Building the Ultimate Privacy-First PDF Tool
In an age where data privacy is becoming increasingly critical, we noticed a problem with most online PDF tools: they verify your files by uploading them to a remote server. This works, but it means your sensitive documents—contracts, financial reports, personal records—are leaving your device. We decided to build something different.
The Privacy-First Approach
100% Client-Side
All processing happens right in your browser using WebAssembly.
