Tools designed for simple, secure document work
We prioritize user autonomy, clean software design, and transparent data processing. Here is how our architecture safeguards your daily documents.
Browser-Based Execution
Core PDF actions (like Merge, Split, Rotate, and Numbering) are computed locally inside your browser sandbox. Your private files are not transmitted to remote cloud storage.
No Mandatory Sign-Up
We believe basic productivity tools should be immediately accessible. Drag, drop, process, and download without being forced to create an account or provide payment details.
Zero Permanent Storage
When network APIs are utilized (such as LLM summarization), files and prompt vectors are processed in transient memory and automatically purged after session delivery.
Predictable & AdSense Compliant
Transparent operations with no deceptive redirect traps, no fake countdowns, no intrusive popups, and no disguised download buttons.
