Merge PDF — Combine PDF Files

About

Most "merge PDF" tools upload your files to their server. You drag in a contract, an invoice, a scan of your passport — and it gets transferred to someone else's machine, where it sits for "a few hours" before they delete it. You just have to trust them.

Merge PDF doesn't do that. It runs entirely inside your browser. Your files never leave your computer — there is no server, no upload, nothing to delete because nothing was ever sent anywhere.

Drop your PDFs in, drag them into the order you want, click merge. You get one combined PDF, downloaded straight to your computer. That's it.

What it does
— Combine any number of PDF files into one
— Drag and drop to reorder before merging
— First-page thumbnails so you can see what's what
— Page quality is preserved exactly — pages are copied, not re-rendered
— If one file is damaged or password-protected, it's flagged and skipped — the rest still merge (no more "I added 12 files and it only merged 5")

What you don't deal with
— No upload — files stay in your browser
— No sign-up, no account
— No "one free merge, then pay" — it's free, every time
— No ads, no rogue search-page injections
— No file limits

It's free. No paywall, no usage caps, no catch.
