Privacy & Trust

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.

Answers & Guidance

Frequently Asked Questions

Everything you need to know about Semrush AI Tools and privacy-first document processing.

For the vast majority of our core tools (including Merge PDF, Split PDF, Rotate PDF, Watermark PDF, Crop PDF, and JPG to PDF), all processing takes place entirely inside your web browser using WebAssembly and client-side JavaScript. Your files never leave your computer. For tools utilizing cloud intelligence (like AI PDF Summarizer), data is processed in transient memory and immediately purged.
