WEBP

[Xn User]

Hi )
I can not understand why in WEBP quality 100% does not mean lossless quality, but select lossless quality means lossless quality, why this so?

I select quality, and there not said what I select only lossy mode, because I think what this misleads )

I offer rename mode quality to lossy mode )

Tested in XnView MP 1.93 )

it works like that in libwebp

Maybe , but then need modify value Quality to Lossy quality , I think what if this do, users will more clear )

I guess the WEBP developers use the same settings like JPEG,
set JPEG encoder to 100% quality means lossy compression, too.

The only difference is that WEBP has an additional lossless compression algorithm, which JPEG has not.

It might be confusing to users that a 100% setting doesn't mean lossless but highest lossy quality instead.
