For the past few years when I have needed to share my presentations online I have been using Slideshare.
There were two key reasons for this; firstly it allowed people to view the presentation within a webpage, without needing to download it and open Powerpoint and where appropriate in context. Secondly, I generally use Apple’s Keynote for my presentations. Most people don’t have Keynote (you need a Mac) and because of my style of presentation most of the presentations were too big for downloading, usually in the region of 100-200MB. I liked Slideshare as I could then embed my presentation into my blog and also into other webpages and sometimes the VLE. You can read about my presentation workflow here.
However in April, Slideshare brought in a 10MB limit on uploads for free accounts. Not wanting to spend £19 a month on a service I probably use once a month, I asked on the Twitter and Google+ for solutions.
Doug Belshaw said to save as PDF and use ColorSync Utility (part of Mac OS X) to reduce the file size. This I did and I did managed to reduce my presentation to an 11MB PDF, which alas was still too big for Slideshare. However this was certainly a useful tip for sharing other PDFs by email for example.
Two people on the twitter, @hjames and @sboneham both recommended Speakerdeck to me. So that’s what I did and went and had a look. I actually found I already had an account and had tried it out once, but didn’t use it again. I suspect I tried it, found it didn’t add anything at that time over Slideshare and then didn’t go back!
You upload your presentation as a PDF and the service will convert it into an online presentation that people can click through slide by slide (in a similar manner to Slideshare).
The process was pretty straightforward and in many ways I much prefer the look and feel of Speakerdeck compared to Slideshare.
Speakerdeck works well on iOS devices too, which is useful. As well as sharing by link you can also use an embed code to add your Speakerdeck presentation to a blog, web page or a VLE. As a result I have placed most of my recent presentations on Speakerdeck.
When writing this blog post I wanted to check a few things and have found that Slideshare have relented on their 10MB limit and have raised it to 100MB. So will I go back to Slideshare…. hmm not sure.
