WebP Images Generator for Osclass

WebP Images Plugin simply takes every listing image on your classifieds and create it's ".webp" version.

This conversion works for JPG, JPEG, PNG and GIF listing images. Admin can select:

• Quality of WebP images (0 - 100)
• Engine used to generate WebP images (GD library by default - imagewebp function must exists, or ImageMagick if available)
• Type of images for those WebP format will be generated (thumbnail, preview, normal sizes)

Installation and setup

Initial installation is super easy. Once you've installed plugin, go to Configuration page of plugin, select quality, types of images, ... and save.

• New listings - WebP images are automatically generated on publish
• Existing listings - go to Settings > Media and simply regenerate your thumbnails. As this may be extensive process on large classifieds, we recommend to use latest version of Osclass that allows sequential images regeneration.

Plugin also allows to modify image URLs without need to modify single line of code. You can automatically replace:

• thumbnail images
• preview images
• normal images

How it works? Plugin use "filter" for resource URLs and change extension. Using only WebP images in theory may cause problems to customers using legacy/old browsers.

Advanced integration for legacy browsers

In order to provide full support to legacy browsers, plugin contains functions those generates new HTML tags using "picture" and "srcset".

<?php echo wbp_thumbnail_resource_tag()); ?>

Alternativelly, it is possible to use only functions to get ".webp" image url:

<?php echo wbp_replace_extension($link); ?>

What is WebP image and its benefits

WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.

WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.

Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing 3× smaller file sizes compared to PNG.
