When you need to split a PDF, not merge it
Splitting is the mirror image of merging, and it comes up just as often. A supplier sends a 90-page price catalogue and you only need the six pages about your product line. A client sends a contract and you need to forward just the signature page to a colleague. A university uploads a combined prospectus and you want the fee structure on its own. Nobody wants to screenshot pages or print to PDF page by page.
The most common case in India is the reverse of the classic form problem: you have scanned all twelve pages of a supporting document as one PDF, but the portal only accepts the first three. Split it, keep the range you need, and delete the rest from your desktop — simple.
Choosing the right split mode
One file per page is the right choice when a document mixes unrelated things — for example a combined scan of your marksheets where each page belongs to a different semester. You get twelve tidy files named after the original, each containing one page.
Every N pages is handy for printed material: split a 48-page booklet into 12-page sections for stapling, or break a 100-page report into 25-page quarters for different reviewers. Set the number and the tool does the arithmetic, including the smaller final chunk.
Custom ranges gives you exact control. Write 1-3, 4-6, 9 and the tool produces three documents. The ranges are inclusive, they can be in any order, and you can overlap them if you want a page to appear in two outputs. Pages you do not mention are simply left out.
If you also want one combined file containing everything that survived your ranges, tick the box and you get it as an extra download.
What the split output looks like
File names are generated from the original so you can tell them apart in a downloads folder full of similar names. A source called annual-report-2026.pdf split by ranges produces annual-report-2026-pages-1-3.pdf, annual-report-2026-pages-4-6.pdf and so on. One file per page produces annual-report-2026-page-1.pdf.
Every part is a genuine, standalone PDF with the page sizes, orientation and rotation of the original. Links inside the document that point to pages you removed will no longer resolve, which is normal for any split operation. Annotations and form fields that live on the kept pages are preserved.
Because a split can produce dozens of files, the results panel shows a list with sizes and gives you a one-click ZIP. On a phone the ZIP is usually the better choice — a single download instead of forty notifications.
Split by range, or extract a single page?
Splitting and extracting overlap, and it is worth knowing which tool to reach for. Splitting is about producing several outputs at once, where most pages end up in one part or another. Extracting is about keeping a specific selection and discarding everything else — the output is one clean PDF.
If you need page 7 of a 40-page document as a standalone file, both work. Extract Pages is quicker, because you can also click the page in a thumbnail grid instead of counting. If you need pages 7 to 12 as one file and pages 25 to 30 as another, Split with a custom range is faster because it produces both in one pass.
And if you have removed pages, changed your mind, and want them back, remember that this tool never touches your original file. It only reads it. Your source document is exactly where you left it, unmodified.
One last piece of practical advice: name the parts meaningfully as you go. A dozen files called scan-001.pdf is a filing problem waiting to happen, whereas marksheet-semester-3.pdf tells you everything at a glance. Rename before you split and the download folder stays readable for years. And if you are sending the parts to different people, send only the part each person needs — it is both more professional and more private than sending everything and asking them to find the relevant pages.
