How it works


Zero Uploads

Unlike other tools, we don't have a backend. Your files never touch our servers because there are no servers.

Local Processing

We use your browser's WebAssembly and JavaScript engines to process data directly on your device's CPU.

Total Privacy

Since processing happens in a local sandbox, no third-party (including us) can access your sensitive information.

The Technical Details

When you select a file, the browser creates a temporary Blob or ArrayBuffer in your device's RAM. Our algorithms (like pdf-lib for PDF merging) then operate on this memory buffer to generate the output.

This approach is not only safer but often faster, as it eliminates the time spent on uploading large files and waiting for server queues.

"Our mission is to provide professional-grade utilities that treat user data as a liability, not an asset."
