Opera is one such browser, and it is optimized for a number of activities, among which we can also mention PDF files.

More so, the overall look and feel of Opera are extremely modern and lightweight, so it doesn’t matter if besides the PDF file you have an extra 20 tabs opened, you will not feel the RAM is all used up.

It is Chromium-based and features heavy extension support. This makes it increasingly customizable and frequently updated, making it an excellent web browser overall.
