How to split a big scanned PDF into separate documents

To split a PDF into separate documents, note which pages belong to each document, type those as ranges (for example 1-2, 3, 4-6), and save. Each range becomes its own PDF. Our Split PDF tool does this in your browser without uploading the file, and the pages come out exactly as they went in.

The usual reason for needing this: someone fed your whole stack of papers through a scanner in one go, and you now have a single 14-page file called Scan_20261112.pdf, while the portal wants the Aadhaar, the marksheets and the caste certificate in three different upload boxes.

First, write down what is on each page

Open the PDF and make a quick list before touching any tool. It saves you from doing the split twice.

A typical scanned bundle might look like this:

Two things to watch while you make the list.

Count the pages of the PDF, not the numbers printed on the paper. A certificate that says "Page 1 of 2" at the bottom might be page 9 of your scan.

Keep both sides of a document in the same range. If the back of a marksheet carries the grading key or a signature, it belongs with the front.

Split the PDF by page ranges

1. Open Split PDF and add your file. It accepts one PDF of up to 100 MB and shows every page as a thumbnail.
2. Choose By page ranges.
3. Type the ranges from your list, separated by commas: 1-2, 3, 4-5, 6. Leave out pages you don't want, such as the blank page 7.
4. Split and download.

If the result is more than one file, you get split-pdf.zip with the PDFs inside, named after their pages, like pages-1-2.pdf and pages-4-5.pdf. If the result is a single PDF, you get it directly.

Open the ZIP, then rename each file to say what it is: Aadhaar.pdf, Class10_Marksheet.pdf and so on. Names like pages-4-5.pdf are easy to mix up at upload time, and some portals show the file name to the person verifying.

The other two ways to split

Ranges suit a mixed bundle. The tool has two more modes for other situations.

Every N pages cuts the file into equal parts. Set N to 1 and every page becomes its own PDF, which works well when the scan is a stack of single-page certificates. Set N to 2 when every document is a front and a back.

Select pages lets you tap the thumbnails you want, and puts them together in one new file called selected-pages.pdf. Use this when you want one document out of the bundle and don't care about the rest.

If you find yourself only ever pulling out a page or two, Extract PDF Pages is the more direct tool. It also has an option to save each chosen page as its own PDF. We cover that in how to save one page of a PDF.

Which mode for which job

Common problems and fixes

"I got a ZIP and my phone won't open it"

A ZIP is a folder packed into one file. Most phones open it from the Files or file manager app with a tap. If yours doesn't, the simplest way round is to split one document at a time using Select pages, which gives you a plain PDF each time, or do the split on a computer.

A split file is still too big for the portal

Splitting doesn't compress anything. Pages are copied as they are, so a two-page scan made at high resolution can still be several MB by itself. Run that file through Compress PDF and check the small print is readable afterwards.

Some pages are sideways or upside down

That is how they were scanned, and splitting won't change it. Turn them with Rotate PDF either before or after the split. Before is easier, because you fix one file instead of five.

The pages are in the wrong order

If the fronts and backs got mixed up during scanning, sort the order first with the steps in how to rearrange PDF pages, then split.

The tool refuses the file

Password-protected PDFs can't be split in the browser and are refused with a message. That includes PDFs that open without a password but have restrictions. If you know the password, Unlock PDF saves a copy without it, and that copy will split normally.

I split at the wrong page

Nothing is lost. Your original PDF is still on your device. Add it again, correct the range and download once more.

What happens to quality, text and bookmarks

Pages are not re-rendered, so quality is unchanged. If the text in your PDF was selectable before, it stays selectable, and links inside a page keep working.

Two things don't survive: bookmarks (the outline you see in a sidebar) are not kept, and fillable form fields may stop being fillable. For scanned documents neither applies.

One honest limit: splitting does not make a scan searchable. A scanned PDF is a set of pictures of paper, and the split files will be pictures too. There is no text recognition (OCR) in our tools.

If you are scanning again anyway

Splitting is a repair for a scan that was done in one lump. If you still have the papers and a scanner or phone handy, scanning each document as its own file can be less work than splitting later.

When you go to a shop or use the office scanner, say up front that you want separate files per document. On a phone, make one PDF per document as you go; our guide to converting photos to PDF explains how.

And once you have the separate files, keep them. A folder with Aadhaar.pdf, PAN.pdf, Class10.pdf and Class12.pdf gets used again for every form you fill in over the next few years. When a form asks for some of them back in a single file, merging them takes a minute.

Questions people ask

How do I split every page into a separate PDF?

Choose Every N pages and set N to 1. You get one PDF per page, packed into a ZIP.

Can I split a PDF on my phone?

Yes. The tool runs in the phone's browser. The thumbnails help on a small screen because you can see which page is which without opening the file separately.

Does splitting change the original file?

No. The split files are new. The PDF you started with stays on your device as it was.

Is the file uploaded anywhere?

No. The PDF is split in your browser. That matters for a bundle that holds your Aadhaar, PAN and certificates all in one file.
