Convert images to Webp
======================

[](#convert-images-to-webp)

What does it do?
----------------

[](#what-does-it-do)

The extension copies and converts all png and jpg images in the fileadmin/*processed* folder to the webp format. Browser which could read webp images load the webp images instead of the jpg or png files. The webp images are generated when new processed images in jpg or png format are added in the *processed* folder.

***Important***

Every jpg or png image is stored as webp file a second time in the folder (bigger storage size).

Installation
------------

[](#installation)

Simply install the extension with Extension Manager or Composer `composer require svenjuergens/cs-webp`Clear the processed images in the install-tool and reload the Backend. Add the code in the head of your root .htaccess file. This .htaccess Code rewrites the jpg and png images to the webp files if webp is readable in the browser. Change the level of quality if needed in the extension configuration in extension manager (default 65)

```

        RewriteEngine On
        RewriteCond %{HTTP_ACCEPT} image/webp
        RewriteCond %{DOCUMENT_ROOT}/$1.webp -f
        RewriteRule ^(fileadmin/_processed_.+)\.(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1]

        Header append Vary Accept env=REDIRECT_accept

    AddType image/webp .webp

```
