Files render exactly as designed, with their own styles, scripts, and interactivity. - Open HTML files from your reading folder, the file picker, or straight from the Files app - Links inside a page open in your browser, so the file you are viewing stays put - Cleaner file names for exported PDFs Plus small fixes and polish throughout.

New: Read Aloud — listen to any document with natural voices, hands-free. Choose Read Aloud from the menu, pick the speed and voice, and the page scrolls along as it reads. Plus a cleaner toolbar.

Pick up right where you left off. When you reopen a file you've been reading, tap "Jump to where you left off" to return to your last spot.
