jacmaes Posted October 8, 2022 Share Posted October 8, 2022 After a previous request for Webp support (6 years ago, times flies…) that Horst and Ryan kindly introduced in PW 3.0.132, I'm back with another request for a new image file format, AVIF, which has landed in almost all browsers. I'm actually surprised no one here in the PW community has been asking for AVIF support in ProcessWire as it seems to be provide much more consistent gains in compression and greater relative quality over Webp, and of course over good old JPEG. My experience using it definitely confirms this. I've been using Cloudinary to serve AVIF images to the browsers that support it, but of course I'd rather not use a third-party service, and use it natively in ProcessWire. Imagemagick supports AVIF if I'm not mistaken. Anyone else is interested? 20 Link to comment Share on other sites More sharing options...
jacmaes Posted May 13, 2023 Author Share Posted May 13, 2023 @horst as the image guru here, how feasible is it? I find that the lack of native AVIF support is an increasing performance issue for me. After more time using this new format, the compression gains are really quite amazing, and consistent (versus Webp). PW-powered sites — especially those that use lots of images such as photography / travel sites — could be much leaner and faster. Link to comment Share on other sites More sharing options...
BrendonKoz Posted May 19, 2023 Share Posted May 19, 2023 From a cursory search on the feasibility of this request: AVIF support does appear to be possible, but there would be more checks required to verify the server configuration meets the minimum requirements... ImageMagick supports AVIF as of v7.0.25 or later. PHP's GD library - as of PHP version 8.1 - supports AVIF when compiled with AVIF support, and also requires support via the libavif module. The libavif module must be version 0.8.2 or greater. At this point there might need to be a decision to determine how to handle image processing: Does a PNG get uploaded and processed and converted to both AVIF and WEBP, and then the smallest of the three options is what is served - or does the site admin decide one or the other (despite gains or losses)? Add in any variations and that's a lot of processing just for a single image. 1 Link to comment Share on other sites More sharing options...
ryangorley Posted October 6, 2023 Share Posted October 6, 2023 I'm a little late chiming in, but I'm building my first PW site and was looking to see if AVIF was supported and found this thread. I likewise am surprised this hasn't been requested more. AVIF is _much_ more impressive than WebP in my opinion. I would be happy if it behaved the same way as WebP support as described here: https://processwire.com/blog/posts/webp-images-in-pw/ I've yet to see an instance where AVIF was a larger image size than the source. Because browser support still isn't there on Edge, I'd want to use it with srcset fallbacks anyway. Link to comment Share on other sites More sharing options...
d'Hinnisdaël Posted October 20, 2023 Share Posted October 20, 2023 Native AVIF support would be great for creating performant sites. When WEBP support was added to the core, it was done as a one-off addition. AVIF could be added in the same way by accessing an $image->avif property on the image object. However — I think @BrendonKoz touched on this above — adding more alternative output formats will probably require some rethinking to keep this part of the core modular. We'll definitely see more image formats being developed in the future, and it'd be great to access them from a single property or as a single parameter with formats and fallbacks, e.g. $image->url(300, ['format' => 'webp,png']). 5 Link to comment Share on other sites More sharing options...
