Title: Modern Image Formats Author: WordPress Performance Team Published: ഏപ്രിൽ 6, 2023 Last modified: ജനുവരി 9, 2026 --- Search plugins ![](https://ps.w.org/webp-uploads/assets/banner-772x250.png?rev=3098226) ![](https://ps.w.org/webp-uploads/assets/icon.svg?rev=3098226) # Modern Image Formats By [WordPress Performance Team](https://profiles.wordpress.org/performanceteam/) [Download](https://downloads.wordpress.org/plugin/webp-uploads.2.6.1.zip) * [Details](https://ml.wordpress.org/plugins/webp-uploads/#description) * [Reviews](https://ml.wordpress.org/plugins/webp-uploads/#reviews) * [Installation](https://ml.wordpress.org/plugins/webp-uploads/#installation) * [Development](https://ml.wordpress.org/plugins/webp-uploads/#developers) [Support](https://wordpress.org/support/plugin/webp-uploads/) ## Description 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 `Settings > Media`. 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 [Regenerate Thumbnails](https://wordpress.org/plugins/regenerate-thumbnails/) or via WP-CLI with the `wp media regenerate` [command](https://developer.wordpress.org/cli/commands/media/regenerate/). 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 `Settings > Media` “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). _This plugin was formerly known as WebP Uploads._ ## Installation #### Installation from within WordPress 1. Visit **Plugins > Add New**. 2. Search for **Modern Image Formats**. 3. Install and activate the **Modern Image Formats** plugin. #### Manual installation 1. Upload the entire `webp-uploads` folder to the `/wp-content/plugins/` directory. 2. Visit **Plugins**. 3. Activate the **Modern Image Formats** plugin. #### After activation 1. Visit the **Settings > Media** admin screen. 2. Use the controls in the **Modern Image Formats** section to configure modern image formats. ## FAQ ### Where can I submit my plugin feedback? Feedback is encouraged and much appreciated, especially since this plugin may contain future WordPress core features. If you have suggestions or requests for new features, you can [submit them as an issue in the WordPress Performance Team’s GitHub repository](https://github.com/WordPress/performance/issues/new/choose). If you need help with troubleshooting or have a question about the plugin, please [create a new topic on our support forum](https://wordpress.org/support/plugin/webp-uploads/#new-topic-0). ### Where can I report security bugs? The Performance team and WordPress community take security bugs seriously. We appreciate your efforts to responsibly disclose your findings, and will make every effort to acknowledge your contributions. To report a security issue, please visit the [WordPress HackerOne](https://hackerone.com/wordpress) program. ### How can I contribute to the plugin? Contributions are always welcome! Learn more about how to get involved in the [Core Performance Team Handbook](https://make.wordpress.org/performance/handbook/get-involved/). ### I’ve activated the Modern Image Formats plugin, but WebP images are not always generated when I upload a JPEG image. Why? There are two primary reasons that a WebP image may not be generated: 1. The Modern Image Formats plugin has identified that the WebP version of the uploaded JPEG image would have a larger file size than the original JPEG image, so it does not generate the WebP version. 2. The JPEG image was not uploaded to the [Media Library](https://wordpress.com/support/media/). At this time, WebP versions are only generated for images to the Media Library. WebP versions are not generated for JPEG images that are added to your site in other ways, such as in a template file or the [Customizer](https://wordpress.com/support/customizer/). ### With the Modern Image Formats plugin activated, will the plugin generate JPEG and WebP versions of every image that I upload? By default, the Modern Image Formats plugin will only generate WebP versions of the images that you upload. If you wish to have both WebP **and** JPEG versions generated, you can navigate to **Settings > Media** and enable the **Generate JPEG files in addition to WebP** option. ## Reviews ![](https://secure.gravatar.com/avatar/80e914c33cfcb58bb025742ce294e1d12f214079d7e14ac31b35e24477c06eda? s=60&d=retro&r=g) ### 󠀁[Funktioniert wie beschrieben – Heimvorteil weil von WordPress entwickelt](https://wordpress.org/support/topic/funktioniert-wie-beschrieben-heimvorteil-weil-von-wordpress-entwickelt/)󠁿 [lacoste89](https://profiles.wordpress.org/lacoste89/) മാർച്ച്‌ 22, 2026 Ich nutze dieses Plugin auf allen neuen Webseiten, damit Bilder automatisch nach AVIF konvertiert werden.

The plugin needs to warn users that once youve regenerated post thumbnails and complete entire process is complete even if you deactivate the plugin wordpress will would force you to use tha Avif or webp version of your images. in which a lot of cases will break site. And one would think you can reverse nope that is not case. I had to result to using a back up data base to restore content. I have about 10K images that includes is variable sizes and variable formats on 2 websites . I Have ZERO plans to figure out which is a jpg and png on those let alone re attach them. There is no official wordpress to manually restore them. This plugin needs to be further improved. ![](https://secure.gravatar.com/avatar/222ae0c7209b2c1624b3560bd96c1d68900cdfcfd41495610c5da40ab7447079? s=60&d=retro&r=g) ### 󠀁[Good one](https://wordpress.org/support/topic/good-one-623/)󠁿 [nmask](https://profiles.wordpress.org/nmask/) സെപ്റ്റംബർ 2, 2025 Nice light plugin, does what is says. ![](https://secure.gravatar.com/avatar/488fa9427cd9420d96a8a423f6186e0ab7c14865020ae2432ec789472b70f38f? s=60&d=retro&r=g) ### 󠀁[So far so good!](https://wordpress.org/support/topic/so-far-so-good-1276/)󠁿 [Masoud Golchin](https://profiles.wordpress.org/masoudin/) ഓഗസ്റ്റ്‌ 8, 2025 Thanks for developing this plugin!It’s my #1 plugin for image optimization!
