A free, powerful, and easy-to-use app to view, annotate, sign, fill, and share PDF files from your device.

You can edit and modify PDFs with this app in order to make them easier to read, understand, and fill out.

You can also highlight, underline, and strike out text.

In addition, you can search through your PDFs to find the exact page you need, just like when you’re looking through a book.

You can also make PDFs from images and other types of files.
