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._ ## Installatie #### Installatie vanuit WordPress 1. Bezoek **Plugins > Nieuwe toevoegen**. 2. Search for **Modern Image Formats**. 3. Install and activate the **Modern Image Formats** plugin. #### Handmatige installatie 1. Upload de volledige `webp-uploads` map naar de `/wp-content/plugins/` folder. 2. Bezoek **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 ### Waar kan ik mijn feedback over de plugin indienen? Feedback wordt aangemoedigd en zeer op prijs gesteld, vooral omdat deze plugin mogelijk toekomstige WordPress core functies bevat. Als je suggesties of verzoeken hebt voor nieuwe functies, kun je deze [indienen als een probleem in het GitHub repository van het WordPress Performance Team](https://github.com/WordPress/performance/issues/new/choose). Als je hulp nodig hebt bij het oplossen van problemen of een vraag hebt over de plugin, maak dan [een nieuw onderwerp aan op ons ondersteuningsforum](https://wordpress.org/support/plugin/webp-uploads/#new-topic-0). ### Waar kan ik beveiligingsfouten rapporteren? Het prestatieteam en de WordPress community nemen beveiligingsfouten serieus. We waarderen je inspanningen om je bevindingen verantwoordelijk bekend te maken, en zullen ons best doen om je bijdragen te erkennen. Om een beveiligingsprobleem te melden, ga je naar de [WordPress HackerOne](https://hackerone.com/wordpress) programma. ### Hoe kan ik bijdragen aan de plugin? Bijdragen zijn altijd welkom! Lees meer over hoe je betrokken kunt raken in de [Handboek van het Core Performance Team](https://make.wordpress.org/performance/handbook/get-involved/). ### Ik heb de Modern Image Formats plugin geactiveerd, maar WebP afbeeldingen worden niet altijd gegenereerd wanneer ik een JPEG afbeelding upload. Waarom? Er zijn twee belangrijke redenen waarom een WebP afbeelding mogelijk niet wordt gegenereerd: 1. De Modern Image Formats plugin heeft vastgesteld dat de WebP versie van de geüploade JPEG afbeelding een grotere bestandsgrootte zou hebben dan de originele JPEG afbeelding, dus genereert het geen WebP versie. 2. De JPEG afbeelding is niet geüpload naar de [Mediabibliotheek](https://wordpress.com/support/media/). Op dit moment worden er alleen WebP versies gegenereerd voor afbeeldingen in de Mediabibliotheek. WebP versies worden niet gegenereerd voor JPEG afbeeldingen die op andere manieren aan je site worden toegevoegd, zoals in een template bestand of de [Customizer](https://wordpress.com/support/customizer/). ### Met de WebP Uploads plugin geactiveerd, zal de plugin JPEG en WebP versies genereren van elke afbeelding die ik upload? Standaard zal de Modern Image Formats plugin alleen WebP versies van de geüploade afbeeldingen genereren. Als je wil dat er zowel WebP **als** JPEG versies worden gegenereerd, kun je naar **Instellingen > media** gaan en de optie **Genereer JPEG bestanden naast WebP** inschakelen. ## Beoordelingen ![](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/) 22 maart 2026 Ich nutze dieses Plugin auf allen neuen Webseiten, damit Bilder automatisch nach AVIF konvertiert werden. Es funktionierte bisher immer ohne Probleme, deshalb kann ich es uneingeschränkt empfehlen. Ich hoffe es wird bald auch direkt in den WordPress Core übernommen. ![](https://secure.gravatar.com/avatar/92b7d005d1ba6b94b4e69814a40933f600fdcdcb097f2e1b5e4ae23d53535ee0? s=60&d=retro&r=g) ### 󠀁[Doesn’t work, support not helpful](https://wordpress.org/support/topic/doesnt-work-support-not-helpful/)󠁿 [primerpizza](https://profiles.wordpress.org/primerpizza/) 15 december 2025 2 reacties Been trying to get this thing to work but it just wont serve the generated images.

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/) 2 september 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/) 8 augustus 2025 Thanks for developing this plugin!It’s my #1 plugin for image optimization!
