PDF review that travels.
Mark up a document with sticky-note comments, highlights, strikeouts, ink, and shapes. Every annotation is written into the PDF itself — so your review opens intact in Acrobat, Preview, or any other reader, no RedLine required.
RedLine runs in your browser. Your documents are processed transiently to apply your edits and are not stored on our servers. Annotation review states (status, assignee, notes) stay on your device.
When you connect a Google account, RedLine accesses only the files you select — never your full Drive. Details in the privacy policy.
