Canva

Canva is the answer for those who need to design something quickly and throw something together without a hassle. It is extremely easy to use and design a variety of things, be it brochures, logos, images or even business cards. Unlike other graphic design programs out there, this one requires very little learning - which makes it a winner in my book. It's beauty lies in stripping all the complex tools and instructions to making something even a child in kindergarten can use.

Canva is very useful for creating quick creations I would not use it as my primary but very useful I would recommend it for people that don't know how to use Photoshop or gimp. Very quick and easy design

Pros:
Easy to use design
Upload images and keeps the images for next time
Supports PNG,JPG,etc
Download in PNG,JPG and PDF
Premade Templates and Layouts
Fast Design

Cons:
Server can sometimes crash and the edits that are not saved will be lost
You have to pay for Canva's Stock photos unless you want a watermark
Some features not available in the free version

I can get more information about doing presentations.

I like Canva because it is fairly simple to use. But, it is a bit limited too and I don't like that some of the free features were taken out.

Another "web app" that can't perform even a single task without making an account, or of course giving them one of your personal accounts from another site like google.

This is not appropriate, private or secure.
