Combine PDFs into one file without the upload

Most “free” PDF mergers push your documents to a server before they combine anything. This one merges entirely on your device , every page of every file is copied into a single new PDF, in the order you choose. Drag rows to reorder, nudge files with the up and down arrows, see each file's page count and size plus a running page total, then download one tidy merged document. It's instant, fully private, and keeps working offline once the page has loaded. No sign-up, no size limits, free forever.

§ 04 · faq

Frequently asked questions.

Is the PDF Merge tool free?
Yes , completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Are my files uploaded anywhere?
No upload, ever. The merge runs entirely in your browser on your own device , your PDFs never leave your computer and nothing is sent to a server.
Does it work offline?
Yes , once the page has loaded, adding files, reordering and merging all happen locally, so it keeps working without a connection.
How do I control the order pages appear in the merged file?
Drag the file rows into the order you want, or use the up and down arrow buttons on each row. Files are merged top to bottom, and every page of each file is included in that sequence.
Is there a limit on how many PDFs I can merge?
There's no hard limit set by the tool. Because merging happens in your browser, the practical ceiling is your device's memory , combining many very large PDFs at once will use more RAM, but typical documents merge instantly.
Do I need to install anything or create an account?
No. Just open the page and start dropping PDFs , there's no software to install and no account to create.
