convert_to_webp_animated don't work while convert_jpeg_to_webp is disabled.

Hello,

I disable convert_jpeg_to_webp and seems convert_to_webp_animated also don't work. Here is filter settings in my pagespeed.conf file:

# Filter settings

I want to convert animated GIF to animated WebP while convert_jpeg_to_webp is disabled. Please tell me what config should I use?

Thanks,

Hi,

Animated GIFs are usually large and take relative longer time to optimize. When you check the result, please give your server a little more time.

convert_to_webp_animated and convert_jpeg_to_webp are independent operations: one only applies to animated GIF while the other only applies to JPEG. You should be able turn on either of them without affecting the other.

Your conf file has some redundant settings:

- "recompress_images" is a filter group which includes convert_jpeg_to_webp etc.

- "rewrite_images" is another filter group which includes all filters in recompress_images and others.

- Rewrite level "CoreFilters" includes "rewrite_images".

Details of the filter groups and rewrite level are in https://developers.google.com/speed/pagespeed/module/filter-image-optimize and https://developers.google.com/speed/pagespeed/module/reference-image-optimize

You can remove "recompress_images" and "rewrite_images" from the conf file, but keep these two lines:

pagespeed DisableFilters convert_jpeg_to_webp;

pagespeed EnableFilters convert_to_webp_animated;

If you still have the problem, please let us know. Including a link to your website would be helpful for us to debug.
