Are my PDFs uploaded?

Merge happens in your browser memory using pdf-lib. We do not persist merged output on SnapTools servers.

Why is there a page limit?

Very large PDFs can exhaust browser memory. Split projects if you hit device limits.

Can I merge password-protected PDFs?

Encrypted inputs may fail. Decrypt locally first, then merge here.

What should I run after merging?

Use PDF Optimize when you need a smaller attachment, PDFEdit when you need to sign or edit, or PDF Split when you only need part of the packet.

PDF Merge — Combine PDFs Online (Private, Browser-First)

Privacy

For supported workflows, files are processed locally in your browser and are not uploaded to SnapTools servers.

Overview

Contracts, invoices, and research packets often arrive as separate PDFs. SnapTools stitches them in the order you pick — ideal before archival or upload to a DMS.

Free and guest users can merge up to two files per run; signed-in free accounts can merge three; Pro supports large batches.

How it works

Each PDF is parsed with pdf-lib, pages are copied into a new document in the order you selected, and the merged bytes download immediately — all inside your browser tab.

Free and guest users can merge up to two files per run; Pro unlocks larger batches when you need whole folders of attachments.

Next steps: tighten file size with PDF Optimize, extract pages via PDF Split, or bundle scans using JPG to PDF.

Benefits

Skip emailing files to yourself just to concatenate — keep the chain of custody on your laptop while still moving fast.

Browser-first processing means SnapTools never stores merged output on our servers for this workflow.

Security & privacy

Review merged PDFs for hidden annotations or metadata before external sharing. Browser tools inherit your OS clipboard and filesystem risks.
