WebP support in Storyline to lower carbon footprint of training

Great feature ask, and I would welcome WebP support in Articulate too as more clients are adopting this new format. I believe you can request features officially here.

Thanks Brian. I;ve put a request in.

I am a web developer as well as a Storyline user, and I've just had to NOT use Storyline for a project as the client (who has quite environmental concerns) wanted any imagery used to be something more eco-friendly than jpg and png. I have had to build this project using HTML and PHP directly, which is a shame.

For the record, using webp image formats rather than jpg and png can leading to file size savings of over 50%.

I just ran a search for avif images on the Articulate forums and there's not one mention of the topic on here.

Avif is a file format similar to webp in that it can lead to really impressively low file sizes with equitable lossiness as jpg/png, but isn't _quite_ as popular/supported as webp at the moment.

Here are the browser support results for both formats:

Using compression techniques like in TinyPNG ( https://tinypng.com/ ) compresses any files 2 to 4 times...so for sure as good a compression as WebP. If WebP and WebM are a must then maybe Lectora will fit the bill as with that you now can directly import and use WebP and WebM files. WebM for sure is really great as that will allow for transparant movies.

TinyPNG is certainly good, and for an automated tool it's brilliant.

I found I could shave some more off PNGs when using PhotoShop's webp WebPShop plugin (sadly no native support for webp in PhotoShop as yet, but the plugin is pretty good).

A simple comparison of a normal then a transparent image saved as webp in PhotoShop then via TinyPNG yielded savings of ~10% to 20%.

YMMV.

Be interesting to see how it fared against different images.
