Merge PDFs Without Installing Anything

You have five PDFs. A contract, two appendices, a cover letter, and an invoice. Your client wants one file. Sound familiar?

Most people reach for Adobe Acrobat. Others download sketchy desktop tools. Both are overkill.

The simpler way

FileTools runs entirely in your browser. Upload your PDFs, drag them into order, hit merge. Done. The combined file downloads immediately.

No account. No installation. No file size lectures.

What happens to your files?

Nothing leaves your machine. FileTools processes everything client-side using WebAssembly. Your documents stay in your browser's memory and disappear when you close the tab.

This matters if you handle contracts, medical records, or anything remotely sensitive. Most online PDF tools upload your files to a server. FileTools doesn't.

Beyond merging

Once you have your merged PDF, you might need to compress it for email. FileTools handles that too — along with splitting, converting to Word, and extracting pages.

If you work with video content, TubeVoice does something similar for multilingual dubbing — taking complexity and making it disappear. Same philosophy: do one thing well, do it in the browser.

The catch

There isn't one. FileTools is free. No watermarks, no "premium tier" upsells on basic features. Merge as many PDFs as your browser can handle.
