Better explain image compression #118

Closed lmuzquiz closed 5 years ago

I think the 80% quality image optimization explanation is ambiguos. Clarification needs to be made. Does the image is compressed 80% (100kb x .2 = 20kb) or does the uploaded image will have 80% of the original quality? (100kb x .8 = 80kb).

Please include a detailed description of your changes and provide before/after screenshots if applicable

Sorry but this isn't at all accurate. 80% quality = file is compressed to around 80% of its original quality.

It is in no way synonymous with a 80% of compression, and 80% compression also does not mean an 80% reduction in filesize. Those are all completely different things.

"80% quality" is the correct description for the type of compression happening here, and is well understood by most people.
