The PDF app that feels native — read, annotate, edit text and images, fill and sign forms, and redact, all at a speed the incumbents never manage.

PDF Expert opens big documents instantly and lets you actually work on them: change the words in a paragraph, swap an image, rearrange pages, fill in a form, add a signature, or permanently redact a block of text. It reads like a document viewer and edits like a proper tool.
Readdle has spent years making PDF Expert feel like it ships with macOS — fluid scrolling, a clean toolbar, sensible defaults — while quietly covering nearly everything you would otherwise open Acrobat for. It is the rare productivity app in this space that people describe as pleasant.
