How to Merge PDF Files Online — Free & Private
Need to combine multiple PDF documents into one file? PeacefulPDF's merge tool lets you do it instantly, right in your browser. No file uploads, no account creation, no waiting for server processing.
Most PDF merge tools — iLovePDF, Smallpdf, Adobe — require you to upload your documents to their servers. That's fine for public brochures, but terrible for contracts, tax forms, or anything with personal information. PeacefulPDF processes everything locally using your browser's JavaScript engine. Your PDFs never leave your device.
Add your files, see every page as a thumbnail, drag pages or whole documents into the order you want — you can even drop individual pages you don't need — and click merge. The combined PDF downloads directly to your computer in seconds.
Works on Chrome, Firefox, Edge, and Safari. Works on mobile. Works offline after the page loads. No file size limits. Completely free.

FAQ
Can I merge more than two PDFs at once?
Yes. Add as many PDFs as you need — there's no limit on the number of files you can combine, and you can keep adding files after your first selection.
Can I change the order of pages before merging?
Yes. The Pages view shows every page of every file as a thumbnail. Drag any page anywhere in the sequence, or remove pages you don't want — the merged PDF follows exactly the order you see.
Will merging reduce the quality of my PDFs?
No. The merge process copies pages as-is. No re-compression, no quality loss. The output is identical to the originals.
Is there a file size limit?
No hard limit. Since processing happens in your browser, the limit depends on your device's available memory. Most users can merge files up to several hundred MB without issues.
