What sets it apart

Built for the result.

Real annotations

Highlights and notes are PDF annotations: your readers find them in the comments panel of their software, and can reply to them.

02

Text stays text

Annotating does not touch the document: highlighted text stays selectable and searchable, and annotations can be removed one by one.

Accepted formats

Drop them as they are, no conversion needed first.

Where your files are processed

With this tool, your file is not transmitted anywhere: not to us, not to any third party. We know neither its name, nor its contents, nor its size.

Nothing is kept, because nothing reaches us.

Frequently asked

What people ask us.

Another question? The contact address is at the bottom of the page.

Yes. Highlights, underlines, strike-outs and notes are saved as standard PDF annotations, read by Acrobat, Preview, Edge, Chrome and other readers.
