About the PDF merger
Merging PDFs is one of those small tasks that always shows up at the worst moment — a procurement portal that only accepts one file, an expense claim that needs receipts stapled to the form, a contract appendix that arrived three days late. The BizAssets PDF merger combines as many PDFs as you need into a single, clean file you can download right away. There's no signup, no watermark, and nothing to install.
The merge happens entirely in your browser. We use pdf-lib, a well-known open-source library, to load each PDF, copy its pages into a fresh document, and serialise the result back to a Blob your browser can download. Your PDFs are never uploaded to BizAssets and never seen by anyone else. They live in memory for as long as the tab is open and disappear when you close it.
How to use it
Drop your PDFs into the drop zone in the order you want them, or use Choose files. If the order is off, drag rows up and down, or use the arrow buttons — the final order is exactly the order you see. Remove anything you've added by mistake, then click Merge & download. You'll get a single PDF named merged.pdf. If a file is password-protected or corrupt, you'll see a clear message and nothing will be merged until you fix the input.
A note on encrypted PDFs
Browser PDF libraries can't decrypt password-protected files, so encrypted PDFs are rejected up-front. The easy fix is to open the PDF in Preview (macOS), Acrobat, or any tool that can re-save without a password, then try again.
