How is this different from other online PDF tools?

Most online PDF tools send your files to a remote server for processing. This tool processes everything locally in your browser using client-side JavaScript. Your files are never transmitted to any server, which means your document content stays entirely under your control.

Are my PDF files uploaded?

No. Your files are read directly by your browser. Your files are never transmitted over the network. The tool works entirely within the browser tab you have open.

Can I verify that files are not uploaded?

Yes. Open your browser's developer tools (F12), go to the Network tab, and watch for any outgoing requests while using the tool. You will see no file data leave your browser. The site may record an anonymous page-view count, which never includes your files and can be disabled.

Does this tool work offline?

Yes, once the page has loaded the tool processes your files entirely in your browser; tool functionality needs no network connection. You can disconnect from the internet and continue using it.

What happens when I refresh the page?

Because nothing is stored on a server, refreshing the page clears your current session. Any files you had selected will need to be selected again.

Does this tool store my files?

No. Files are held in browser memory only for as long as the page is open. Closing or refreshing the page discards them. Nothing is written to disk by the tool, and nothing is sent to a server.

Can this tool unlock password-protected PDFs?

No. This tool does not attempt to remove or bypass PDF password protection. If you know the password, the Unlock PDF tool on this site can remove it locally; then this tool can process the file.

What technologies does this tool use?

This tool uses client-side JavaScript and pdf-lib for local PDF structure editing.

Does this tool use WebAssembly?

No. This tool uses client-side JavaScript and pdf-lib for local PDF structure editing. No WebAssembly is involved.

How do I split a PDF into separate files?

Choose your PDF with the file picker, then type the page ranges you want in the input box, such as 1-3,5,7-9. Click Split and a Save button appears for each resulting file so you can download them one at a time, all without anything leaving your browser.

Why did entering 1-3,5,7-9 give me three separate files instead of one?

Each comma-separated segment becomes its own output PDF, so 1-3,5,7-9 produces three files: pages 1-3, page 5, and pages 7-9. If you want a single combined file, use one range like 1-9 instead of comma-separating the parts.

Why does it reject my page range or a number I entered?

Page numbers are counted from 1, so a reversed range like 5-3 or a page beyond the document's length is refused, and the input accepts digits, commas, and hyphens. Adjust the numbers to fall within the actual page count and put the smaller page first in each range.

Does the Split PDF tool cost anything to use?

Splitting PDFs by page range here is completely free — no account, no sign-up, and no cap on how many files or pages you process, and it always will be. Every split runs entirely inside your own browser using pdf-lib: your document is read into local memory, the requested page ranges are extracted, and each resulting PDF is handed straight back to you as a download — no file data is ever sent to a server.

Split PDF Files Privately — Pages Never Leave Your Browser

Choose a PDF, specify the page ranges you want, and download the resulting files — all splitting happens locally in your browser with no upload.
