Which file types does Optimize Scanned PDF 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 Optimize Scanned PDF?

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.

Is it safe to use for a document with personal details in it?

That is the design goal: the document stays on your device, so a statement, a contract or an ID photo is never transmitted for processing. Nothing here needs an internet connection once the page has loaded, apart from engines that fetch their own model data.
