What is the best free PDF editor for iPhone with no watermark?

RaptorPDF (browser-based, no app download needed) and Apple's built-in Markup tool in the Files app are the best free, no-watermark options for iPhone. PDF Expert also offers a free tier with no watermarks for basic annotation, though advanced features require purchase.

Why do some iPhone PDF apps add watermarks?

App developers add watermarks to free versions of their PDF editors as a way to monetize — you see 'Trial Version' or their logo stamped on output, which encourages upgrading to the paid version. Browser-based tools like RaptorPDF process files locally without needing this business model, so they can offer watermark-free output for free.

Can I annotate a PDF on iPhone for free without an app?

Yes. Open the PDF in the Files app on your iPhone, tap the Share icon, then tap Markup. You get a full annotation toolbar with pens, text, highlighter, and signature tools — completely free, no watermarks, no app download required.
