Annotate PDF FAQs
Does the file leave this device?
No. Marks are drawn locally.
Does this edit the original sentences?
No. It adds marks on top. It does not rewrite existing paragraphs. Helvetica covers Latin text; use an image stamp for other scripts.
How is this different from Watermark or Sign?
Watermark repeats across pages. Sign is a signature stamp. This page places text, one highlight, and/or one image on a page you choose.
