PDF tools for a cup of coffee (or free) on chromebooks

Do you still remember the times when you had to buy expensive software just to get small things done? E.g. Acrobat software of Adobe just to manipulate pdfs? Do you remember that operating systems and computers were expensive? This time is definitely over.

With a chromebook and a cool cloud tool you can manipulate pdfs as well. Have a look at smallpdf.com. The best tool I found to manipulate pdfs in many different ways.
Do not forget to donate a coffee for the programmers!

Update: Google Music upload from chromebooks

So far there was no way to upload music from a google computer (chromebook) to google music. Which was somehow odd.

Text below is obsolete now. Google music is now supporting uploads from chromebook (even from the gdrive). Thanks to the developers. More details at google plus post here.

Now, at least a lab version of the upload exists. So, there is no download (upload) manager needed anymore (which was until not recently compatible to chromebook, only windows, mac, linux was supported).

Here is a step by step tutorial for you.
