Split a PDF
◐ Runs locally in your browserWhy split a PDF offline?
Most free PDF splitters work by uploading your file to a server, splitting it there, then handing back the result. For engineering drawings, signed permits, client submittals, or anything else that's confidential, that round trip is the part you want to skip. LocusBIM runs entirely on your own computer — the PDF is opened, split, and saved locally. No account, no upload, no third party in the loop. For Canadian Architecture and Engineering firms that need PIPEDA-clean workflows, this is the only model that actually works.
What LocusBIM splits
Single pages. Split a 50-page drawing set into 50 individual PDFs in one click. Each output file keeps the original page's dimensions, embedded fonts, vector content, and annotations intact.
Page ranges. Extract pages 5-12 as a single PDF — useful when isolating a discipline section (structural drawings, electrical single-lines, etc.) from a full set.
Every Nth page. Batch-split a long document into chunks of equal size. Convenient for printing or distributing a drawing set in stages.
How it compares to cloud PDF splitters
How to split a PDF in LocusBIM
- Download LocusBIM from locusbim.com/downloads (Windows, macOS, or Linux).
- Open the PDF. File ▸ Open PDF.
- Open the Document toolbar. Click the Document tab in the tool palette.
- Choose Split. Pick split mode: single pages, range, or every Nth page.
- Save. LocusBIM writes the output files to a folder you choose. Done — no internet round-trip, no account.
Built for engineering drawings
LocusBIM is built for Canadian Architecture and Engineering firms, so the PDF tooling is tuned for drawing-set workflows. Signed seals, professional stamps, calibrated measurements, BIM-linked markups, BCF exports — all of these survive a split intact. Compare that to a generic web tool that rasterises everything to PNG and re-emits a flat PDF: you lose vector fidelity, font information, and any structured metadata. The output stops being usable for downstream design work.
Frequently asked questions
Is LocusBIM free to use for splitting PDFs?
The desktop app is free to download and includes PDF page operations (split, merge, rotate, delete). Paid tiers add BIM coordination, batch operations, and team collaboration. You can split PDFs on the free tier indefinitely.
Does my PDF get uploaded to a server?
No. LocusBIM is a desktop application — every PDF you open is processed on your own machine. Nothing is uploaded, nothing is sent to a third party, no account is required. This matters for confidential drawings, signed permits, or client work that can't legally leave your jurisdiction.
Can I split a PDF by page range, or only one page at a time?
Both. LocusBIM's Document toolbar lets you split a PDF into single-page files, extract a specific range (e.g. pages 5-12 as one file), or split at every Nth page for batch processing. Output files keep their original page dimensions, embedded fonts, and bookmarks.
What's the maximum PDF size I can split?
There's no enforced limit. LocusBIM handles drawing sets of thousands of pages comfortably; the practical ceiling is your computer's RAM. We've tested with PDF files over 2 GB without issue on a typical engineering workstation.
Does this work on macOS and Linux?
Yes. LocusBIM ships installers for Windows 10/11, macOS 11+ (Apple Silicon + Intel), and Ubuntu 22.04+ (AppImage). The PDF engine is the same across all platforms — output files are byte-identical.
Are the split files identical to the original pages?
Yes. LocusBIM uses Pdfium (the same PDF engine that ships with Chromium) to extract pages preserving the original page content streams, embedded fonts, vector graphics, and annotations. No re-rasterisation, no quality loss.
What about signed PDFs?
Splitting a signed PDF invalidates the digital signature on the resulting parts — this is a property of how PDF signatures work, not a LocusBIM limitation. If the source PDF has a digital signature you need to preserve, contact the original signer to re-issue the split files.
What else can LocusBIM do?
Page splitting is one corner of the desktop app. LocusBIM also handles combining PDFs, signing, drawing markup, BIM coordination, BCF round-trip with structural engineers, and shareable web links for clients who don't have LocusBIM installed. See pricing for the full feature breakdown by tier.
