Everyone loves SumatraPDF

SumatraPDF is one of those amazing open source programs that does everything a closed-source and/or commercial product does, but better in every way.

"PDF readers have, over the years, managed to earn themselves something of a reputation for being slow, lumbering beasts – thanks largely to Adobe Reader. Sumatra PDF bucks the trend. It is small, svelte, lightweight and lightning fast."

I was tired of using slow loading & bloated Adobe pdf-reader.
I found SumatraPDF. I'm happily using the portable application.
Thanks to its simple user interface, small memory footprint & fast startup.

The best PDF reader I have used since I started reading PDFs in 1998 is SumatraPDF.

Lightweight, fast loading, minimal resource hogging.

SumatraPDF v3.4 is the bomb! What a great piece of software by @kjk . The custom-keybindings work like a charm!

I like SumatraPDF. Runs the circles in terms of performance around the sad piece of crap that Adobe PDF Reader has become.

If your Adobe reader croaks or feels glitchy while scrolling, try Sumatra PDF instead. It will be almost like opening a plain text document. Plus you can easily highlight text.

I love Sumatra PDF, thank you for making it.

I won't need to buy a PDF reader ever again, now that I have SumatraPDF

I'm a big fan of SumatraPDF and use it everywhere I can.

I am pretty happy with SumatraPDF on Windows. Orders of magnitude faster than Reader too.

Sumatra PDF is the best.

I like Sumatra PDF. It's speedy, lightweight, and gets the job done.

I used to use Foxit, but have since turned to SumatraPDF. It seems to be a little lighter weight than Foxit.
