Sumatra PDF 2.4

Sumatra PDF is a free PDF, eBook (MOBI), XPS, DjVu, CHM, Comic Book (CBZ and CBR) reader for Windows. Sumatra PDF is small and starts up very fast. Simplicity of the user interface has a high priority. Portable version included (a single executable that can be run e.g. from USB drive and doesn't write to registry).

What's new in version 2.4:

  • full-screen mode for ebooks (Ctrl-L)
  • new key bindings:
  • F9 - show/hide menu (not remembered after quitting)
  • F8 - show/hide toolbar
  • support WebP images (standalone and in comic books)
  • support for RAR5 compressed comic books
  • fixed multiple crashes

no links to the 64bit version?

because when the program prior to this build directed to the site it's links are dead but it did have a 64bit build there but with this current build when you go to the website through the program itself it don't seem to have any links to 64bit builds.

PDF X-change viewer is my preferred Acrobat alternative, largely due to the speed, rendering quality, and strong mark-up functions.

However, this open-source viewer is really coming on in leaps and bounds - for simple PDF viewing, it's unbeatable.

Just noted "Inside Macintosh" (in the screenshot)!

The only issue I've had with Sumatra PDF is when I have 10+ PDFs open at a time (rendering while scrolling goes funny). I'm willing to test this out to see if it's been fixed.

"Simply" the best.

Who in the world would have 10 pdf's open, and why, at the same time? Of course that's going to scroll funny! I'd bet ANY pdf reader, on ANY machine, would act that way then!

any would behave that way. Even adobe reader. Maybe a science geek might have 10 pdf's open at any given time.

I love this little reader. Tiny but supports loads of formats. Is super fast to both start up and render the documents. I have not had any rendering issues that I have seen others mention in the past. I would hate to have to go back to Adobe Reader now. Such a solid little app. If you have to work with a lot of PDF files this little program will be a god send for you as it was me!

To many other pdf readers out there to even think about going back to that crapware Adobe!

This one is a great one though.


Define crapware plz.
