Sam PDF Studio

Native macOS PDF editor for in-place text editing, annotation, and fill-and-sign.

Desktopfreemiumglobal

Sam PDF Studio is a free, open-source native macOS PDF editor with in-place text editing that matches the original font, annotation, fill-and-sign with saved signatures, redlining, and OCR, all processed locally on the Mac. A $30 donation is suggested but not required. It's built for Mac users who want a direct, click-to-edit PDF experience rather than a coordinate-based editing tool.
