Common reasons to split a PDF
Extracting specific sections: You received a 200-page industry report but only need pages 45–60. Extracting those 16 pages gives you a manageable file to annotate and share without the full document.
Reducing file size for email: A 30-page document that exceeds an email attachment limit can be split into two 15-page files, each small enough to send.
Separating independent content: Scanned contracts with multiple signatories, or combined form submissions, often contain logically separate documents that should be filed individually.
Removing unwanted pages: Split off pages you don't need, then merge what's left. This is the standard workflow for removing a cover page, advertisement section, or blank pages from a downloaded PDF.
Splitting methods: by page range vs. by page
By page range: specify start and end pages, for example pages 1–10 as one file and pages 11–20 as another. This is best when you know the section boundaries.
Into individual pages: each page becomes its own file. This is useful for scanned documents where each page is an independent record, or when you need to sort and recombine pages.
By file size: some tools split automatically when file size exceeds a threshold — useful for archiving or preparing files for systems with upload limits.
Step-by-step: split a PDF online
1. Open the Split PDF tool.
2. Upload your PDF.
3. Choose your split method: by page range, extract specific pages, or split into individual pages.
4. Click Split PDF.
5. Download your output files — either as individual PDFs or as a ZIP archive.
What to watch for
Bookmarks and internal links may be broken after splitting, since they may reference pages that are no longer in the output file. This is usually acceptable for share-and-review workflows but worth noting for archival documents.
If the original PDF has a table of contents, the page numbers in the TOC will still reference the original document's pagination. You'll need to update these manually if they matter.
Very large PDFs (100+ pages, 50+ MB) may take longer to process. Allow extra time and don't close the browser tab.
Summary
Splitting PDFs is a straightforward task once you know which pages you need and why. For extracting sections, use page range splitting. For creating individual-page archives, use per-page splitting. Either way, the original file is never modified — you always get new output files.
