Rewrite image to webP not working

Hello,

I use the rewrite mode to have my jpg|png|gif etc…. images loaded in webp.

Unfortunately when I go to network and inspect the page I can see that it doesn’t work and the images are still loaded in their original format.

I don’t use a CDN and the webp images exist.

Here’s what’s been added to the htaccess :

# BEGIN Imagify: rewrite rules for avif
<IfModule mod_setenvif.c>
	# Vary: Accept for all the requests to jpeg, png, and gif.
	SetEnvIf Request_URI "\.(jpg|jpeg|jpe|png|gif|webp)$" REQUEST_image
</IfModule>

<IfModule mod_rewrite.c>
	RewriteEngine On
	RewriteBase /

	# Check if browser supports AVIF images.
	# Update the MIME type accordingly.
	RewriteCond %{HTTP_ACCEPT} image/avif

	# Check if AVIF replacement image exists.
	RewriteCond %{REQUEST_FILENAME}.avif -f

	# Serve AVIF image instead.
	RewriteRule (.+)\.(jpg|jpeg|jpe|png|gif|webp)$ $1.$2.avif [T=image/avif,NC]
</IfModule>

<IfModule mod_headers.c>
	# Update the MIME type accordingly.
	Header append Vary Accept env=REQUEST_image
</IfModule>
# END Imagify: rewrite rules for avif

# BEGIN Imagify: rewrite rules for webp
<IfModule mod_setenvif.c>
	# Vary: Accept for all the requests to jpeg, png, and gif.
	SetEnvIf Request_URI "\.(jpg|jpeg|jpe|png|gif)$" REQUEST_image
</IfModule>

<IfModule mod_rewrite.c>
	RewriteEngine On
	RewriteBase /

	# Check if browser supports WebP images.
	RewriteCond %{HTTP_ACCEPT} image/webp

	# Check if WebP replacement image exists.
	RewriteCond %{REQUEST_FILENAME}.webp -f

	# Serve WebP image instead.
	RewriteRule (.+)\.(jpg|jpeg|jpe|png|gif)$ $1.$2.webp [T=image/webp,NC]
</IfModule>

<IfModule mod_headers.c>
	Header append Vary Accept env=REQUEST_image
</IfModule>
# END Imagify: rewrite rules for webp

Can you tell me what’s wrong?

Thanks in advance, I’ve tried everything.
