Magento 2.4.4 does not support .webp upload

[H-Toine]

Preconditions and environment

• Magento 2.4.4

We currently have our own API set up to connect to Magento, and we provide content from this; including images. This includes various mime types, including webp.

Whenever we try to send that image through the Magento REST API, it says it does not support the mime type.

We have also tried uploading an image in the magento admin page for:

• Catalog -> Products -> Product -> Image Gallery -> Upload
  
• Content -> Page -> Insert Image -> Upload
  

Steps to reproduce

Below the steps to reproduce the issue with the REST API:

1. Set up Rest API
2. Send .webp image to the REST API as base64 through http://my.magento.com/rest/all/V1/products/{id}/media

{
    "entry": {
        "media_type": "image",
        "label": "My WEBP Image",
        "position": "3",
        "disabled": false,
        "types": [],
        "content": {
            "base64_encoded_data": "................",
            "type": "image/webp",
            "name": "WebP_Logo.webp"
        }
    }
}

Expected result

Image is added to the gallery of the specified product.

Actual result

Error 400 Bad Request: {"message":"The image MIME type is not valid or not supported."}.
On API Call: |POST| http://my.magento.com/rest/all/V1/products/{id}/media

Additional information

Magento\Framework\Api\ImageContentValidator

has the following allowed mime types:

private $defaultMimeTypes = [
    'image/jpg',
    'image/jpeg',
    'image/gif',
    'image/png',
];

There are other classes that have this same list of $defaultMimeTypes and $allowedMimeTypes.

Hi @Toinehaaijer ,

As per M2 document only JPG & PNG file format is supported.And webp file format is not supported.
Kindly refer the devdocs for your reference.

Let us know if you are facing any issue with other file formats.

Thanks

@engcom-Lima Thanks, I couldn't find that part of the docs. Is it possible to turn webp compatibility into a feature request?

[engcom-Lima]

@Toinehaaijer I will discuss internally for your query then, I will come back to you as soon as possible.

Hi @Toinehaaijer

We want to know your use case for using webp type format?
As I have seen some of the website not recommending that because some of the browser not suporting it, image thumbnail not was broken on there sites.

Thanks

[H-Toine]

Hi @engcom-Lima, our use case would be increasing performance/load times, as webp should be about 25%-34% smaller than a jpeg, and 26% smaller than a png. Also, it would increase flexibility for end users who don't really give file/mime types a second thought.

WEBP compatibility seems really good now, only IE (and KaiOS browser) don't support this: https://caniuse.com/webp

Hi @Toinehaaijer ,

Thanks for your contribution and collaboration.
On basis of your use case marking this ticket as feature request.

Thanks

@Toinehaaijer You should use Yireo plugin for webp support: https://www.yireo.com/software/magento-extensions/webp2
