<h4>Generate WebP or AVIF</h4>
<ul>

<li>Generate WebP or AVIF from all the images by async/await.</li>

</ul>

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.

<p>Image Format Converter is a powerful, lightweight administrative tool that allows you to easily convert images in your WordPress Media Library to modern formats like WebP and AVIF, as well as standard PNG and JPG formats.</p>
<p>By leveraging your server’s native PHP image processing libraries (GD or Imagick), this plugin converts images with high quality and optimal compression. With the newly added AJAX-powered engine, you can now select and convert multiple images at once, watch their progress in real-time with an animated progress bar, and see exactly how many kilobytes and storage percentage you saved.</p>
<p><strong>Features:</strong><br />
* <strong>AJAX Bulk Conversion:</strong> Select multiple images from the Media Library and convert them sequentially. Prevents script timeouts on large libraries.<br />
* <strong>Proportional Resizing:</strong> Set optional maximum width or height constraints to scale down high-resolution images during conversion.<br />
* <strong>Media Library Row Action:</strong> Convert images directly from the Media Library list view (<code>upload.php</code>) with a quick “Convert Format” link.<br />
* <strong>Size Savings Calculator:</strong> Shows original size, converted size, and total storage savings in real-time.<br />
* <strong>Metadata Control (EXIF Stripping):</strong> Clean up extra file space by stripping camera EXIF profiles and color data when using Imagick.<br />
* <strong>Auto-Delete Original:</strong> Clean up your server automatically by deleting the original image file and database attachment after a successful conversion.<br />
* <strong>Flexible settings:</strong> Configure JPEG quality, PNG compression levels, WebP/AVIF quality, and toggle Media Library registration.<br />
* <strong>Server Diagnostics:</strong> View library status (GD, Imagick, WebP, AVIF) at a glance, with step-by-step instructions to enable missing libraries.</p>
<p>Access all features by going to <strong>Media > Image Converter</strong>.</p>
