.

Splitting a PDF by hand means opening it, working out which pages you want, and saving them one at a time. Doing it online usually means handing the file to a server first. There is a third way: the browser already has a PDF engine in it, so the page you are reading can do the work on the file that never leaves your machine.

That is what our PDF Organiser does. Its own guide says it plainly:

PDF Organiser works with PDFs already on your device.

Merge, split, reorder, and rotate existing PDF pages locally.

Your device originals remain unchanged, and you do not need an account to complete the workflow.

What it does

  • Combine pages from multiple PDFs into one document in the order you choose.
  • Select, move, rotate or remove pages using controls that also support keyboard operation.
  • Download the arranged PDF or split selected pages into a ZIP with one PDF per page.

The third bullet is the one this post is about: the split export writes one PDF per page into a ZIP, so a 30-page selection comes back as a ZIP of 30 single-page PDFs.

The three steps

01 Choose one or more PDF files.

02 Select the pages to keep, reorder them and adjust rotation.

03 Download the combined PDF or split-page ZIP, then open the output to verify it.

The limits, as published

  • Imports allow up to 20 files, 25 MiB per file, 50 MiB combined and 300 pages.
  • Split exports allow at most 50 pages and have an output-size limit.

Those two lines matter more than they look. The split export has its own cap, and it is half the import page budget: 300 pages in, 50 pages out of one split. And the size of the ZIP is not quoted, only bounded - the guide says it has an output-size limit without naming the number, so do not plan a split around a specific archive size.

The app also states its own category on the page - Documents / PDF / Local utility - and the guide is explicit that it is a page organiser, not an editor:

This is page organisation: it does not provide OCR, content editing, compression or secure redaction.

Bookmarks, forms and digital signatures are not guaranteed to survive export.

So there is no OCR, no text editing, no compression and no redaction here, and bookmarks, forms and signatures are not guaranteed to survive an export. It does not take photographs either: The input is existing PDF documents.

Your file stays in the tab

Document bytes stay in the app's memory.

PDF Organiser runs in your browser with no account or payment details, and it never uses OnePassApps credits.

There is no account to create and nothing to upload, so the usual privacy question - what happens to the file after I close the tab - has a short answer: nothing, because it never left.

We wrote up the merge side of the same app earlier, with the page-size arithmetic: https://dev.to/onepassapps/merge-pdf-pages-in-the-browser-reorder-rotate-and-export-without-uploading-56ik .

Try it

The PDF Organiser is one of the apps under one membership, and it runs in your browser: Open the PDF Organiser.

Every app has a plain-language guide with its limits and its tool list: the OnePassApps guides.

If you have used a split-PDF site and had to upload the document to get the pages back, this one does the same job without that step.
