How privacy works here

Traditional tools upload your files to their cloud. We don't. Here is the difference.

Step 01

You select a file

Select any document from your device. The browser loads the file into a temporary memory sandbox allocated specifically for this tab.

Step 02

Browser processes locally

Our WebAssembly engine (WASM) kicks in. Your CPU processes the conversion, compression, or merge operation instantly.

Step 03

Instant Save

Since the file never left your computer, there's no download latency. You simply save the processed file directly to your drive.

Frequently Asked Questions

Yes, the basic plan allows for 5 documents per day. Because we don't have heavy server costs (since your computer does the work), we can offer a generous free tier.

No. We cannot see, store, or access your files. All processing is done via WebAssembly inside your own browser tab. Close the tab, and the data is gone from memory.

The Pro plan supports files up to 2GB. Performance depends on your device's RAM since operations happen locally.
