Merge and split PDF documents entirely inside your browser. Nothing is uploaded to a server — your files stay on your device from start to finish.
Two focused tools today. More are on the way — same private, in-browser approach every time.
Every file is processed locally in your browser using JavaScript. Your PDFs never touch a server.
No round trips to a server means no waiting on uploads or downloads — just instant, local processing.
Use every tool without signing up, without watermarks, and without a page or file-size paywall.
Responsive tools that work equally well on desktop, tablet, and mobile browsers.
There's nothing to download or install. Open a tool in your browser and get straight to work.
PDFToolkit is built to grow. Compression, conversion, and more are on the roadmap.
Open Merge PDF or Split PDF depending on what you need to do.
Drag and drop your PDFs, or click to browse. They load directly in your browser.
Merge or split instantly, then download your finished file — nothing is ever stored.
PDFToolkit processes every file locally using your browser's own JavaScript engine. We don't have a server that receives your documents, so there's nothing for us to store, see, or lose. Read more in our privacy policy.

No. Every tool runs entirely in your browser. Your PDF files are processed on your own device and are never sent to a server.

No installation required. PDFToolkit works directly in your web browser on desktop, tablet, or mobile.
Yes. Merge and Split are the first two tools, and PDFToolkit is structured so new tools can be added without disrupting the ones you already use.
