Last month, the plan for WordPress to generate WebP images by default for new JPEG image uploads was put on hold for the upcoming 6.1 release after objections from lead developers. The original proposal had been merged into core at the end of July, despite significant critical feedback and concerns from WordPress’ developer community. Yesterday, the feature was reverted in response to Matt Mullenweg’s recent post about removing it from core in favor of development as a canonical plugin:I’ve been reading through all the conversation and issues here. I am interested in supporting new formats and improving performance, but I think this change being pushed by default to users when they upgrade to 6.1 is a lot for right now, including with some of the clunky interactions OSes still have around webp (and HEIC!) files.
WebP by Default Pulled from Upcoming WordPress 6.1 ReleaseI’m happy for support for working for webp and HEIC files to stay in core, as we should be liberal in what we accept and work with, but not with the change to convert everything to webp when JPEGs are uploaded.
Converter for Media – Optimize images | Convert WebP & AVIF
AVIF SUPPORTNow in the PRO version you can use AVIF as the output format for your images. The AVIF format is a new extension – is the successor to WebP. AVIF allows you to achieve even higher levels of image compression, and the quality of the converted images after image optimization is better than in WebP.
HOW DOES THIS WORK?
- If you have just installed the plugin, you can optimize images with one click. Image size will be smaller after generate webp!
- New images that will be added to the Media Library will be converted automatically.
- Our image optimizer does not modify your original images in any way. This means security for you and your files.
- When the browser loads an image, our plugin checks if it supports the WebP format. If so, the image in WebP format is loaded.
- The plugin does not make redirects in default mode, so the URL is always the same. Only the MIME type of the image changes to image/webp.
- No redirects means no cache issues, faster and trouble-free operation of your website.
- If you want to know more about how it works, check out the plugin FAQ below. It does not matter if the image display as an img HTML tag or you use background-image. It works always!
- In case rewriting by rules from .htaccess file is blocked, a mode is available which loads images via PHP file. Then image URLs are changed, but the logic of operation is the same as in the case of the default mode.
- The final result after image optimization is that your users download less than half of the data, and the website itself loads faster!
- You lose nothing – if you had to remove the plugin, it will remove everything after itself. It does not leave any trace, so you can check it with ease.
