webp is only an improvement when you only consider web.
What was the issue with JPEGs, GIFs, PNGs and SVGs? You have one distinct format for Photos, one for animated graphics, one for loseless graphics and one for scalable illustrations.
Now come WebP designed and devloped by Google to bring a revolution to image formats while ignoring Vector Graphics? What about People work with Imagery, that format doesn't help them at all.
The only benefit I see is WebP for animations as it isnt limited to a 256 indexed colourpalette.
Not really.
JPEG is a lossy compression format. It loses information to reduce filesize.
PNG is a lossless compressed format. It serves as a well-rounded format for general purpose image compression without the loss of information. The downside is the image can be much large in file size.
SVG is a vector graphic, as you seem to be aware. These files have what is effectively infinite resolution, but can be significantly larger in filesize, depending on the circumstances.
WEBP is a more efficient lossless compression format. It is analogous to PNG, but smaller file size. Additionally, as you stated, it can also be used for animated graphics,like GIF formats.
I think WEBP is a decent format and is significantly more modern than PNG. That being said, however, the main issue is the lack of modern integration and adaptation for newer image formats.
Personally, I use whatever. The only exception is when 8 need to store images on github in a repository. Then, I will typically convert to webp and optimise the image to reduce the file size as much as possible.
yes JPEG is lossy since it has great a great artifcating solution to keep the photo as close to its original state while reducing its filesize.
WebP also supports a lossy format.
Yeah, JPEG uses a convolution to effectively average the values. I think there are other ways, though I cannot remember the context or file format, which use some interesting concepts from linear algebra. I recall a professor telling me about using singular value decomposition in the process. But that's a different topic.
I didn't know WEBP also supports lossy compression. That makes it even more flexible.
Webp is there to replace jpegs, gifs, and smaller pngs. It's better than them in mostly everything, it took around 10 years for something slightly better to come (jxl), and it ran into the same issue, the lack of support from some big asshole company
Mhm given that the adoption of WebP after 15 Years isn't fully there and PNG/JPG/GIF are still majorly used fileformats... I guess you are right. Yet still, WebP is more like an export format than a general use format.
