What's new in PDF Colophon

Colophon is on the App Store. This page tracks what changes from version to version. Here's what the first release brings.

Version 1.0: the first release

The first release brings the full document studio together on iPhone, iPad, and Mac, entirely on-device: in-place text and image editing with object copy and paste, true redaction, and page organization — reorder, rotate, crop, combine documents, Bates-number them, and resize pages to a standard paper size.

Marking up runs deep: highlight, underline, and strikeout that snap to the text; rectangles, ellipses, lines, arrows, comments, text boxes, and callouts; and pressure-sensitive freehand ink. You can find and replace text on the page, print, fill and flatten forms and export their data as XFDF, and pull every annotation into a Markdown summary.

Security covers drawn and cryptographic signatures with trusted RFC 3161 timestamping, signature verification, password protection, and removing a password again. Scanning captures paper straight to searchable PDF with automatic OCR. On-device Apple Intelligence chats over your documents and library with page-cited answers, full-content search reaches every document, and Colophon plugs into the system through Spotlight, Shortcuts, and Siri. On the Mac it's a real Mac app, with a native menu bar and the full keyboard-shortcut set.
