Frequently Asked Questions
Everything you need to know about Optimax PDF's Hybrid Privacy Architecture.
How does Optimax PDF protect my document privacy?
Optimax PDF uses a Hybrid Privacy Architecture. Core tools like Merge, Split, Rotate, Sign, Watermark, and image conversions run 100% locally inside your browser's RAM via WebAssembly—your files never leave your device. Heavy tasks like OCR, Compress, and high-precision format conversions use our ephemeral cloud server, which permanently auto-deletes your file the millisecond processing finishes.
Is Optimax PDF completely free without daily task limits?
Yes. Unlike traditional PDF platforms that block you after 2 tasks per day or add watermarks, Optimax PDF is 100% free with no account registration, no watermarks, and unlimited local browser processing.
How do I know which tools run locally vs. in the cloud?
Every tool card and tool header displays a transparent security badge: a green 100% Local badge for tools that process entirely offline in your browser, or a red Auto-Deleted badge for ephemeral cloud tools.
Does Optimax PDF work on Mac, Windows, iPhone, and Android?
Yes. Optimax PDF runs directly inside any modern web browser (Chrome, Safari, Edge, Firefox) on desktop, tablet, and mobile devices without installing any software or extensions.
