<h4>Generate WebP or AVIF</h4>
<ul>
<li>Generate WebP or AVIF file when adding image file in Media Library.</li>
<li>Generate WebP or AVIF from all the images by async/await.</li>
<li>Optionally, Can replace image files with WebP or AVIF when adding new media, and delete the original image file. Also, when generating all images, the original image file ID will be overwritten as WebP or AVIF and the original image file will be deleted. All URLs in the content are also replaced.</li>
</ul>
<h4>WP-CLI</h4>
<p>WP-CLI commands are available. If you have a large number of files, WP-CLI commands is more reliable.<br />
* <code>wp pluswebpavif</code><br />
* <code>wp pluswebpavif webp</code> -> Generated WebP.<br />
* <code>wp pluswebpavif avif</code> -> Generated AVIF.<br />
* <code>wp pluswebpavif help</code> -> Specification of this command.<br />
* <code>wp pluswebpavif webp mail</code> -> Send results via email.<br />
* <code>wp pluswebpavif webp replace</code> -> WebP or AVIF replacement of images and contents.<br />
* <code>wp pluswebpavif avif addext</code> -> Append the webp or avif extension to the original filename.<br />
* <code>wp pluswebpavif webp --pid=12152</code> -> Process only specified Media ID(Conversion source ID).<br />
* <code>wp pluswebpavif avif --quality=90</code> -> Specifies the quality of WebP or AVIF.<br />
* <code>wp pluswebpavif webp --types=image/png,image/gif</code> -> MIME type to convert.</p>

Plus WebP or AVIF

It is very useful to replace the URLs of images of existing content as well.

Easy and very useful


I really like this plugin and it's very good in other aspects. However, on both of my websites, when converting in bulk, I was unable to continue the conversion for a certain period of time, indicating an Ajax 500 error. What is the reason?


500 error


This is great plugin to save my server space!



Dear developer, I prefer to donate by paypal, usdt or stripe instead of inputting my credit card elsewhere.


Great plugin

WordPress.org

<p>This plugin adds WebP and AVIF support for media uploads within the WordPress application. By default, AVIF images will be generated if supported on the hosting server, otherwise WebP will be used as the output format. When both formats are available, the output format can be selected under <code>Settings > Media</code>. Modern images will be generated only for new uploads, pre-existing images will only converted to a modern format if images are regenerated. Images can be regenerated with a plugin like <a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="ugc">Regenerate Thumbnails</a> or via WP-CLI with the <code>wp media regenerate</code> <a href="https://developer.wordpress.org/cli/commands/media/regenerate/" rel="nofollow ugc">command</a>.</p>
<p>By default, only modern image format sub-sizes will be generated for JPEG or PNG uploads – only the original uploaded file will still exist as a JPEG/PNG image, generated image sizes will be WebP or AVIF files. To change this behavior, there is a checkbox in <code>Settings > Media</code> “Output fallback images” that – when checked – will result in the plugin generating both the original format as well as WebP or AVIF images for every sub-size (noting again that this will only affect newly uploaded images, i.e. after making said change).</p>
<p><em>This plugin was formerly known as WebP Uploads.</em></p>


Modern Image Formats


I love that it doesn't force you to generate all image sizes of the original format and avif, but just does the avif (or webp if you choose that). It would be really nice if it could rework old images, and maybe even modify the database to match. But still, excellent and should be installed first thing on all new WP sites in my opinion.


Easiest way to get AVIF images


Thanks for developing this plugin!It's my #1 plugin for image optimization!


So far so good!

Converts images to more modern formats such as WebP or AVIF during upload.
