How merging PDFs works in your browser — no upload, no sign-up

Most PDF tools ask you to upload your files to a server, create an account, or pay before you can merge a couple of documents.

The Merge PDF tool from The Tools Kit works differently: it merges your PDFs entirely in your browser. Your files stay on your device — no uploads, no sign-up.

It is as simple as this:

1. Open the Merge PDF tool.
2. Drop in the PDFs you want to combine, in the order you want them.
3. Click merge and download the combined file.

That is it. Everything happens locally in your browser.

Merge PDF is one of 170+ free tools on The Tools Kit — including QR code generation, photo collages, words to numbers, and more.
