How to Split a PDF in Half

Splitting a PDF into two equal halves is a page-range job — you just need to know the midpoint.

Finding the midpoint

Open Split PDF and drop in your file — it shows the total page count immediately. For an even page count, divide by two: a 40-page document splits into pages 1-20 and 21-40. For an odd count, round down for the first half and up for the second — a 41-page document splits into 1-20 and 21-41.

How to do it

1. Open Split PDF and drop in the file.
2. Note the total page count it shows.
3. Extract the first range (page 1 to the midpoint) and download it.
4. Repeat with the second range (midpoint + 1 to the last page).

Each extraction downloads as its own file, so you'll end up with two separate PDFs covering the full original document between them.

Why you might want this

Common reasons: an upload portal with a page limit that a single file exceeds, splitting a long document between two people for parallel review, or breaking a long read into two more manageable sittings.

FAQ

Does splitting a PDF in half lose any content? No — each page is copied exactly as it was in the original; nothing is re-rendered or altered.

Can I split into more than two parts instead? Yes — Split PDF extracts any page range you specify, so you can divide a document into as many pieces as needed by running the extraction multiple times with different ranges.

Will page numbers printed on the pages still make sense after splitting? The printed numbers stay exactly as they were in the original — splitting doesn't renumber content, only which file it lives in.
