I used php8.1 support webp (not support Avif)

[tbela99]

As suggested by the error message, the problem comes from the provided image.
I will push an update to prevent the fatal error from getting in the way, but that will not address the problem with the image palette.

[aminweb2]

i think this happen when generate webp for GIF images.

I guess you image is corrupted in some way. I will fix that as well
Thanks

[tbela99]

can you try this and let me know if your problems are solved? https://github.com/tbela99/gzip/archive/refs/heads/v.next.zip

[aminweb2]

yes, problem solved.thank you
just have an question:
how exclude an url for effect gzip plugin?
P.S:when i enabled javascript process, crash my google map!

[tbela99]

you can tell the plugin to ignore specific javascript and css. check the documentation here https://tbela99.github.io/gzip/#/./javascript?id=process-javascript

https://tbela99.github.io/gzip/#/./css?id=parse-critical-css

[tbela99]

more generally, I see that you use speedcache. I think that it is redundant, as you can already manage css with this plugin.

[tbela99]

If your problem is fixed, can you close this issue?
thanks!

[aminweb2]

in Speedcache i used just " Group CSS " and " Group JS" . if disable it , and then enabled just " Process CSS " --> make bad score in LCP and CLS . do you have any idea?

[tbela99]

You already have it covered with merge Javascript and merge CSS options:

• merge javascript https://tbela99.github.io/gzip/#/./javascript?id=merge-javascript
• merge CSS https://tbela99.github.io/gzip/#/./css?id=merge-css

[aminweb2]

Note: when i disabled Gzip plugin i achieved 85% in mobile and 97% in desktop on google pagespeed,(i attached screen)
but when enabled Gzip plugin, it is down my score in google page speed. i want achieved upper 90% in mobile.

Thankful

1. after an investigation I found that you are using JCH Optimizer. Using both plugins leads to some kind of corruption that will cause css and js files to fail to load, hence the partially loaded page. disabling JCH fixed that problem. As a rule, you should not mix multiple optimization plugins
2. GIF files are not converted, probably because they are less than 800px width. I think this is probably an issue as I would expect images to be converted regardless their size

I noticed that you use animated GIF, I am not sure whether the conversion will preserve the animation. I will probably add a feature to enable conversion for individual file types.

were you expecting GIF images to be converted?

[tbela99]

I cannot reproduce the issue. I guess, it probably happened because many extensions were trying to do the same thing.

[aminweb2]

thanks

[tbela99]

fixed!

Thank you for your contribution.
