Everything about privacy, safety, and client-side processing.
Privacy & Security
No. Processing happens in your web browser using JavaScript (pdf-lib). Files are read locally by the File API and processed in memory. Zero file data is sent over the network.
No. Because no server receives your files, we have no technical ability to access them.
Yes. Since documents never leave your machine, it is architecturally safer than traditional cloud-based converters.
We use Cloudflare Web Analytics to measure aggregated page views. It is cookie-free and does not track personal information.
Technology
We use pdf-lib for document operations and pdf.js for thumbnail generation. Both run in-browser.
Manipulating PDF streams client-side uses your local CPU. Heavy operations run in a Web Worker to avoid freezing the interface.
Yes. PDF Toolkit is completely free to use with zero accounts, no trial periods, and no hidden subscriptions.
