Why use our Merge PDF?

Our Merge PDF is designed for speed, privacy, and ease of use. Unlike other online tools that require you to upload your sensitive documents to a server,SxTools performs all conversions and modifications locally on your device.

Key Benefits

100% Privacy: Your PDF files never leave your computer.
Fast Processing: Powered by modern WebAssembly technologies.
No Limits: Process as many files as you need, for free.

How it works

We use advanced browser capabilities to handle PDF files. When you select a file, the processing engine (PDF.js or pdf-lib) runs directly in your browser tab. This ensures that your data remains secure and the process is lightning fast.
