You can go right to Google and build the WebP libraries from source. Use this link to get the appropriate archive for your operating system:

https://developers.google.com/speed/webp/docs/compiling#building

Then you can use the following command within a php system() function to convert the images:

Syntax:

  cwebp [quality 
 qualitypercentage] [source 
 image] -o [destination]`

 cwebp -q 80 source.png -o 
 destination.webp

I would recommend reading the above link to get your libraries compiled, then go here to get more information about using the libraries.

Best of luck with the project!

You can use Intervention Image Library. It provides various image encoding options and utilities related to image formatting. Here is the sample code snippet to convert image into webp format. It supports numerous image encodings as listed below,

• jpg — return JPEG encoded image data
• png — return Portable Network Graphics (PNG) encoded image data
• gif — return Graphics Interchange Format (GIF) encoded image data
• tif — return Tagged Image File Format(TIFF) encoded image data
• bmp — return Bitmap (BMP) encoded image data
• ico — return ICO encoded image data
• psd — return Photoshop Document (PSD) encoded image data
• webp — return WebP encoded image
• data data-url — encode current image data in data URI scheme (RFC 2397)

Answer 5

The options currently available are: gd (extension), imagick (extension), imagick (exec-call), gmagick (extension), gmagick (exec-call), cwebp (exec-call), gmagick (exec call) or calling a cloud service. I have created a library 'webp-convert' on github which tries all methods. The readme-file describes the pros and cons of each method. Its available here: https://github.com/rosell-dk/webp-convert.

For reasons unknown to me, the imagick/gmagick extensions produces no better quality than the original files. This is only a problem with the extensions, not the exec calls.
