JadePDF真的私密吗? +
Yes. 80% of our tools run entirely in your browser using WebAssembly and JavaScript. Your PDFs never leave your device. For the 20% that need server processing, files are deleted within 60 seconds.
"80%仅在浏览器中"是什么意思? +
It means most of our tools process your PDFs directly in your web browser using technologies like WebAssembly, PDF.js, and pdf-lib. No upload, no server, no data collection.

Not yet, but we're working on a desktop app. For now, you need an internet connection to load the page, but the actual PDF processing happens in your browser.
它可以在手机上使用吗? +
