About PDFMerger.io
We are on a mission to provide the most secure, fastest, and truly free PDF tools on the web.
Our Privacy-First Approach
Most online PDF tools work by uploading your documents to their servers. We think that's a massive privacy risk. Your bank statements, legal contracts, and personal IDs shouldn't be sitting on someone else's computer.
That's why PDFMerger.io was built using modern WebAssembly (WASM) technology. Every tool on our site runs directly in your web browser. Your files never leave your device, and we never see your data.
Built for Speed
Because we process files locally, there are no upload or download wait times. Large merges and splits that take minutes on other sites happen in seconds here.
Whether you're on a high-end workstation or a mobile phone, our tools utilize your local hardware to give you the fastest possible performance.
Truly Free. No Strings Attached.
We don't believe in "daily limits," "watermarks," or "hidden paywalls." PDFMerger.io is supported by non-intrusive advertising, allowing us to keep these professional-grade tools free for everyone, everywhere.
