During compression file size increases

[s5unanow]

I've tried to compress file

But instead of compressing, pixo increased file size

Yes I have another example

Pretty dramatic increase in my case

Here is the original picture:

I think the issue with that first file is that it's a jpg instead of a png. If you rename:

The second image mentioned is already compressed! So makes sense there isn't much more we can do there versus the best compression tools. I think it would be nice if the UI told you the file was compressed, I'll think about this 😄

I think it would be nice if the quality slider turned red or yellow until it's slid low enough for the re-compressed image to be smaller, but still let you choose a higher quality at least for experimentation, and showed a very short message with a "more" link to see more details. The extra detail could be short, or it could have the added suggestion of scaling the image down as well. Or it could be a link that opens in a new window to a deep link in the docs.
