How it works

Frequently asked questions

Are my PDF files uploaded?

No. PDF contents are read and processed by code running in your browser. Ads or basic analytics may use separate network requests.

Can I process a very large PDF?

It depends on your device and browser memory. Desktop browsers are recommended for files over 150 MB.

What happens when I close the tab?

In-memory files and generated download links are discarded by the browser.
