How to Split a PDF Online for Free

Splitting a PDF lets you turn one large file into smaller ones—by chapter, by section, or into single pages. You might need to email only part of a document, reduce file size by keeping just the pages you need, or reuse specific pages in another project. You can split a PDF online for free in your browser without installing software. This guide explains the difference between splitting by page range and extracting single pages, how to split with FileFlip step-by-step, how splitting can help reduce file size, and how to do it on mobile.

Split by page range vs extract single pages

Split by page range — You define ranges (e.g. pages 1–5, 6–10, 11–15) and get one PDF per range. Ideal when you want to divide a document into logical chunks (chapters, sections). The original order is preserved within each new file.
Extract single pages — You choose individual pages (e.g. 3, 7, 12) and get one PDF per page, or one PDF containing only those pages. Useful when you need to pull out specific pages (e.g. a form, a diagram) without the rest of the document.

Some tools offer both: split into ranges and extract selected pages. Pick the option that matches how you want to use the content.

Step-by-step with FileFlip

Open the Split PDF tool.
Upload your PDF (click or drag and drop). The tool will show the page count.
Choose how to split: by page range (e.g. 1–5, 6–10) or extract specific pages, depending on what the tool offers.
Apply the split. You get one or more PDFs to download—either as a ZIP or as separate files.
Download the result(s). No account is required.

The tool works in desktop and mobile browsers. Processing can run locally so your file does not have to be uploaded to a server; check the tool page for details.

How to split a large PDF to reduce file size

If a PDF is too big to email or upload, splitting can help: keep only the pages you need and discard the rest. For example, split a 50-page report into “summary only” (pages 1–3) and download that smaller file. You can also split, then compress each part if you need even smaller files. Splitting does not by itself compress the content—it only reduces the number of pages in each file. For maximum size reduction, split first, then compress the parts you keep.

Split PDF on mobile

You can split a PDF on your phone or tablet without an app. Open the FileFlip Split PDF page in Safari (iPhone/iPad) or Chrome (Android), then:

Tap to upload the PDF from your device or cloud storage (e.g. iCloud, Google Drive).
Select your split option (ranges or individual pages).
Run the split and download or share the new PDF(s).

Processing happens in the browser. For very large PDFs, a stable connection helps. If the file is very big or you have many ranges, splitting on a computer may be faster.

FAQ

Is splitting PDFs free?
Yes. FileFlip’s split PDF tool is free to use; no account or subscription required. There may be limits on file size or number of pages per run.

Can I split and keep the rest of the PDF?
Splitting creates new files from the pages you choose; it does not delete the original. Keep your original PDF if you need the full document later.

What if I need to reorder pages after splitting?
You can merge the split PDFs in a different order with a Merge PDF tool, or use an extract/reorder pages tool if you need to rearrange before splitting.

Are my files uploaded to a server?
When the tool runs locally, your PDF is processed on your device and not sent to a server. See the tool page for the current behavior.
