Which file types does Upload Signature accept?

The drop area takes PDF. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".

What do I get back from Upload Signature?

The result is PDF, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.

Is there a file size limit?

A single file may be up to 100 MB, and a batch up to 50 files. Those are guardrails rather than a paid tier — the work happens on your machine, so an enormous document is limited by your own memory before it is limited by us.

Where does the processing actually happen?

In this tab. The file is read locally, converted or edited locally, and handed back as a download — no copy is sent to a server, so there is nothing for anyone to breach or keep.
