* Hi,
I am integrating avif images using picture tag. The only place on my website
that doesn’t use avif images is CRP. Is there a filter for html img tag does
I could use to inject picture tag around it? I have googled for a list of CRP
filters but couldn’t easily find it. Thank you in advance for your answer.

* Huh, I had to spend almost an hour before I found crp_get_image_html and I am
going to use it 🙂
So I am closing this ticket in order not to bother the author
🙂

* Sorry for the delay. Glad to know you found it. Am curious as to what code you’re
using to add the avif support

* I am using go-avif ([https://github.com/Kagami/go-avif/](https://github.com/Kagami/go-avif/)),
but I am looking for something else as it is huge memory requirements – a 1MB
JPG may take like 4-6 GB of RAM to convert.
And around it my dirty code around
some hooks. The only issue I have is the WP editor: [https://core.trac.wordpress.org/ticket/51417](https://core.trac.wordpress.org/ticket/51417)

* Well, the JPG standard is in retreat. I have put on my website one test image
with picture tag presenting three images – avif, webp and jpg fallback.
The
data for today:
* JPG: 177
WEBP: 697 AVIF: 213
* So old good JPG is the last. WEBP currently leads because of mobile Chrome (not
everyone has updated yet) and Firefox which supports AVIF but it is disabled
by default in the config.
* Most of images I have in AVIF and JPG and I graph their numbers. The average
for last 36 hours is 27 JPG’s and 9 AVIF in a unit of time.
When most mobile
devices will have new Chrome and Firefox will enable AVIF by default then AVIF
numbers should be higher than JPG. And files are at least 30% smaller.

* that’s pretty good. What are you using to generate the webp and avif’s? I’m quite
reluctant to pay for solutions at least at this stage for my personal blogs.

* The webp’s are easy – php has a built-in function to deal with it. But I used
the plugin media webp: [https://wordpress.org/plugins/media-webp/](https://wordpress.org/plugins/media-webp/)
It is old, not maintained and has one annoying bug, but it is very efficient.
I however don’t create any webp files for new images, but I keep them for images
added earlier.
* I do avif’s with go-avif ([https://github.com/Kagami/go-avif/](https://github.com/Kagami/go-avif/))–
it is a CLI tool for Linux x64. The only issue is its huge RAM requirements.

* Thank you for this. I can see that avif is better which I understand as your
approach.
* I noticed that [https://wordpress.org/plugins/imagify/](https://wordpress.org/plugins/imagify/)
is good for freely converting to webp and might give that a spin. My sites barely
have any visitors so the performance optimisation might take me more time to
do vs the slightly faster/incremental visitor count 🙂

* As far as I see that imagify sends your pictures somewhere to be optimized there.
I don’t like it and all my plugins do local optimization. But well, if you don’t
have shell access to the server then I guess it is easier.
