Split a Large PDF for Email
Gmail and Outlook reject attachments over 25MB, and many corporate inboxes cap them lower. When a PDF is too big to send, splitting it into smaller parts is the simplest fix — each part emails cleanly, and the recipient can open them in order. PdfXpo splits a large PDF into manageable pieces free, in seconds, with no upload.
Because the split runs in your browser, the document never leaves your device — useful when the file is confidential. It is free, unlimited, and watermark-free, and your original is untouched. If you would rather keep it as one file, you can compress it instead — but when a hard size cap blocks you, splitting always works.

How to Split a Large PDF for Email — Step by Step
1. Open the free Split PDF tool at PdfXpo.com — no account, no install. Drag your PDF in; it loads in your browser, so your file is never uploaded to a server.
2. Choose how to split: pull out specific pages, split into separate files, or break the document at a page range. Preview the pages and select exactly what you need.
3. Click Split and download your new PDF (or files) instantly — no watermark, no daily limit, and your original stays untouched on your device.

Why PdfXpo for Splitting PDFs

Common Questions
Why split instead of compress for email?
Compression helps, but if a file is huge or near a hard cap, splitting guarantees each part fits. You can also do both — compress, then split if still needed.
Is my PDF uploaded when I split it?
No. The split runs in your browser; your file never leaves your device.
Will the recipient be able to reassemble it?
They can open each part in order, or use a free Merge tool to recombine them if they prefer one file.
Is it free?
Yes — free, unlimited, no account, and no watermark.
