In addition to viewing PDFs, the Acrobat extensions for Chrome and Edge allow them to be marked up PDFs with comments, highlights or drawings.
Filling in and e-signing forms is also supported within the browser and without requiring additional software.
There's also provision for downloading and sharing a PDF with others without sending it as an attachment.
For Acrobat subscribers, there are additional capabilities. PDF pages can be rotated, deleted or reordered; PDFs can be converted to Word documents retaining the original formatting, and web pages can be converted to PDF files that retain the original layout, formatting and links.
A seven-day free trial of the paid features is available.
The Acrobat for Chrome extension has now been rolled out in a phased manner to more than 10 million users, who have already opened more than 230 million PDFs.
The phased rollout of the Acrobat for Edge extension will begin "soon", according to the company.
