Merge PDF
Combine multiple PDFs into one file, in your chosen order.
Drop PDFs here, or click to choose files — merge order follows the list below
Merged entirely in your browser — your files are never uploaded.
How it works
- Drop in two or more PDF files.
- Reorder them using the up/down arrows.
- Click merge to download one combined PDF.
Need more than a one-off tool?
PDF Go for Mac keeps every tool like this — plus AI chat, summarization, and semantic search across your documents — in one native app, working offline for markup and signing.

Is there a file size or count limit?
Only what your device's memory can handle — there's no artificial server-side limit, since merging happens entirely in your browser.
Does merging work on password-protected PDFs?
Not currently — remove the password first (outside this tool), then merge.
