When you have installed plugin and converted all images, follow these steps:

Run Google Chrome and enable Dev Tools (F12). Go to the Network tab click on Disable cache and select filtering for Img (Images). Refresh your website page. Check list of loaded images. Note Type column. If value of avif is there, then everything works fine. NGiNX and Apache together If you have some proxy setup or some other combination of NGiNX and Apache on your server, then probably .htaccess changes won't work and you will need to ask your hosting provider to disable NGiNX direct processing of image static files. Apache .htaccess Plugin should automatically update your .htaccess with needed rules. In case it's not possible to write them automatically, screen with instructions will appear. Anyway, here is how it should look like: AddType image/avif .avif RewriteEngine On RewriteCond %{HTTP_ACCEPT} image/avif RewriteCond %{REQUEST_FILENAME} "/" RewriteCond %{REQUEST_FILENAME} ".(jpg|jpeg|png|gif|webp)$" RewriteCond %{REQUEST_FILENAME}.avif -f RewriteCond %{QUERY_STRING} !no_avif RewriteRule ^(.+)$ $1.avif [NC,T=image/avif,E=avif,L] NGiNX config After you activate plugin, screen with instructions will appear. Anyway, here is how it should look like: You need to add this map directive to your http config, usually nginx.conf ( inside of the http{} section ): map $arg_no_avif $no_avif{ default ""; "1" "no_avif"; } map $http_accept $avif_suffix{ default ""; "~*avif" ".avif"; } then you need to add this to your server block, usually site.conf or /nginx/sites-enabled/default ( inside of the server{} section ): location ~* ^/.+.(png|gif|webp|jpe?g)$ { add_header Vary Accept; try_files $uri$avif_suffix$no_avif $uri =404; }

Frequently Asked Questions

Common questions about Images to AVIF

Just add ?no_avif=1 to the URL and original JPG/PNG will be loaded

Run Google Chrome and enable Dev Tools (F12). Go to the Network tab click on Disable cache and select filtering for Img (Images). Refresh your website page. Check list of loaded images. Note Type column. If value of avif is there, then everything works fine. NGiNX and Apache together If you have some proxy setup or some other combination of NGiNX and Apache on your server, then probably .htaccess changes won't work and you will need to ask your hosting provider to disable NGiNX direct processing of image static files. Apache .htaccess Plugin should automatically update your .htaccess with needed rules. In case it's not possible to write them automatically, screen with instructions will appear. Anyway, here is how it should look like: <IfModule mod_mime.c> AddType image/avif .avif </IfModule> <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_ACCEPT} image/avif RewriteCond %{REQUEST_FILENAME} "/" RewriteCond %{REQUEST_FILENAME} "\.(jpg|jpeg|png|gif|webp)$" RewriteCond %{REQUEST_FILENAME}\.avif -f RewriteCond %{QUERY_STRING} !no_avif RewriteRule ^(.+)$ $1\.avif [NC,T=image/avif,E=avif,L] </IfModule> NGiNX config After you activate plugin, screen with instructions will appear. Anyway, here is how it should look like: You need to add this map directive to your http config, usually nginx.conf ( inside of the http{} section ): map $arg_no_avif $no_avif{ default ""; "1" "no_avif"; } map $http_accept $avif_suffix{ default ""; "~*avif" ".avif"; } then you need to add this to your server block, usually site.conf or /nginx/sites-enabled/default ( inside of the server{} section ): location ~* ^/.+\.(png|gif|webp|jpe?g)$ { add_header Vary Accept; try_files $uri$avif_suffix$no_avif $uri =404; }

Delete all generated AVIF images There is no button to do that and it will also not delete generated AVIFs automatically when you deactivate the plugin, but if you really need this, you can run some shell command to achieve this: find . -type f -name "*.avif" -exec bash -c 'if [ -f "${1%.avif}" ]; then echo "Deleting $1"; rm "$1"; fi' _ {} \; This will find all the files with a .avif extension and if there is similar file with the exact filename, but without the .avif extension, then it will delete it.
