zero-knowledge PDF suite

PDF处理所需的一切
Free tools that run in your browser. Free to start.
零知识处理原理
Your documents stay on your device. Here's why that matters.
Runs in your browser
Free tools use JavaScript to process files locally. Your PDF never leaves your device — we couldn't see it even if we wanted to.
No servers. No storage.
We don't have file storage infrastructure. There's no database of user documents. Zero files on our servers means zero risk.
AI with transparency
OCR and Translate extract text and send it to Anthropic's API. Your original PDF stays local. We tell you exactly what happens.
